Buzzing switchboard traced to a failing breaker
An audible buzzing from the switchboard in Balmain East was reported before it got worse. We found a breaker with a degraded internal contact, replaced it and thermal-imaged the board to rule out other hot spots. The tip of the Balmain peninsula where narrow heritage terraces and converted warehouse conversions often still carry original wiring that requires careful heritage-sensitive upgrades. Postcode 2041 is on our daily Inner West run, and every fault finding job there is quoted up front and completed to AS/NZS 3000.
