Or an RCD for short. These are designed to prevent you from receiving a fatal electric shock, should you touch something live like a bare wire.
As well as potentially saving your life, an RCD can also provide some protection against electrical fires. RCDs give a level of personal protection that ordinary fuses and circuit-breakers can't offer. As such, there are a few different types of RCDs that you can use..
Fixed RCDs
As you'd expect, a fixed RCD provides the highest level of protection as it protects every socket on a circuit, as well as the wiring, including any connected appliances. Fixed RCDs are 97% reliable.
Socket-Outlet RCDs
These special socket-outlets have an RCD built into them. Please note, this type of RCD will only protect the person in contact with the equipment that's plugged into the RCD socket-outlet.
Portable RCDs
These will plug into any standard socket-outlet, and in turn, you can then plug the appliance into the portable RCD. Again, these portable RCDs will only protect the person in contact with the equipment that's connected into the RCD socket-outlet.
How much do they cost?
You can purchase a plug-in RCD for as little as £10, if you're after a fixed one, they'll naturally cost more.To ensure your whole family are safe, we can install a fixed RCD for you. Contact us for a quote.
