[QUOTE="AttitudeAllStar, post: 555226, member: 37890"] Thanks Murdoch, I'm thinking the same. Would I be right in thinking should both hob and oven draw their maximum power, the 6mm cable will tolerate it ok all the way back to the MCB; and at their maximum, the 45A FCU shouldn't be affected (unless there's a fault), however, if attempting to draw above a total of 32 Amps, the 32A MCB would trip? So with diversity in mind, all should be ok. And if in the future there is nuisance tripping, I could ask the electrician to up it to a 40 or 45A MCB or probably RCBO. Can't believe I thought a 13A FCU was needed for the hob. [/QUOTE]
