Electrical Mcb Wiring Diagram. Electrical wiring in a residential house is not that complicated but it can be dangerous. Mcb is used in low to medium voltage and current carrying electrical circuits.
Mcb is a mechanical switching device which can carry and break currents under normal circuit conditions and also under specified abnormal conditions such as overload and short circuit. In the diagram is shown the method of wiring distribution mainboard form utility pole to energy meter and then dp circuit breaker and sp mcb breaker. Miniature circuit breaker sizing electrical engineering centre.
There are 4 main kinds of circuit breakers in a common household.
I hope this post helps you to understand the connection and method of wiring an rcd or rccb. There are many electrical engineering students and many other people who work in electrical wiring have some confusion about the selection of rating of circuit breakers and also the connection of rccb and mcb. In the rccb wiring diagram a single phase kwh energy meter connection shown with double pole mcb and rccb to load. A five pin socket is placed in the switchboard to connect the external temporary load.
