Capalaba electrical job guide

Switchboard assessment

An older switchboard can raise questions about circuit protection, capacity and room for new equipment. Age alone does not prove that a complete replacement is required.

What to record

These details help frame the job without attempting electrical work yourself.

  1. 01Describe the proposed new load, such as solar, air conditioning or an EV charger.
  2. 02Note repeated trips, visible damage or missing labels without removing a cover.
  3. 03Ask which circuits are protected by safety switches and what assessment is needed.

The decision behind the job

A board assessment should explain the existing protection and the scope of any proposed change. A solar installation does not always mean a full board upgrade; the answer depends on the installation and the board.

Switchboard assessment questions

How can I tell whether my switchboard has a safety switch?
Look for a switch with a button marked T or Test. That is a useful clue, but a licensed electrician can confirm which circuits it protects.
How can I find out which circuits need extra safety-switch protection?
A licensed electrician can identify the existing devices and the circuits they cover, then explain options. Do not infer whole-home coverage from a single switch.
Will adding solar always require a full switchboard upgrade?
No. A solar system needs its own appropriate isolators and may need additional circuit protection, but the Electrical Safety Office says a whole-board upgrade is not required in every case. A site assessment determines the scope.
