EV charger installation itself — running the circuit and mounting the unit — is typically Level 1 electrician work. But a growing share of installs stall at quoting stage once it's clear the existing supply can't support the charger without upgrading first.
When You Only Need Level 1
If your switchboard already has sufficient supply capacity and available circuit space, installing a home EV charger is a standard Level 1 job: a dedicated circuit is run from the switchboard to the charger location, with appropriate circuit protection.
When You Need Level 2 First
If your switchboard is at or near capacity, especially in older homes on a standard single-phase supply already running ducted air conditioning or electric hot water, a fast EV charger can push demand past what your connection can safely deliver. This is where a switchboard upgrade or three-phase conversion — genuine Level 2 ASP work — becomes necessary before the charger can go in.
Multiple EV chargers at a strata property or commercial site almost always require a Level 2 assessment of supply capacity and often a dedicated network connection upgrade.
Getting It Right the First Time
Because Sydney Power Group is licensed for both scopes, we can assess your existing supply, complete any required upgrade, and coordinate the final circuit installation without handing the job to a second trade partway through.
