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.

    Hello Chris,

                          the fused connection unit can not be re-positioned next to the shower cord switch as it is inaccessible above, and the customer does not want it in the shower room.  The fused connection unit is next to the shower transformer in the loft at the end of a 2.5m length of 1.0m2 T&E fed from the shower switch which is fused at 40 Amp. The consumer unit is inaccessible. to work on. You are correct, the new shower gets it water from tanks and does not contain a heating element. The transformer is only a 0.63 Amp load and is fused at 3 Amp so can not overload the 1.0mm2 T&E. Also a short is virtually impossible on the 1.0mm2 T&E as it is out of reach in the loft. The circuit is 30mA R.C.D. protected as well. The shower pump is E.L.V., but that is not my concern.
