Rating for Shower Isolation Switch

[Traveller]

Thanks, I had not found the Click Scolmore item - could be good.

The manufacturers instructions for the shower state that a separate circuit must be used back to the CU and since one is already there........... The instructions also specify an isolation switch must be fitted. Maybe the best solution is just to buy a 3amp MCB for the CU.

never ever seen a shower pump on it's own circuit. always fed from nearest available point on socket circuit, fused down 3A or 5A FCU.

I think the circuit was probably originally put in for an instatnt head electric shower which would obviously have drawn a lot more current.

I think the dedicated circuit was installed for an earlier instant heat electric shower - hence the need for higher current etc. I guess the best thing to do now is to install a 3amp MCB in place of the existing 32amp one.

So what size cable is currently wired to the shower circuit?
