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.
Earth fault protection also requires current transformers and senses an imbalance in a three-phase circuit. Normally the three phase currents are in balance, i.e. roughly equal in magnitude. If one or two phases become connected to earth via a low impedance path, their magnitudes will increase dramatically, as will current imbalance.
The incoming protective earth/neutral conductor is connected to a neutral bar (located on the customer's side of the electricity meter's neutral connection) which is then connected via the customer's MEN link to the earth bar – beyond this point, the protective earth and neutral conductors are separate.
Also at the Boston conference on Sunday, YourChoice Therapeutics said a very small trial in the U.K. — just 16 men — showed that its nonhormonal pill, YCT-529, was safe and free of side effects.

Food left out for household pets is often equally attractive to some wildlife species. In these situations, the wildlife have suitable food and habitat and may become a nuisance. [3] The Humane Society of the United States (HSUS) provides strategies for the control of species such as bats, bears, chipmunks, coyotes, deer, mice, racoons and ...
