RCD Installation Perth
We light up every room we enter!
An RCD, or Residual Current Device, is a device that switches off electricity immediately if there are any faults detected. This can potentially save a person’s life.
How does an RCD work?
RCDs monitor the electric current constantly and if there is any fluctuation caused by something, like someone touching a wire, the device turns off the current within milliseconds. Upgrading your switchboard to an RCD will save you and your family from electrocution 97% of the time, and they are simple for an electrician Perth to install. They can also protect your house from electrical fires caused by rogue wiring, and are used all over the world. An RCD is the most common safety switch used in Australia, Europe and the US. Oh, they are also mandatory in Western Australia.
Why do RCDs trip?
RCDs are designed to immediately shut off power when they detect an electrical fault. There are 3 different types of electrical faults they may cause an RCD to trip. The first is a power overload and occurs when you turn on too many appliances at once. You might have old appliances that have a high voltage output, or use too many toasters at once-whatever the problem is, we can have a look and fix it for you. Another common fault is a short circuit. This is what occurs if 2 wires touch resulting in a very high current flowing. This is what can cause electrical fires but is prevented with an RCD. Lastly, a ground fault is what happens when a person touches a live wire-electricity travels out of the circuit and enters the ground. An RCD can detect this immediately and shuts off the power potentially saving a life.
How many RCDs do I need?
In Western Australia, each house must have at least 2 RCDs. Having 2 of these devices prevents a complete loss of power during a trip. Imagine sitting in the dark while you wait for a sparky to come and find the fault. As well as dividing half of the electricity load, having multiple RCDs helps with fault finding, meaning the problem can be found and fixed quickly. You can install as many RCDs as you like (within reason), and having one on each individual circuit means the rest of your power continues to run safely in the event of a circuit break. Before a house is even put on the market, the owner is responsible for installing these devices, and landlords must ensure all rental properties comply with regulations for their tenants. An RCD also has to be installed by a licensed electrician, unfortunately a DIY does not comply with current regulations and safety certificates.
Now it isn’t enough to install RCDs and then forget about them. They need to be frequently tested every few months which is as simple as pressing the ‘test’ button. Scott Comms can simply talk you through this on the phone. If you aren’t sure everything is running as it should, we will send one of our licensed residential electrician in Perth out to do a thorough inspection and replacement in a timely manner. If you are building a house, why not get your RCDs fitted at the same time you install your wiring or smoke alarms?
