Provided with three neutral bars which in significance offers three financial institutions of circuits to offer the best of both worlds; enabling for making use of RCBO's as well as 2 banks of Mini Circuit Breakers (MCB's) they use total crucial circuit separation and very economical security for conventional circuits. They are increasingly preferred because they make circuit style simple and also are economical.

Getting The Consumer Unit To Work

They provide no circuit splitting up indicating a recurring fault on any circuit will certainly knock-out the power to all other circuits, they are for that reason practically never made use of in a major residence.
