With the 63 amp rcd boards with 6 amp and 32 amp breakers in for a garage I was going to put in a 4mm twin fed of the house board off a 32amp breaker as the current carrying capacity of 4mm is 37 amps.What does every one else use as a rule ?
Attached to the houseDare I ask...is it an attached garage or will you be supplying your own earth?
I do wish my wife would come in and mke my tea, rather than spend all evening welding in the garage............jobs end with 'wife wants to put freezer/tumble dryer/caravan hook up/mig welder in the garage .......'
