RCD Safety Switches
What is an RCD?
An Residual Current Device (RCD) is a sensitive safety device that automatically switches off electricity if a fault is detected. The safety switch provides protection for you, your family and business from injury or death caused by electrocution and fire started by an earth fault. Simple everyday activities such as drilling holes to put up shelving into a wall or using an electrical appliance can turn deadly without the protection of an RCD Safety Switch.
RCD Safety Switches are required by law to be fitted at the origin of the power and lighting circuits. This is the main meter box or distribution board for the residence or business.
Since 2000 it has been compulsory for all new homes to have a minimum of two RCD Safety Switches fitted to protect the power and lighting circuits as part of the electrical installation. However, homes built before 2000 were not required to have two RCDs fitted and from 1992 to 1999 only one RCD was fitted. This does not ensure complete protection.
What happens if my RCD keeps tripping?
This is called nuisance tripping. In most cases it concerns appliances or situations that involve at least one or a combination of three conditions, all of which requires a licensed electrician to rectify.
• Moisture causing electricity to leak to earth in an appliance or within premises wiring.
• A heating element that is either faulty or drawing sudden electrical surges.
• An appliance with an electric motor that is either faulty or drawing sudden electrical surges.
If you find that your home or office is nuisance tripping, give us a call on 1300 041 784 and we will come out to see what is going on and if necessary replace them.
RCD’s need regular testing.
All RCDs can be identified by the test button on the front of the device which you should test regularly. Belenus Pty Ltd recommends that you test it every three months. We will remind you to check your RCDs. By signing up to receive regular emails from Belenus Pty Ltd we will remind you to check not only your RCDs but your smoke alarms, solar panels and energy bills.
If you are unsure whether you have RCD Safety Switches installed, their adequacy or it is tripping contact us on 1300 041 784 or email us. We will send a Qualified Electrician around to check, supply and fit your RCDs. They will also show you how to regularly test them.
