EV charger + switchboard upgrade in Sunbury — why we check the board first

Today's Sunbury job started as "just an EV charger" and became a perfect example of why we assess the switchboard before quoting.

What we found

The home still had a ceramic fuse board from the 90s — no RCDs, no spare ways, and no safe path for a 32 A continuous load. Installing a charger on that board would have been non-compliant and genuinely dangerous.

What we did

  • Full switchboard upgrade: RCBOs on all circuits, surge protection, labelled and certified
  • 7 kW single-phase charger on its own protected circuit
  • Load management configured so the charger backs off when the oven and aircon are running

The result

The owner charges overnight on off-peak rates for roughly a quarter of public-charging cost — and the house is safer than it's been in thirty years. Certificate of Electrical Safety issued on completion.
