Get RCD protected
An RCD can save your life. An RCD is designed to protect against the
risks of electrocution and fire caused by earth faults. For example, if
you cut through the cable when mowing the lawn and accidentally
touched the exposed live wires or a faulty appliance overheats causing
electric current to flow to earth.
It provides a level of protection that ordinary fuses or circuit-breakers cannot
provide. RCDs can also reduce the risk of some electrical-related fires.
How does it work?
An RCD constantly monitors the electric current flowing through one
or more circuits it is used to protect. If it detects electricity flowing
down an unintended path, such as through a person who has touched
a live part, the RCD will switch the electrical circuit off very quickly,
significantly reducing the risk of death or serious injury.
Am I already protected?
If you’re unsure whether your consumer unit already has built-in RCD
protection, look for a ‘T’ test button and label stating ‘test quarterly’.
