Seven warning signs your wiring needs attention

Meter position and board upgrade with new tails and bonding

Warm sockets, burning smells and RCDs that trip at 3am are all telling you something. Here is how to read them.

Warmth, smells and scorch marks

A faceplate that is warm to the touch, a faint fishy or burning smell, or brown marks around a socket all point to a loose or overheating connection. Stop using the point and get it looked at.

Repeated tripping

An RCD that trips occasionally in a storm is one thing. One that trips every time the shower runs is telling you a circuit has deteriorated insulation or a faulty appliance is on it.

Old cable and old boards

Rubber or fabric insulated cable, rewireable fuse carriers and wooden backed boards belong to a different era. If your board has ceramic fuses, an upgrade is overdue.

Flickering and dimming

Lights that dim when a large appliance starts can indicate an undersized or loose supply connection, which is worth investigating before it fails properly.
