hi
as per title.. is this safe?
its on a 10mm² cable laid across loft on top of insulation, approx 8m run (1m from shower to 45a isolator switch, then 7m from switch to c.u). I know it should be on a 45a mcb, but it's not. never had a problem with it tripping etc.
shall I replace to 40a mcb with a 50a (they don't make a 45a for my unit)? if I put a 50a mcb in do I need to change the 45a isolator switch to 50a too?
many thanks
