I have a 8 year old crabtree consumer unit, do I need to purchase a circuit breaker or can my electrican run a 10mm cable from the unit and fit 45amp shower switch outside the bathroom? View media item 35142
Thanks 'sparkybird' for your reply. Wanted to know what type of breaker do I need that would go with this unit, can I get it from likes of B&Q and fit near the empty slot in RCD on the right handside?
My electrian told me to get the parts and he would fit it.
If it's a split board with only one side protected by a RCD, you could do it either way.
MCB RCD side
or RCBO non protected side.
MCB will cost you about £4
RCBO £25-30
