7 signs your Adelaide home may need a switchboard upgrade

Quick answerCeramic fuses, limited safety-switch protection, heat damage, repeated tripping, no spare capacity, older wiring and planned high-load equipment are all reasons to request a switchboard assessment.

1. Ceramic rewireable fuses

Older fuse boards can indicate that protection and enclosure arrangements predate modern expectations. Their presence does not diagnose the whole installation, but it is a good reason to have the board assessed.

2. Incomplete safety-switch protection

Safety switches reduce electric-shock risk by disconnecting supply when leakage is detected. An electrician can test what circuits are protected and advise whether the board meets current requirements for the proposed work.

3. Heat, buzzing or discolouration

A hot electrical smell, buzzing, scorch marks or melted plastic needs prompt professional attention. Do not remove covers or touch affected equipment. If there is smoke, fire or immediate danger, call 000.

4–7. Tripping, crowding, renovations and new loads

Repeated unexplained trips, an overcrowded board, renovation work or a planned EV charger or large air conditioner can all expose capacity and protection limitations. The right next step is a site assessment, not guessing from a photo alone.

What should you do next?

For a site-specific answer, describe the property, symptoms and timing. A licensed professional can then confirm what testing or inspection is required before quoting.
