Safety Switch

Safety switches, also known as RCDs (Residual Current Devices) are safety devices that detect disruption in the electrical flow caused by a circuit overload or leak, then quickly cut the power supply to prevent shock or electric fire.

We offer inspection, installation and replacement for safety switches to homes and businesses across Sydney. Every property is different and some may need more than one safety switch to be deemed safe. If you’re unsure about how many are required for your property, give us a call and let our certified electricians determine it for you.

How Safety Switches Can Protect Your Home

Responsible for preventing up to 40% of house fires caused by electrical faults every year, RCDs are required by law to be installed in certain locations, such as in new homes and on construction sites.

Safety switches protect you when an electrical fault is detected. They monitor the flow of electricity through a circuit. If there is a leakage of current, they turn off the electricity in a fraction of a second and protect you from serious electric shock.


Always meeting industry standards

It is important to make sure that your property and equipment are safe and compliant with current Australian Safety Standards. For that reason, we are heavily invested in your safety.

With extensive accreditation of our services, our fully licensed and insured safety switch electricians are trained to ensure complete safety and compliance. We always ensure your home adheres to Australian Law which mandates each circuit in a household should have its own safety switch, keeping you and your family safe.

Personal and Property Protection
A safety switch is designed to detect electrical faults and quickly shut off power supply, preventing electric shock or electrocution. By promptly cutting off the power, it minimises the risk of severe injuries or even loss of life. Additionally, it safeguards your property from electrical fires that can cause extensive damage.
Early Fault Detection
Safety switches constantly monitor the flow of electricity, identifying any abnormalities or faults in the electrical circuit. They can detect even small leakage currents that may indicate potential hazards. By detecting faults early, a safety switch helps prevent electrical accidents before they escalate into more significant safety concerns.
Fast Response Time
Safety switches react swiftly to electrical faults, typically within milliseconds. Their rapid response significantly reduces the risk of injuries and damages. Whether it's a faulty appliance, damaged wiring, or a ground fault, the safety switch acts as a reliable safety measure that provides peace of mind.
Compliance with Electrical Standards
Safety switches are mandatory in many residential and commercial settings, aligning with electrical safety standards and regulations. Installing a safety switch ensures your property meets the required safety codes, making it not only a smart choice but also a legal obligation.
Flexibility and Customisation
Safety switches are available in various types and configurations, allowing flexibility to suit your specific needs. They can be installed to protect individual circuits or cover the entire electrical system. Moreover, safety switches can be combined with other safety measures to enhance electrical protection in your home.

Frequently asked questions

Is one safety switch enough?
We recommend all circuits to have safety switch protection. Older properties often only have one safety switch covering the entire house, which can be inconvenient and dangerous because if it trips and shuts off all the power in your property.

This is why each circuit in your property needs a safety switch. That way, if one appliance malfunctions, only that particular circuit will be affected.
What are the different types of safety switches?
There are three common types of safety switches. For circuit protection, switchboard switches are installed on the main switchboard, powerpoint switches are built into a single power point, protecting a single circuit and portable switches are installed on extension cords.

Have to say it's rare to come across any companies such as selectrical services these days. Their custom service is excellent and backed with prompt service. They would text you to inform when their electrician would arrive. When they promise something, they would keep their promise. We had really good experience having them to carry out electrical work.

Emergency call out today, our switchboard started to smoke and our power had to be turned off. With temperatures over 35 and elderly parents it was extremely stressful. I can not speak highly enough of this company. Not only did they turn up within a few hours but the job was done promptly and efficiently. Thank you so much for your professional service !! I will highly recommend you!
