RCD’s (Residual Current Devices) or safety switches are designed to cut the power in a fraction of a second in the event of a fault. These life saving devices are not to be confused with circuit breakers, which are in place in most homes but do not protect against electrocution.
Whether you’re doing some home renovations or simply using a household appliance at least 15 Australians are killed each year in preventable home electrical accidents and many more are hospitalised.
There are 4 main types of RCD’s:
- Meter box mounted
These must be installed by a licensed electrician and are generally located alongside circuit breakers in the main meter box or distribution board of the property.
- Combination RCD Safety Switches and Circuit Breakers
These are great for new builds as they save space in the meter box. Again these are to be installed by a licensed electrician.
- Portable RCD’s
These can be purchased from an electronics store and attach to a power board or extension lead and only protect the circuits of appliances connected to them.
- Power Point RCD’s
Are fitted to a power point and can be distinguished by the test button on the face plate. They must be fitted to the first power point after the meter box.
It is a law for all houses built after 2000 to have a minimum of two safety switches installed at the main meter box or distribution board. However, between 1992 and 1999 houses only had one RCD installed which will not ensure complete protection for your family.
RCD safety switches can be recognised by the test button on front of the device and it is recommended that all RCD’s are tested every three months.
