Ceramic Fuse Boards
A ceramic fuse board is an older type of switchboard that protects each circuit with a rewireable fuse: a length of fuse wire held in a ceramic carrier. When too much current flows, the wire melts and the circuit goes off. They were standard for decades but offer less protection than modern circuit breakers and safety switches, which is why they are commonly replaced.
Many older Sydney homes still have a ceramic fuse board. It may work, but it was designed for a very different level of household demand.
This page explains how these boards work, their limits and what an upgrade involves.
01 / Detail
Each circuit passes through a fuse carrier containing a piece of wire. If the current exceeds what the wire is rated for, the wire melts and breaks the circuit. Restoring power means replacing the wire.
02 / Detail
Fuse wire can be replaced with the wrong rating, which removes the protection it is meant to give. Rewireable fuses also do not detect earth leakage, which is what a safety switch does to reduce the risk of electric shock.
03 / Detail
Look for white ceramic carriers that pull out of the board, often with a small window or wire visible. Modern boards have switch-style circuit breakers instead.
04 / Detail
An upgrade replaces the fuses with circuit breakers and adds safety switch protection. The existing wiring is tested as each circuit is reconnected.
Frequently Asked Questions
Existing boards are not automatically illegal, but they do not meet current standards for new work, and many owners choose to upgrade.
We recommend calling an electrician, particularly if a fuse keeps blowing, as that points to a fault or overload.
Some insurers ask about the switchboard. Check with your insurer.
Not by itself, but testing during the upgrade identifies wiring issues.
