I've decided to get an Aqualisa Quartz shower. The pump/control unit needs 3A, and will physically be located in the loft.
Considering that i'm part way through my DIY rewire and therefore my options are open, what would be the best way to hook this up:-
1. New, dedicated 6A radial from CU, 3A FCU next to pump/control
2. 3A FCU spur off upstairs lighting circuit
3. 3A FCU spur off upstairs ring.
I'm thinking 2 is a bad idea really, since if the shower draws 3A then that halves the capacity of the lighting circuit.
(3) is probably easiest. If I spur off the back of a socket, must the spur be in 2.5mm at least until it reaches the FCU? or can it be in 1.0 or 1.5 ?
Second question, will the shower need adding to the supplementary bonding? the mains voltage is contained in the loft, but the buttons (which are low voltage, but prewired) are clearly in the shower area. Therefore they must be SELV, and the only mains is not in the bathroom. I'm thinking that it doesn't need bonding, but would appreciate the advice of experts.
Thanks
