That suggests that a residual existing fault on any circuit will knock out power to all other circuits (Consumer Unit). Therefore, they are virtually never made use of generally house.


All four kinds of consumer device are most typically supplied in this style. They usually constantly include a front cover hinged on top, to ensure that it closes via gravity when not being serviced, thus guaranteeing it is always shut.

Provided with 3 neutral bars which fundamentally provides three banks of circuits to supply the most effective of both worlds; enabling making use of RCBO's and also 2 banks of Mini Circuit page Breakers (MCB's) they use overall crucial circuit separation as well as highly economical protection for common circuits. They are increasingly prominent since they make circuit design simple and also are economical.

Some Ideas on Consumer Unit You Should Know
