BASIC CONCEPT OF HOUSE WIRING

MCB: 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.
