WebResidual Current Circuit Breaker (RCBO) with overload protection (BS EN 61009) 2) Socket-Outlet RCD’s feature built-in residual current devices and can be used instead of traditional socket-outlets (BS 7288) 3) Portable RCD’s plug into any standard socket-outlet, allowing electrical appliances to be connected directly to the RCD (BS 7071) WebFirstly fuses and MCBs – that is miniature circuit breakers – they both ‘blow’ when current is exceeded, but an MCB can be reset after the fault is fixed, a fuse must be replaced. A fuse is basically a piece of wire between two contacts to make a circuit. When current flows heat is produced and the wire gets hot.
WebType A RCDs trips from AC currents and DC pulsating currents and are now the new standard but a AC type RCD is perfectly suitable to cover a combi boiler. ... If i was replacing a fuseboard, I would install type A Rcbos and a surge protection device to all circuits to fully comply with current regs.
