Residual current devices (RCDs) ensure automatic disconnection of supply in low voltage systems especially if the impedance of the fault limits the current to a value that is below the overcurrent protection threshold.

The tips range from the relatively simple, such as not lighting a barbecue indoors, to the workings of a residual current device in an electric socket.
For instance, protect yourself from electrocution by always using a Residual Current Device (RCD) when operating electrically powered garden tools and mowers.
Remove the following conditions from the licence: Annex 2 Where electrical equipment is temporarily brought into the premises as part of the provision for the conducting of regulated entertainment under the licence, any power circuit used as a means of supplying power to the said equipment shall be provided with a residual current device designed to trip at not more than 30mA.
The majority of electrical fires could be prevented by fitting a Residual Current Device (RCD) but worryingly the same figures suggest that 52 per cent of all private rented homes fail to have adequate RCD protection at the consumer unit.
Any used electrical appliances introduced by the landlord should be PAT tested.Ideally the electrical system should be brought up to Electrical Regulation standard, with a RCD (Residual Current Device) fitted at the consumer unit.
Consider using a residual current device which protects against electrical shocks and reduces the risks of electrical fires.
If you're using corded power tools outside or in damp conditions, play safe and use a residual current device or power breaker, which will automatically cut off the electricity if an accident happens or the tool malfunctions.
"The residual current device is a safety device that switches off electricity automatically if there is a fault.
always plug the cable into an Residual Current Device (RCD) circuit-breaker
* Check your power tool is connected to a residual current device (RCD).
