Home EV charger electrical plan: prepare a clear installation in France

Why prepare the plan before choosing the charger?

The power printed on a charger is only one part of the design. The vehicle, parking time, electricity contract, existing distribution board and distance to the parking space all affect the final solution.

An electrical plan brings these decisions together. It shows the actual parking position, the side of the vehicle charging port, the possible cable route and the equipment needed near the distribution board.

• Location of the wallbox or reinforced outlet.
• Distance and route between the distribution board and parking space.
• Indoor, façade, garage or underground conduit route.
• Possible location of load management and sub-metering equipment.

Reinforced outlet or wallbox: what should the plan show?

A reinforced outlet can fit a low daily mileage when the vehicle remains parked for a long time. A wallbox usually offers more power, finer load control and scheduling or monitoring features.

Common comparison points include up to 3.7 kW for slower charging, 7.4 kW on single phase, and 11 or 22 kW when both the vehicle and a three-phase installation support it. The actual rating must be validated against the property and the vehicle.

• Daily driving range to recover.
• Usual parking duration at home.
• Maximum AC power accepted by the vehicle.
• Available property supply and load-management options.

3.7, 7.4, 11 or 22 kW: which power should you install?

Charger power is measured in kilowatts (kW), while kilowatt-hours (kWh) measure battery capacity. The power actually received by the car is always limited by the weakest link: charger, vehicle onboard charger, electricity contract, or property installation.

The most powerful wallbox is therefore not automatically the best choice. When a car remains parked overnight, 3.7 or 7.4 kW may be sufficient; 11 or 22 kW is mainly relevant with a three-phase supply, a compatible vehicle, and a need for faster charging.

• 3.7 kW — single phase, approximately 16 A: slower charging for a reinforced outlet or modest daily needs. An authorised professional is still required; only IRVE qualification may be exempt under the legal conditions.
• 7.4 kW — single phase, approximately 32 A: a common domestic wallbox power for recovering more range overnight. An IRVE-qualified installer is mandatory.
• 11 kW — three phase, approximately 16 A per phase: faster charging when both the property and the vehicle onboard charger support three phase. An IRVE-qualified installer is mandatory.
• 22 kW — three phase, approximately 32 A per phase: high power requiring a compatible installation, electricity contract, and vehicle. Many vehicles limit AC charging to 11 kW. An IRVE-qualified installer is mandatory.

What should appear on the electrical plan?

The plan should be detailed enough to prepare a quotation without pretending to replace the installer’s technical study. Show the charge point, its dedicated route to the distribution board and the visible constraints along that route.

In Planelico, you can distinguish a wall-mounted charger, pedestal charger, reinforced outlet or future provision. Dedicated symbols also cover dynamic load management, sub-metering, emergency isolation and an outdoor conduit.

After placing a wallbox, select it in the editor to choose 3.7, 7.4, 11, or 22 kW and state whether 6 mA DC detection is integrated. “Generate circuits & panel” then creates the dedicated circuit and corresponding pre-sizing.

• Charger, reinforced outlet or provision for future work.
• Dedicated circuit kept separate from general outlets.
• Dynamic load manager linked to the meter or distribution board.
• Conduit, penetrations and approximate route length.
• Notes about access, outdoor exposure and future extensions.

NF C 15-100 and IRVE qualification in France

NF C 15-100-7-722 specifically covers supplies for electric vehicles. AFNOR highlights that a dedicated outlet or charger must be served by a dedicated circuit. Protection, conductor size and installation method then depend on the real project.

Every charging point installation in France requires an authorised professional under article D.353-2 of the French Energy Code. This also applies at 3.7 kW or below: the threshold does not make DIY installation generally permitted.

Up to 3.7 kW, specific IRVE qualification may not be required when the infrastructure is installed in a private residential building or dependency and is not open to the public. Above 3.7 kW, the authorised professional must hold IRVE qualification.

• Every charging point: installation by an authorised professional.
• 3.7 kW or below in the private case defined by law: only IRVE qualification may be exempt.
• Above 3.7 kW: IRVE qualification is mandatory.
• In every case: dedicated circuit and final sizing validated against the property and charger instructions.

Plan smart charging before increasing the supply

Dynamic load management adapts charging to the home’s live demand. It can temporarily reduce the charger when heating, cooking or hot-water loads are high and increase it again when capacity becomes available.

Enedis reports that 35% of private users systematically control their charging. The off-peak reform launched in November 2025 also moves some periods into the early afternoon, so the plan can anticipate a control or smart-meter link rather than showing only a power cable.

Financial support in 2026: avoid outdated claims

The French national tax credit for a smart charger applied to eligible expenses paid by 31 December 2025. Service-Public states that it was removed for expenses paid from 1 January 2026.

Other support can depend on the property, condominium, location or current programme. Always check the conditions when signing the quotation instead of relying on an older article.

What the plan does not replace

The plan prepares the location, route and desired equipment. On its own it does not calculate voltage drop, final conductor size, protective devices, earthing, diversity or the suitability of the existing distribution board.

Give the PDF to a qualified installer so they can inspect the property, size the circuit and confirm the usable charging power before work starts.
