Hi, having new hot tub installed, PME supply on 40A breaker 6mm twin clipped direct in loft down to 32A isolator, got some 10mm 2C laying around, and gonna use swa as earth from isolator will that be fine, (thought Iâd ask not sure what these companies are like and Iâm not around when they install so gonna lock off isolator and breaker and leave key for them)
Thanks
Thanks
