RCDs - A Complete Guide to Residual Current Devices - RS …
Jan 30, 2023 · An RCD is a life-saving device designed to detect leakage current. In the event of detection, the device automatically disconnects the circuits being monitored. This helps to prevent the risk of a fire or electric shock.
What is RCD Testing? | RS - RS Components
Jun 16, 2023 · RCD testing is the process of checking that the RCD installed in a circuit works correctly. It can also help electricians or circuit builders identify when an incorrect RCD type has been used. RCD testing can be completed using the test button on an appliance or fuse box.
A Guide to RCBOs (Residual Current Circuit Breakers) - RS …
Aug 29, 2023 · An RCD device complete with overcurrent protection is called an RCBO, or residual current circuit breaker with overcurrent protection. The primary functions of RCBOs are to ensure protection against earth fault currents, overload, and short circuit currents.
Fused Spurs Buying Guide - Types and Applications - RS …
Aug 29, 2023 · Fused spurs are not to be confused with residual current device (RCD) sockets, which are built to automatically switch off live current. By doing this, RCB sockets can protect anyone in contact with a device from electrocution in the event of a fault or short circuit (the flow of electrical current into a circuit with insufficient resistance).
A Complete Guide to Distribution Boards - RS Components
Jan 30, 2023 · What is an RCD, where are they used, and how do they work? Discover all you need to know about residual current devices in our comprehensive RCD guide.
RCD Sockets | RS - RS Components
RCD sockets (residual current device) are designed to protect from fatal electric shocks as it automatically switches off electricity when there is a fault. This potentially life-saving device protects against electrocution in instances where there is a bare wire, overheating or earth faults.
PAT Testing Requirements & Equipment - Complete Guide - RS …
Jan 30, 2023 · Reviewed by Jay Proctor, Technical Support Team Leader (August 2021) Ahead of any PAT testing, find out more about the PAT testing equipment you will need to use, including information on which PAT tester will be best suited to the task at hand.
RCCBs | Residual Current Circuit Breakers | RS - RS Components
An RCCB or residual-current circuit breaker is a safety device used to protect electrical circuits. RCCBs protect people from electric shocks, and electrocution and help prevent electrical fires. RS offers an extensive range of high-performance RCCBs and RCDs from leading brands including ABB, Schneider Electric, and Siemens.
Residential Circuit Breakers | Type B RCBO | RS - RS Components
RCBO stands for Residual Current Circuit Breaker with Over Current. RCBOs combine the two main functions of an MCB and an RCD. They are a type of circuit protection device designed to disconnect a circuit when a current becomes unbalanced. Therefore, protecting both …
RCD Plugs | RCD Multi Plugs | Inline RCD | RS - RS Components
An RCD essentially is a safety device that switches off electricity automatically if there is a fault. So for example, if you cut through the cable and expose live wires or a faulty appliance overheats causing electric current to flow to earth.
