TYPE B, C etc RCBOs...
Discussion
I'm redoing my bathroom currently and got an electrician to fit spotligts last week. He upgraded an MCB to a type B RCBO on the fusebox and my dads just been looking over teh place and tells me that it should be fitted wiht a TYPE C
The guy I used was part P and has certified the work so I'm sure he's correct but my dads renovated a lot of places and is sure he's.
Who's right?

RCBO'S used to only be available with a type C characteristic (an RCBO is combined MCB+RCD).
Type C MCB's are common for lighting as the load may be inductive (fluorescent lamps, ELV incandescent & LED).
It depends upon the number of lamps & the load on the circuit.
What was the original MCB rating & type?

Type B is general use and the norm for domestic, but either are suitable.
I've used type C's where you have lots of fluorescent lighting or GU10 downlights as the surge at switch-on can knock a type B out. Type C's are also less likely to trip when a lamp fails, but if there's a dimmer in circuit a type B is far more likely trip in time to protect it.
