What is an RCD plug?
Residual circuit devices (RCD), a device that monitors the flow of electrical current through the live and neutral wires of a circuit. RCDs plugs cut off electricity automatically when activated. They provide higher levels of protection compared to regular fuses and circuit-breakers.
How does an RCD plug work?
RCDs are designed to disconnect the circuit if there is a leakage current. RCDs operate by measuring the current balance between two conductors using a differential current transformer. This measures the difference between current flowing through the live conductor and that returning through the neutral conductor.
Do I need an RCD plug?
It is essential to ensure that any extension lead used outside is protected by an RCD. We would always recommend having an RCD as part of the extension lead unless it is 15m or shorter and you are absolutely certain that any sockets to which it will be connected are already RCD protected.
What is a RCD safety adapter for?
RCD Safety Adaptor Safety RCD adaptor for added protection against the risk of electric shock. It instantly cuts the power in the event of an earth connection leakage. It is non-latching, therefore power needs to be reset at each use and it is ideal for home appliance spike protection.
What needs an RCD?
In domestic properties, situations requiring mandatory RCD protection include: Properties supplied by a TT earthing arrangement (one with a local earth terminal, as opposed to an earth being provided by the distributor). This typically includes rural locations fed by overhead cables.
What causes RCD to trip?
Sometimes your RCD might be switching off its own power, which is known as tripping. It mostly trips when it detects a fault in the electrical circuit. If the RCD is tripping too often it might be mostly because of a damaged appliance. On the brighter side, it confirms that your safety-device is working properly.
When would you use a RCD plug?
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.
When would you use an RCD plug?
What is the difference between a circuit breaker and an RCD?
The difference between a circuit breaker (MCB) and a RCD Its basic function is to interrupt current flow (break the circuit) after a fault is detected. An RCD, which stands for Residual Current Device, is designed for human safety, and can often be life-saving.
Do RCD plugs get warm?
When you install RCD protected sockets, beware that they tend to run warm to the touch, even though nothing is plugged in to them! This is because of their internal sensor mechanism, which draws a small amount of power to operate.
What does RCD mean?
residual current device
An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire.
When would you use an RCD?
What are RCD plugs and what do they do?
RCD Plugs. Residual circuit devices (RCD), monitors the flow of electrical current through the live and neutral wires of a circuit. The primary function of these is to prevent fatal electric shocks for bare wiring. RCDs plugs cut off electricity automatically when activated. They provide higher levels of protection compared to other methods.
When to use masterplug safety in line RCD?
The Masterplug Safety in-line RCD continuously monitors the power supply to an electrical appliance and cuts off the power within 40 milliseconds if an earth current fault is detected. This is fast enough to prevent a fatal electrical shock.

Do you need a fuse for a RCD adaptor?
Sounds like some confusion with the RCD Safety Adaptor (which doesn’t have a fuse), as a replacement plug the regulations require this unit to have a fuse as you have rightly pointed out that it does. 6 of 6 found this answer helpful. Was this helpful?
