Right had the box off the wall again this morning, the switch was getting quite hot during use and there was a strange fishy smell which I can only assume is melting insulation.
The shower is 8.7-9.5 kW
The switch is 45amp DP
and its MCB says 63amp on it so assume that's maximum load.
The cable is 6mm
Does this sound ok?
Im gonna change the switch and backbox out today and redress the burnt cables. Hopefully solve the issue,
