Switchboard Upgrades in Kirrawee, Done Right

How a Switchboard Upgrade Works in Kirrawee

Kirrawee has a significant stock of brick-veneer and fibro homes built between the 1950s and 1980s. Many still carry original ceramic fuse boards — some with hand-wound fuse wire — that were never designed to handle modern appliances like reverse-cycle air conditioners, induction cooktops, or EV chargers. When those loads land on an undersized board, the result is nuisance tripping at best and overheating at worst.

The upgrade process starts with a full load assessment: we check the incoming supply capacity, map every existing circuit, and identify any double-tapping, undersized cabling, or corroded neutral links before the board is touched. In older Kirrawee properties it is common to find aluminium sub-mains run from the street pit — we inspect the condition of those connections at the same time, because a new board on a deteriorating sub-main is a half-measure.

Once the scope is confirmed we isolate the supply, remove the old enclosure, and install a new DIN-rail board with correctly rated miniature circuit breakers and — critically — safety switches (RCDs) on every circuit as required under current NSW regulations. Each circuit is labelled clearly, torque-checked, and tested with a calibrated RCD tester before power is restored. We then complete and lodge the required Certificate of Compliance with Ausgrid or Endeavour Energy so your records are clean.

The whole process typically takes a single day for a standard residential board. If your Kirrawee home has a granny flat, a workshop sub-board, or solar already installed, we scope that additional work upfront so there are no surprises on the day.
