An RCD (Residual Current Device), commonly called a Safety Switch, is an electrical safety device designed to protect people from electric shock. It continuously monitors the flow of electricity and automatically disconnects the power if it detects electricity leaking from a circuit, such as through a damaged appliance or a person. While an RCD cannot prevent all electric shocks, it significantly reduces the risk of serious injury or death.

An RCD is different from a circuit breaker. An RCD protects people by detecting electrical leakage, while a circuit breaker protects property by switching off power if a circuit becomes overloaded or develops a short circuit, helping to prevent overheating and electrical fires.

Most RCDs have a clearly marked TEST button on the front. This button allows users to carry out a simple manual test to confirm the RCD's trip mechanism is operating correctly and should be tested regularly as part of routine facility maintenance.

 

RCDs are mechanical devices and, like any safety equipment, can fail.

Regular testing confirms they:

Because Scout facilities are used by young people and the public, ensuring RCDs are working correctly is an important part of managing electrical safety.

Scout Queensland, and many local government areas require periodic professional RCD testing. There are two different types of testing.

Every RCD has a small TEST button.

Pressing this button checks that the internal trip mechanism still operates.

This is a simple check that can be completed by a Scout volunteer.

How often?

Scouts Queensland recommends:

• Every 6 months 

• After major electrical work 

• If there is any concern the RCD may not be operating correctly 

How to test

1. Warn anyone using electrical equipment. 

2. Press the TEST button. 

3. The switch should immediately trip to OFF. 

4. Reset the switch. 

5. Confirm power has returned. 

Record the result.

In addition to the routine push-button test, each RCD should be professionally tested by a licensed electrician at least every 12 months, or more frequently if required by your council, lease agreement or when major maintenance is performed.

Using specialised test equipment, the electrician checks the RCD's trip time, trip current and overall operation to ensure it complies with Australian Standards. Professional testing is also recommended after an RCD has been replaced, following significant electrical work, or if the manual TEST button check fails.

Records and Testing Labels

Professional testing is typically identified by a tag or label attached to the switchboard showing the test date, next due date and electrician's details. Some councils undertake this testing on behalf of Scout Groups and will apply their own tag, however this should not be assumed. Volunteer push-button tests do not require a tag but should always be recorded in the maintenance register.

If the RCD:

• Does not trip, 

• Will not reset, 

• Trips repeatedly without reason, or 

• Appears damaged, 

Arrange for a licensed electrician to inspect the installation as soon as possible.

If the failure affects the safety of the building, consider suspending activities until repairs have been completed.

Record the fault and the corrective action taken.

✔ Test every RCD using the TEST button every six months.

✔ Record every user test.

✔ Arrange professional testing at least every twelve months, if not arranged by council

✔ Keep all electrician reports.

✔ Check for current testing labels.

✔ Report any faults immediately.

✔ Never ignore an RCD that will not operate correctly.

It confirms the mechanism operates but does not verify the RCD trips within the required time. Professional testing should still be undertaken where required.

Yes. No electrical licence is required because the switchboard remains closed and only the TEST button is pressed.

No. Older buildings may not have RCD protection on every circuit. If you are unsure, ask a licensed electrician.

Do not repeatedly reset the RCD. There may be an electrical fault. Disconnect appliances where possible and arrange for a licensed electrician to investigate.
