Household Circuit Fuse Box

Latest fuse boards consumer units contain rcd protection devices which trip the supply on a detected earth fault at 30 milliamps in milli secounds thus reducing as much as possible the chance of fatal shock. Household circuits circuits in houses are generally wired in parallel which allows you to operate each light or power point independently of the others. Rather if they are in circuit before a rewirable ceramic fuse or cartridge fuse it is highly likely that the fuse will not be blown away avoiding hassle.

Fuses may be found in place of circuit breakers rewirable fuses have a piece of special fuse wire running between two screws. This also means the current running through any one section of the parallel circuit stays small enough to prevent problems because in parallel circuits the current is split up and travels along each separate path.

Both mcb and any fuse needs checking of the fault in circuit or line before reactivating them. Domestic consumer units receive the main electrical supply and distribute it to individual circuits throughout the home to provide electricity. The fuse box will then be disconnected by taking the lid off the top unscrewing the fuses unhooking the wires and removing the fuse box off the wall.
