The Unit on the Wall Is the Cheap Half
Hanging a charge point takes an afternoon. Establishing that the supply behind it can carry another thirty-two amps for eight hours a night, in a house whose service was laid in when heating came out of a gas boiler, is the actual job — and most of that job is survey work, desk work and a conversation with the network operator that has to start weeks earlier.
The equipment side has largely converged. A wall unit with a tethered lead or a socket, a contactor, a control pilot circuit, residual current detection of some description, and increasingly a metering and communications stack the owner meets through a phone. Where manufacturers differ is in how they implement the protective functions, and that difference is the only part of the product specification that changes what you install around it.
The supply varies enormously. Two identical houses on one street can have different cutout fuses, different earthing arrangements, different tail sizes and completely different headroom, so the installation that is trivial at number 14 is a network application at number 16. Survey each property on its own terms and quote from what you found.
Design as though the vehicle does not exist. The charge point's configured rating governs the circuit; the vehicle's onboard charger only ever draws that or less; and a customer trading a car in has not altered the installation. Sizing to a particular vehicle is how a circuit turns out undersized for its replacement.
A Load That Does Not Behave Like the Others
A shower draws heavily for ten minutes. An oven cycles. A kettle finishes before a breaker has warmed up. A charge point pulls its full rated current, flat, for hours on end, and it does so on exactly the evenings when the heating, the cooking and the tumble dryer are also running. Nothing else in a dwelling has that duty at that magnitude.
Codes deal with it through a continuous-load rule: the circuit and its overcurrent device are sized above the actual current by a fixed margin, which is the same statement as saying a standard device may not be loaded past a fixed fraction of its rating for a sustained draw. Written either way round, the arithmetic hands you a device a size larger than the current alone would suggest.
The thermal consequence lands on the terminations and inside the enclosure, not on cable in free air. A board carrying a sustained forty amps through one way runs warmer than its schedule implies, the devices on either side of it lose headroom, and a tightly packed row of breakers in a small consumer unit is where that first becomes visible. Diversity is the other casualty: those factors exist in every load calculation because domestic loads are intermittent and uncorrelated with one another, and a charge point is neither of those things — which is why almost every code adds it to an assessment at full value with nothing taken off.
What Is Actually in the Cutout
Read the service before assessing anything. The fuse rating printed on the cutout carrier, the size and condition of the tails, the earthing arrangement, the meter position, and whether the assembly in front of you is the distributor's current standard or something fitted in 1978. Their records and what is physically installed disagree often enough that the check is worth the ten minutes.
A generous fuse rating is not permission to use it all. The real constraint sits upstream — the service cable into the property, the shared main running down the street, and the transformer at the end of it, every one of them sized on the assumption that no two houses peak together. Charge points break that assumption at street level, which is why so many jurisdictions require notification or approval for one, and why the answer occasionally comes back conditional.
Find the notification route early. Depending where you are, a charge point above a stated rating is either notified after energisation, applied for and approved beforehand, or permitted only where a demand-limiting function is fitted. Some networks take weeks to answer, and that is not a discovery to make on the morning of the install.
Look at what the service will physically tolerate as well. Undersized or heat-damaged tails, a meter box with nowhere left to bring a gland in, and a service head sitting where the new cable cannot reasonably get to it are all ordinary findings — and all of them belong in the quotation instead of in the day.
Photograph what you find while you are standing there. A cutout label, a tail size and an earthing arrangement captured on the survey are what let you answer the network's questions without going back, and they are also the evidence of what condition the service was in when you arrived at it.
The Diversity Argument
The decision that costs the customer real money is whether the existing service takes the new load. Two routes reach that answer. The prescriptive route assembles a demand from floor area, appliance ratings and the code's own demand factors, and produces a figure that is deliberately conservative for an occupied house. The evidence route uses a recording of the maximum demand this property actually reached, over a period the code specifies, with the charge point added on top at its full continuous rating.
For an existing dwelling the evidence route usually wins, because the prescriptive method assumes an appliance mix nobody has ever operated simultaneously. The conditions attached to it are the part worth reading closely: how long the recording must run, what season it has to cover, what happens if the property stood empty during part of it, and what must be added for loads already planned.
What that recording has to catch is a cold evening in an occupied house — the worst hour of the worst week. A logger left running through a mild fortnight in April returns a low maximum and supports a conclusion the installation will not survive.
Put the method beside the number in your records. When somebody comes to add a second charge point, a heat pump or a battery to this property, the next installer either builds on your assessment or repeats the whole exercise, and only one of those two is free.
Assemble the prescriptive demand for this dwelling and add the charge point at its full continuous rating: that combination is the worst-case figure any network application will be judged against.

This is a SIMPLIFIED illustrative version of the NEC 220 standard method, omitting several real-world factors (HVAC load, EV chargers, largest motor load addition, optional calculation method). Fixed appliances are carried at 100% because this page takes a VA total and not a count; 220.53 permits 75% where four or more fastened-in-place appliances are present, and a range or a dryer has its own table (220.55, 220.54) that this does not apply. It is NOT a substitute for a complete NEC Article 220 load calculation performed by a licensed electrician, which determines your actual required service size and is required for permitting. Always round up to the next standard breaker/service size (100A, 125A, 150A, 200A) and consult your electrician.

What this calculation does not cover
- Amps are not spaces. This sizes the SERVICE and says nothing about the panel's physical capacity — a dwelling can sit comfortably inside 100 A of calculated demand and still need a new panel because every breaker position is taken, the busbar is rated below what is being added to it, or the enclosure will not accept the breaker type the new circuits require. Panels get replaced for spaces at least as often as for amperage.
- The amperage is where the rest of the sizing starts, not where it ends. Service-entrance conductors, the grounding electrode conductor, the meter base, the mast or lateral and the utility's own drop or transformer all follow from this number and none of them fall out of it — and a dwelling service gets its own conductor allowance under NEC 310.12 rather than the general ampacity table, so the wire for a 200 A house is not the wire that table would give it.
- One dwelling unit. A second unit on the same service, an ADU, or a detached garage or workshop on a feeder are not added by piling their loads into these boxes: a multifamily service runs through 220.84's own demand table, and a feeder to an outbuilding is calculated as its own load under 220.40. Stacking two dwellings into this page understates both of them.
Demand Limiting Instead of a New Service
Where the assessment says the service is full, a dynamic load-management function is frequently cheaper than an upgrade by an order of magnitude. A current transformer clamped on the incoming tails reports total demand to the charge point, and the charge point throttles its own current — down to the minimum the charging standard allows, or to nothing at all — to hold the incomer below a configured set point.
Codes increasingly recognise the arrangement: an energy management system that limits demand may substitute for capacity, provided the limiting function forms part of listed equipment or an approved system, and provided the set point matches the supply's real limit. Where a network grants a connection conditionally, this is usually what the condition is.
The current transformer has to see everything. It goes on the supply side of every load it is meant to account for, including a second charge point, and its behaviour with a solar array or a battery in the property needs thinking through — a transformer fitted with reversed polarity or in the wrong position will report a comfortable demand at precisely the moment the demand is not comfortable.
Specify the failure mode. Ask what the charge point does when the signal from that transformer is lost: a unit reverting to full current on a communications failure has removed the only thing standing between this installation and a blown service fuse. On a constrained supply, fit the unit that falls back to a safe minimum and prove it does.
- Set the limit to the supply capacity you established, not to the fuse rating printed on the carrier.
- Confirm the current transformer's position and polarity against the manufacturer's instruction, with every load it must account for downstream of it.
- Start a charge at full current with the house quiet, and record the current at the incomer.
- Bring on the heaviest loads in the property one at a time — shower, oven, immersion — watching the charge point back off, and record the incomer current at each step.
- Interrupt the transformer signal deliberately and record what the charge point actually does.
- Leave the set point, the transformer location and the observed fallback behaviour on the certificate and with the owner.
Sizing the Circuit
The circuit comes off the charge point's rating, uplifted for continuous duty, and is then checked against everything the route takes away. The uplift comes first and gives you the overcurrent device; the conductor follows from that device rating, the termination temperature limit, the ambient the run passes through, and the company it keeps inside a duct or a bundle.
Configure the output before sizing anything, where the unit has an adjustable setting, and write the setting down. A charge point capable of forty amps and set to thirty-two is a thirty-two amp load only until somebody in the household changes it in an app. Where that setting is what makes the circuit adequate, it belongs on the certificate and behind whatever lock the equipment offers.
Give the circuit its own way in the board. Sharing defeats the object, complicates the residual current arrangement and quietly falsifies the load-management assumption. Where no way is free, a board change or a sub-board is part of the price, and finding that out at the survey is the difference between a quote and an argument.
Feed it the configured continuous rating and it returns the device size the continuous-load rule demands, which is the number both the conductor selection and the board capacity hang off.

What this calculation does not cover
- SIZES THE BREAKER, NOT THE SERVICE. The question that stops most EV installations is whether the existing service and panel can carry another continuous load of this size at all, and that is a whole-dwelling load calculation under the code's demand rules — not something a charger's own rating can answer. A panel with a spare double-pole space is not the same as a service with spare capacity.
- Where the service is short, load management is often the answer rather than an upgrade: a listed energy management system, or a charger that sheds when the range is on, lets the circuit be sized to what is actually available. Both are code-recognised and both are far cheaper than a new supply.
- The conductor is a separate calculation. Ampacity at the breaker size, derating for ambient temperature and for conductors sharing a raceway, the termination temperature rating, and voltage drop over what is often a long garage or driveway run all have to be satisfied — a correctly sized breaker on a conductor that fails any of those is the dangerous combination.
- Says nothing about the ground-fault protection, disconnecting means, or outdoor and wet-location requirements that apply to the equipment itself and vary with where it is mounted.
- A receptacle-connected charger and a hardwired one are treated differently by the code, and the choice affects both the protection required and whether the charger may be at the full 125% figure at all.
The Run Is Long, Outdoors, and Nobody Measured It
Charge points end up where the car parks, which is seldom near the board. A detached garage at the bottom of a garden, a driveway post twenty-five metres from the house, a bay two floors down in a shared car park — on runs like these voltage drop picks the conductor, not the ampacity table.
Sustained current across distance is the exact condition voltage drop punishes. A run sized on ampacity alone can deliver a voltage at the unit low enough to trip its own undervoltage protection, or low enough that it charges at a reduced rate the owner will notice within a week and report to you as a fault.
Measure the route along the cable and do not pace it out across the lawn. The cable follows the trench, climbs the wall, crosses a loft and comes back down; the straight line drawn on a plan is short by a third on most gardens. Add the vertical legs and the slack at both ends before you pick a size.
Then account for temperature. A conductor inside a duct against a south-facing wall, or buried alongside a heating main, will not carry what the table promises, and that correction compounds with the voltage-drop answer instead of replacing it.
Long run, full current, hours at a time: put the measured route length and the charging current in and read the drop straight off — on a garden run it usually calls for a bigger conductor than ampacity alone does.

What this calculation does not cover
- VOLTAGE DROP IS NOT AMPACITY, and the two are different questions with different answers. A conductor can stay inside the 3% suggestion and still be too small to carry the current without overheating, and it can be thermally adequate and still drop too much over a long run. Both checks have to be made, and only one of them is made here.
- The K constants are DC resistance at 75 °C (167 °F) for uncoated copper and for aluminum, the basis of NEC Chapter 9 Table 8. The table's size-by-size resistances differ from the single constant by a percent or so either way, and the table is not reproduced here. A conductor running cooler drops a little less and one at a 90 °C (194 °F) rating a little more; tinned (coated) copper has its own, slightly higher resistance.
- Treats the circuit as resistive, which is close for lighting, heating and most branch circuits. On a large AC feeder, and above all one in steel conduit feeding an inductive load, the conductor's reactance adds to the drop and the power factor matters; Table 9 of the same chapter carries the AC figures and is not reproduced here.
- Three phase assumes a balanced load and gives the drop between lines. A single-phase load taken from one line to neutral of a three-phase supply is a single-phase circuit: choose single phase and the line-to-neutral voltage.
- Aluminum conductors need terminations and devices listed for them; the code does not let dissimilar metals be joined except in a device listed for the purpose. Nothing here checks a termination, a lug or a splice.
- The 3% and 5% figures are suggestions in the code's informational notes rather than requirements, though a local amendment, an equipment maker's instructions or a specification can make a tighter figure binding.
Getting the Cable There
Outdoors the answer is normally buried, and buried means a duct with a draw rope in it, laid at the depth local rules set, warning tape above and fine fill around. Direct-buried armoured cable is permitted in plenty of places and it is also unrecoverable; a duct means the next cable into that garden does not need a second trench across a lawn somebody has since laid.
Size the duct for the pull and not for the cable. Bends consume tension exponentially, so each ninety-degree change multiplies what the cable behind it experiences, and three tight corners in a garden run can exceed a cable's sidewall pressure limit on a pull a straight route would have shrugged off. A draw pit at a corner costs less than a damaged cable and far less than a second trench.
Route it where a spade will not find it. Under the lawn that will get a pond, along the footprint of a future extension, or across the one strip obviously destined for decking — those are recoverable mistakes only where a record exists. Photograph and dimension the open trench from two fixed points on the building and hand the sketch to the owner.
The transitions do the damage. Glands correctly sized and rated for both the cable and the enclosure, no armour standing proud of a gland, and a drip loop on anything descending an external wall. An enclosure that filled with water because the cable ran downhill into it is a return visit with nothing to invoice.
Keep clear of what is already down there. Gas, water and telecoms all carry their own separation distances from a buried electrical duct, and a crossing over a drainage run wants recording as carefully as the depth does. Hand digging the last few inches wherever a service is expected is slower than swinging a mattock and considerably cheaper than repairing what the mattock finds.
Straight-run tension is the baseline that every bend then multiplies, so working it out for the length and cable weight in front of you tells you whether this route needs a draw pit or just a second pair of hands.

What this calculation does not cover
- Jamming and clearance are failure modes that are not forces, so no tension figure predicts them. Three cables of similar diameter can wedge side by side going through a bend when the conduit's inside diameter falls in a narrow band near three times the cable diameter, and the pull locks solid at a tension the winch will happily exceed and the cable will not survive. A single large conductor has the mirror problem — it needs a minimum clearance to the conduit wall through every bend. Check the geometry of what is going in before trusting any number here.
- Cold changes the pull and can end it. Jacket and insulation stiffen as the temperature drops, so the same cable in the same conduit pulls appreciably harder in winter than the friction coefficient above suggests, and most cables carry a minimum installation temperature below which the jacket cracks rather than bends. Neither the friction figure nor the weight in this calculation moves with temperature; warming the reel before the pull does more than either of them.
- This is what the conduit costs you. The reel adds its own before the cable reaches the conduit at all — a heavy drum with a stiff brake, a feed that is not squared up with the conduit mouth, or a sheave set at the wrong angle each contribute back-tension and an extra effective bend right at the head of the run, and being at the head, everything downstream multiplies it.
The Protective Device Has to See DC
A vehicle's onboard charger is a power-electronic converter, and under certain fault conditions it can push a smooth direct residual current onto the supply. Smooth DC does not alternate, so it generates no signal in the core of a conventional residual current device — and worse, it can saturate that core and blind the device to the alternating fault current it was fitted to catch.
The answer is either a device rated to detect smooth DC residual current, or a lesser type paired with a detection function that disconnects the supply once smooth DC above a low threshold appears. Many charge points now integrate that detection, which is why the manufacturer's declaration counts for more here than the marking on the breaker: what has to be established is that the installed device and the equipment, taken together, cover every fault type the standard lists.
Do not share the device. A charge point sitting behind a residual current device that also protects sockets and lighting adds its own standing leakage to that bank, and an earth fault on the charge point takes the rest of the bank down with it. Dedicated protection on a dedicated circuit is the arrangement every code has been moving toward for years — and whichever device ends up on it, that integral test button proves the mechanism and nothing more. Trip current and trip time are measured with an instrument at the outlet and recorded, and on equipment carrying its own detection function the manufacturer's test sequence is a separate check with separate pass criteria.
| Device type | Responds to | What that leaves on a charge point circuit |
|---|---|---|
| Type AC | Alternating residual current only | Unsuitable — pulsating and smooth DC components both pass it unseen |
| Type A | Alternating plus pulsating DC residual current | Usable only where a separate function detects smooth DC and disconnects |
| Type F | Type A duties plus composite and higher-frequency residual current | Suits frequency-controlled loads; the smooth DC question is still open |
| Type B | All of the above, including smooth DC residual current | Covers the fault types unaided, at a cost in price and module width |
| Type A with DC detection inside the equipment | Type A duties, with the equipment disconnecting on smooth DC | The common arrangement; the equipment declaration is what proves it |
The Earth Outside the House
A charge point outdoors, with somebody standing on wet ground holding a connector bonded to a vehicle body, is a different exposure from an appliance indoors. Where the distributor provides the earth through a conductor combined with the supply neutral, a break in that conductor upstream can lift the installation's earthed metalwork to a dangerous potential relative to the ground underfoot — and the vehicle is the metalwork in the person's hands.
Three arrangements answer it. Provide a separate earth electrode for the charge point and keep it clear of the building's earthed metalwork by the separation the rules require. Fit equipment with an integral function that watches the supply voltage and disconnects all live conductors, earth reference included, when it deviates. Or establish that the supply arrangement at this property is not the type that carries the risk in the first place.
The separation route is the one that fails silently. An electrode driven three metres from a house that has a buried metal water pipe, a steel fence and a copper gas main radiating out of it is not a separated earth, and nothing in the installation's behaviour will ever reveal that. Where the plot cannot deliver genuine separation, the equipment-based route is the honest choice and not the lazy one.
Whichever route is taken gets recorded on the certificate and explained to the owner, because the next person working on this installation has to know why there is an electrode in the lawn, or why the charge point drops out during a supply voltage excursion that nothing else in the house notices.
Handing It Over
Commission the installation and the equipment as two separate exercises. The installation takes the ordinary dead and live sequence — continuity, insulation resistance, polarity, loop impedance, residual current device operation. The equipment takes the manufacturer's own procedure, which usually means an adapter that simulates a vehicle through the control pilot states so the contactor, the protective functions and the connector lock all operate under a real test.
Then prove the parts specific to this job: the demand-limiting set point and its fallback, the configured output current, the earthing decision you made and why, and the position of everything buried. Photograph the open trench, the current transformer, the board and the unit's settings screen, and attach all of it to the record.
The owner conversation is short and it heads off most callbacks. What the charge point does when the house is busy, why it sometimes charges more slowly than last week, what changing a setting in the app does to the compliance of the circuit, and why nothing about this installation should ever meet an adaptor or a domestic extension lead. Say it out loud, then leave it written down.
Finish on running cost, because that is the next question anyway. Their tariff, their battery and their pattern of driving produce a figure per charge and a figure per mile, and putting real numbers in front of them on the day converts a vague expectation into something they can check against a bill.
The owner's first question after energisation is what a full charge costs them, and answering it there and then with their own tariff and battery size is worth more than any leaflet left on the worktop.

What this calculation does not cover
- It prices the energy stored in the battery, not the energy the meter records. Onboard-charger and cable losses, battery thermal conditioning and cabin preconditioning all draw billed kWh this calculation ignores, so the real bill runs above the figure shown — more so in cold weather and on slow Level 1 charging.
- One flat rate per kWh is all it takes. Time-of-use bands, tiered block rates, standing or daily supply charges, demand charges, taxes and levies not already inside the rate you type, and any solar self-consumption or export credit are all outside the model.
- Range is whatever you type, held fixed. Cold weather, cabin heating, speed, terrain, load, tyres and pack degradation over the vehicle's life all move miles per charge, and there is no seasonal or degradation term here — the cost per mile is only as good as the range figure you enter.
- It assumes a single charge from empty to full. It does not model partial top-ups, a routine charge limit set below 100%, or a mix that includes public or DC fast charging with its own per-kWh premium, session fees and subscription plans.
- This is a cost estimate, not an electrical design. It says nothing about whether the circuit, cable, protective device or supply capacity can serve a charge point, and nothing about the added load on the existing service — sizing and protecting an EV charge point circuit is a separate calculation under the wiring rules in force, and the installation itself is regulated work in most jurisdictions.
