whats the deal with them, why do you need such a high powered shower?

Going to do a job this weekend and the customer has already bought the shower. I'm wiring it and a new cu change. Surely this is going to take a 50amp mcb 10800/230= 46.9A will a 10mm T+E manage this located in a wall.

I cannot remember the correction factors from memory but I think that a 10mm T&E will be fine protected by a 50A MCB on an RCD protected board.

You could always run 16mm T&E if you're still worried but I think you would have a nervous breakdown trying to wire the pull cord isolation switch with 16mm ends !. 10mm is fiddly enough !.

Crabtree pullswitch but 10mm should be adequate unless its a mansion or heavily insulated

 
Those crabtree pull switches are brilliant, and so easy to terminate 10mm cable into.
