What wiring does a home EV charger need?

Quick answer

A home EV charger draws a high, sustained current, so it needs its own dedicated circuit sized to the charger — not a shared socket. A typical home AC ('Level 2'-style) charger runs on a dedicated higher-current circuit with its own correctly-rated MCB and an RCCB for shock protection.

Because charging runs for hours at high load, the cable must be correctly sized for the current and run length (see ampacity), with proper earthing. An outdoor or garage charge point also needs weather-suitable wiring. For the charging cable itself, see what cables an EV charging setup needs.

Always have an EV circuit designed and installed by a qualified electrician using quality house wires and cables. Contact APAR to discuss suitable cable.
