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.

    The easy fix is to avoid questions about the length of cable before the 3A fuse, is to change  the 40A breaker for something smaller - for a 3A fuse, almost anything would do, 6A, 10A 16A - whatever is available .



    If "supplied from tanks" (my emphasis) in the OP means that the new shower unit does not heat the water, this is the obvious solution; but why not simply reposition the FCU?
