An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations to prevent shock. It consists of either a current sensing mechanism, or a voltage sensing mechanism. Such a protection mechanism may be found in the form of distribution board modules, standalone devices, and special sockets (aka receptacles ).
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
RCDs tripping due to split elements of fixed appliances does not in reality give any added safety, thus is more correctly described as a nuisance trip. I realise this may sound counterintuitive, but bear in mind safety is removal of danger, and danger equals number of deaths, and split immersion elements are simply a non issue from a safety POV.
The grounding system must also have a minimum of two or more earth pits (electrodes) to better ensure proper grounding. According to rule 42, an installation with a connected load above 5 kW exceeding 250 V shall have a suitable earth leakage protective device to isolate the load in case of earth fault or leakage.

A ground fault (earth fault) is any failure that allows unintended connection of power circuit conductors with the earth. [citation needed] Such faults can cause objectionable circulating currents, or may energize the housings of equipment at a dangerous voltage. Some special power distribution systems may be designed to tolerate a single ...
A separate study conducted in part by the Male Contraceptive Initiative, showed that before the abortion ruling, 78% of men in the U.S. said they were interested in trying new birth control ...
UNC coach Hubert Davis, forward Harrison Ingram incensed after Duke star Kyle Filipowski appeared to trip Ingram after they got tangled in the first half of Saturday’s game at Cameron Indoor ...
An automatic trip is an action performed by some system, usually a safety instrumented system, programmable logic controller, or distributed control system, to put an industrial process into a safe state. It is triggered by some parameter going into a pre-determined unsafe state.
