MCB Rating
 

A friend has a plumber fitting a (pumped) Power Shower in place of an
electric
shower.

The plumber is going to use the existing electric shower wiring (mostly) and
will down rate the MCB. The instructions for the Power Shower recommend a 3
amp fuse. For his Consumer Unit it appears that 6 amp is the lowest rating.
With motor surge in mind - does this seem correct anyway?


Regards

John

He needs to put a fused connector unit in, with a 3A fuse. Ideally,
adjacent to the pump, or nearby in an easily accessible place.
It has local isolation then.
