EV Charger Installation Wayville: A Wall Charger for an Older Inner-South Home

Age alone does not rule a house out. What matters is the type of switchboard and how much spare capacity the home has once the oven, hot water and air conditioning are running.

In an older house rewired in stages, some circuits may still run on original cabling. The electrician checks those cables before connecting a charger to them.

The electrician adds up what your home already uses, then decides whether the charger fits on the existing board or needs a change first.

Brittle insulation or crowded circuits are better found before the charger goes in than after the car has been plugged in for a week.

Boards with ceramic fuses or no spare space for a new circuit need work first. If the board has room and the supply has spare capacity once your other appliances are counted, the charger can often go in without board work.

Cost is the worry for most owners once the switchboard gets involved. Ask for the switchboard work to be itemised on the written quote, so you can see what the board costs separately from the charger.

The goal is a charger that does not trip other circuits when the car charges overnight.

The board is often at the opposite end of the house from the driveway or carport. That is a cable problem, not a dead end. A longer run means more cable and more labour, so it moves the price, and the written quote shows it.

The electrician runs the cable through the roof space, under the floor or along an outside wall in neat conduit, whichever suits how the house is built. Under-floor runs suit raised timber floors. Slab-on-ground homes usually go through the roof space or along an outside wall in conduit.

Units and townhouses bring a different question. Where the car park is shared, the body corporate has a say, and the electrician works out which meter and which supply the charger connects to.

A standard powerpoint with the portable lead that comes with the car works, but slowly. That lead is called a granny charger. It may struggle to replace what you use on busy driving days, especially if the car is only home for a few hours.

For most homes, a fixed wall charger on its own circuit is the usual answer. Level 2 charging like this runs faster and holds up to nightly use.

A charger you have already bought is worth mentioning. The electrician checks that the model suits your car and your supply before fitting it.

A charger works alongside rooftop solar or a battery. The electrician sets it up so the car draws sensibly from the system instead of fighting it.

In South Australia, in-scope AC wall chargers installed from 1 July 2024 are set up to the Office of the Technical Regulator guideline, including demand response where it applies. Demand response lets the network ease the charger's load when supply is tight.

Every job ends with an electronic Certificate of Compliance, as South Australian law requires.

Wayville is a compact inner suburb about 3 kilometres south of the Adelaide CBD, in the City of Unley council area. It has 1,121 properties, with older houses sitting alongside newer units.

If your car parks on the street near the Adelaide Showgrounds, Wayville Reserve or the South Parklands, a kerbside space has no wall to mount a charger on. The charger then needs an off-street spot at the house.

Families make up 64% of Wayville households, with an average of 2.3 people per house, so two cars on one driveway is a real possibility. If both are EVs, tell the electrician how far each travels and when each is home. One charger may cover both.
