Wiring Diagram Mcb. If the circuit was originally a ring main but this has become broken and is now a spur or radial main then it could be fed with 25mm and 32 amp fuse. Show activity on this post.
However we study all step by step distribution board wiring below as we talking about the. An mccb with 4 poles also can be used and the utility neutral then first needs to be connected to the bottom side extreme right. According to the wiring diagram 2p dc mcb has two wiring methods one is the top is connected to the positive and negative poles another method is the bottom is connected to the.
Mcb means miniature circuit breaker.
In the below diagram a double pole mcb circuit breaker wire with a fixed 2 pole rccb. Main switch main switch plus the use of rcbos for every circuit 2. The installation of rcd is too simple in single phase wiring mainboard. Mcb is a protective device which protects the electrical circuit as well as loads from short circuit and overload faults.
