RCD (Residual Current Device)

Our experienced team can install domestic and commercial safety switches, RCDs and circuit breakers. These are imperative for safety for both you and the well being of your electrical appliances.


Did you know that installing at least 2 x Residual Current Devices (RCDs) at your house main switchboard will detect any fault in your wiring and electrical appliances? At Ballantyne Plumbing, Gas & Electrical, our experienced and competent Licensed Electricians can install your new RCD’s. We can also upgrade your old, ceramic still fuse switchboard with the most updated RCDs and circuit breakers, so you know that your safety is no longer compromised. Did you know that if you are selling your house or getting it ready to rent out, at least 2 x RCD’s must be installed in your main switchboard? Our competent Licensed Electrician will supply you with your copy of the Electrical Safety Certificate which needs to be produced before settlement can be achieved. Please ask our friendly staff the next time you give us a call, email us or ‘Request a Quote or Job’.

What is a RCD?

A Residual Current Device (RCD) monitors the flow of electricity through a circuit and detects problems which could potentially cause harm to residents. The RCD activates in 0.03 of a second preventing electric shock, injury and/or death.

A circuit breaker or fuse is not the same as a RCD.

  • Circuit breakers, fuses, and surge protectors protect electrical wiring and appliances.
  • RCDs protect people.

Testing the RCD

Homeowners, residents and tenants should regularly test the safety switch to ensure it is in working order and will provide protection in an electrical emergency. Our Licensed Electricians recommend testing every 3 months.

  • Step 1 – Press the TEST or ‘T’ button on the device – this should trip the RCD to the OFF position and cut off electricity to the circuit.
  • Step 2 – Reset by returning the switch to the ON position

RCD won’t reset? Leave the RCD switched off and unplug all the appliances, leads, and electrical equipment in your home. Try Step 2 again. If the RCD resets there could be an issue with one of your appliances. Gradually plug everything back into the power. If an appliance trips the switch when plugged back in, discontinue the use of the appliance and have it checked by a competent Licensed Electrician.

If the RCD fails to reset, even once all electrical equipment has been disconnected, contact a competent Licensed Electrician immediately for testing and repairs. Do not attempt electrical repairs yourself.

Why a minimum of 2 x RCDs?

Why do I need to have 2 RCDs fitted in my home electrical switchboard? When at least 2 RCDs are fitted, the Licensed Electrician will connect half of your house power point circuits and half of your house lighting circuit to the 1st RCD and the remaining half house power point circuits and lighting circuit to the 2nd RCD. The idea behind this design is if you have an electrical fault, the fault will trip one RCD only and you will lose power and lighting to only half of your house. This allows you to have some power for essential appliances (e.g. fridge, freezer, and the TV). To find the electrical fault, please contact Ballantyne Plumbing, Gas & Electrical, and our competent Licensed Electricians will attend your home, conduct a series of electrical tests and undertake a process of elimination to find and fix your electrical fault so your power can be switched back on as quickly as possible.
