RCD Full Form

What is the full form of RCD?

The full form of RCD is "Residual Current Device." It is a standard life-saving device that is designed to prevent a person from getting a fatal electric shock if one touches something live, such as a naked wire. The main function of RCD is to disconnect the electric circuit in case of a leakage current. The working mechanism of an RCD is to quickly and securely disconnect the conductors of electricity ("trip") so as not to cause serious bodily harm or damage to electrical equipment. It is also helpful for some protection against electrical fire incidents. RCDs are considered better than ordinary fuses and Circuit-breakers as they provide a higher level of personal safety.

Working of RCD

As it is used to protect one or more circuits, an RCD continuously monitors the flow of electric current through the circuits it is involved in protecting. The RCD has the ability to detect electricity flowing down an unintentional path, such as through the hands of someone who has touched a live part. In this case, it will immediately switch off the circuit in order to prevent any serious injury or even death.

RCD Types

RCDs are extremely helpful in protecting from electric shock in areas such as bathrooms and gardens that are potentially dangerous, and there are different types of RCDs that are used to ensure the safety of respective places like Fixed RCDs, Socket-Outlet RCDs, Portable RCDs.
