The railway of the 1880s got things moving, and the years after the First World War pushed it on, leaving a solid run of Federation and interwar Californian bungalows across broad, shaded blocks. Post-war brick arrived later, with townhouse pockets settling near the station.

You read that timeline straight off the wiring. Brick, double-brick and weatherboard houses each followed the rules current when they went up, which is not where the rules sit now.

Original fuse-wire boards. Many of these long-held homes still run the panel they were built with. It handles the basics but falls a generation short of proper breakers, so the upgrade tends to arrive alongside new cooling or a kitchen extension.

Circuits with no RCD. Homes from before safety switches were required commonly missed them across power and lighting alike. Retrofitting them makes most sense mid-renovation, before any extra load goes on.

Wander Yarrara Road, or the quieter turns off Trebor Road, and it repeats: houses held in one family across the decades, added to more than once, with the board left behind each time.

A globe that flutters or a switch always nagging is the circuit flagging trouble. We trace a fault like lights that flicker, or a run of sockets carrying too much, straight back to its root and settle it there.
