Ive been called in to check and repair some electrics in a large domestic garage/workshop that keep tripping, but I've been confronted with a CU that's at least 3m ffl (it's a high ceiling with open rafters). As I've got to test everything in the CU, I'm highly tempted to recommend to move it to an accessible level. It'll probably save me time in the long run, rather than going up and down a ladder! What would you do?
