Switchboard and safety-switch questions

A safety switch is designed to cut power when it detects a leakage current that could cause electric shock. Ask a licensed electrician which of your circuits are protected.

No. A circuit breaker protects wiring from overloads and short circuits. A safety switch helps protect people from electric shock. Your board may contain both.

Look for a device marked RCD or safety switch with a T or test button on the closed board. If you cannot tell which circuits it covers, ask a licensed electrician to check.

One safety switch may not protect every circuit. Have a licensed electrician check your board and explain the coverage and any changes required for proposed work.

No. They reduce the risk of electric shock but cannot prevent every injury or replace safe use and maintenance. Follow the manufacturer's testing instructions and seek advice if a test fails.

You can use the marked test button without opening the board. This cuts power to the circuits it protects. If the switch does not trip or reset as expected, contact a licensed electrician.

A fault may still be present. Avoid repeatedly resetting it or opening the board; contact a licensed electrician to investigate.

The Queensland Electrical Safety Office recommends pressing the test button every three months. Follow the device manufacturer's instructions too, and if the switch does not trip or you are unsure which device to test, ask a licensed electrician.

There is no useful age guarantee for an individual device. If it is damaged, fails a test or trips unexpectedly, have a licensed electrician assess it.

Ask a licensed electrician to identify which circuits have safety-switch protection and whether planned work or current requirements call for changes.

The price depends on the existing board, circuits, protection, access and any supply coordination. Ask for a written quote after inspection, including exclusions.

Timing depends on the inspected work and whether another party must coordinate the supply or meter. Ask the electrician for a schedule with the quote.

A licensed electrician needs to assess the existing board and circuits before advising on scope.

Perhaps, but the appliance alone does not decide it. Give the electrician the model and proposed position so they can assess the circuits and supply.

It may involve moving or changing meter or supply equipment, with network coordination. Ask the electrician what work, fees and third-party steps are included in the written quote.

Consider an inspection if the board is damaged, lacks suitable protection, trips repeatedly or may need to support new equipment. The electrician should explain any recommendation based on what is installed.

Repeated tripping can have several causes, including a faulty appliance or circuit. Note what lost power and when, avoid repeated resets, and ask a licensed electrician to investigate.

Stop using the outlet and do not touch or diagnose it. Treat it as an electrical-safety concern; call emergency services if there is smoke, fire or immediate danger, then seek licensed-electrician advice.

For homes, yes in two common situations. When a home is sold, the seller must tell the buyer in writing, by the date of possession, whether a safety switch protects the power-point circuits; if not, the buyer must have one installed within 90 days after taking possession. For a residential tenancy, if a power-point circuit lacks an approved safety switch, the owner must have one installed within 90 days after the tenancy starts. These deadlines do not mean an electrical danger can wait: for smoke, fire or immediate danger, use emergency services. Other electrical work can bring further requirements, so ask a licensed electrician to check your board.

Some connection, metering and supply changes require network coordination. Describe the proposed work to a licensed electrician, who can confirm the steps that apply.
