Consumer unit. R.C.D. protected shower circuit supplied by a B40 M.C.B. which runs to a cord ceiling switch  in the shower room in 6.0mm2 T&E. Old electric shower removed. New power shower installed with water supplied from tanks. 0.63 Amp transformer in loft to feed new integral shower pump motor. Loft transformer fed via 3 Amp fused switched fused connection unit on a 1.0mm2 T&E cable from old shower ceiling cord switch. 1.0 mm2 T&E run 2.5 metres.


P.S. The switched fused connection unit is at the end of the supply cables.


Confirmation or condemnation by regs. please.

    Even though the power shower should be fed via a double pole isolator, the isolator should not be used during normal operation. It should be permanently connected in order for a controlled shut down to take place. The cord switch invites incorrect operation. 




    I expect that the plumber installer will discuss operation with the customers Foffer, and leave the user's instructions with them as well.
