Installing an EV charger at home

A home charger is one of the largest loads a house can take on. The supply and the route matter more than the charger itself.

A wall charger draws a substantial current for hours at a time, often overnight when other loads such as AC and water heaters are also running. Before choosing a charger, the property’s supply capacity and the distribution board are assessed: is there enough capacity, a spare way for a dedicated circuit, and the type of protection the charger manufacturer specifies?

Installation guides cover what a fitting or appliance needs from the electrics before it goes on the wall or ceiling.

Location and route follow. A charger in a villa car porch needs a protected cable route from the board, a weather-suitable position and convenient cable reach to the car. In apartment buildings, chargers in shared car parks involve the building management and its own electrical infrastructure, and approvals come first.

01In short

The points that matter most

  • Capacity first

    The supply and board must cope with long, heavy charging loads.

  • Dedicated circuit

    Chargers are supplied on their own circuit with suitable protection.

  • Buildings decide in apartments

    Shared car parks follow building rules and approvals.

02Detail

What is assessed

  • Supply and board

    Available capacity, spare ways and how charging fits with other large loads.

  • Protection

    The protective devices the charger manufacturer specifies for its circuit.

  • Cable route

    From the board to the parking position, protected from sun, vehicles and water.

  • Charger position

    Reach to the car’s charging port, shade where possible, and access for maintenance.

03Checklist

Before choosing a charger

  • Photograph the board

    And note whether the supply is single or three phase.

  • Measure the route

    From the board to the parking spot.

  • Ask the building

    If you live in an apartment or a managed community.

04Questions

Questions people ask

Can I charge from a normal socket?
Many cars allow slow charging from a socket, but long heavy use is better on a dedicated charger circuit.
Do I need three-phase power?
Not necessarily. Many chargers run on single phase; capacity is the key question.
Can charging be scheduled?
Most chargers and cars allow scheduling, which can help avoid peak household loads.
Will the charger work in summer heat?
Choose a unit rated for high temperatures and site it in shade where possible.
