Ceramic rewireable fuses are still found in many older Sydney switchboards, and they are one of the clearest signs a board is overdue for an upgrade. They offer no protection against electric shock and can be incorrectly rewired with the wrong fuse wire, leaving circuits unprotected. Sydney Power Group (SPG) replaces them with modern circuit breakers and RCBOs.
SPG is a Level 2 ASP electrician authorised across Ausgrid, Endeavour Energy and Essential Energy, so alongside swapping out the fuses we can address any main switch, consumer mains or metering work that requires Level 2 accreditation.
Why Ceramic Fuses Should Go
Rewireable ceramic fuses rely on a strand of fuse wire that melts under overload. They are slow, easy to misuse and provide zero earth-leakage protection, so they cannot save you from a shock. When they blow you are left in the dark fiddling with fuse wire instead of simply flicking a breaker back on.
Replacing them with circuit breakers and RCBOs gives you instant reset, reliable overload protection and, with RCBOs, shock protection on each individual circuit.

Circuit Breakers Or RCBOs
For many boards we fit circuit breakers plus a shared safety switch, but the best outcome is per-circuit RCBO installation, which combines overload and earth-leakage protection so a fault on one circuit never takes out the rest of the house. We assess your board and recommend the right mix.
Old boards holding ceramic fuses are often mounted on asbestos backing boards, so we identify and handle these materials safely and appropriately during the changeover.
