BASIC CONCEPT OF HOUSE WIRING
www.pgsciencecity.orgMCB: Miniature circuit breaker : It automatically switches off electrical circuit during an abnormal condition or overload of the network. Nowadays we use an MCB in low voltage electrical network instead of a fuse SP-MCB:A Single Pole Breaker is used with a typical 120v circuit, having one hot wire and one neutral wire.
MINIATURE CIRCUIT BREAKER
www.alfanar.comMCB (Miniature Circuit Breaker) is an electromechanical device which protects an electrical circuit from overcurrent and overload conditions. Unlike a fuse, an MCB can be reused after clearing the fault; offering im-proved operational safety and greater convenience without incurring large operating costs.
