Shower Pump

[m4tty]

Hi,

Got a job coming up and had a brief look at it. Its wiring a shower pump which will be in the loft. Only place I can see to spur off is immersion heater circuit which has already been spurred for c/h. Is this ok? Its a 16A Radial cct so cant see spurring being a problem other than the arguement saying immersion should be on its own circuit. All wiring will be surface in the airing cupboard and clipped direct in loft.

If im altering the immersion heater circuit will it need an RCBO or as my wiring is surface can I get away without adding one?

Thanks in advance

regs state water heaters (over 20ltr IIRC?) must be on their own circuit. so you cant take it from there

but you may be able to use lighting circuit. they dont use much power

Matt,

a water heater should have it's own circuit as you say, however I'd have no problem spurring off it as you suggest, I wouldn't RCD the circuit if it's surface wiring.

the water pump might specify it needs RCD protection, looks at instructions, while back i fitted one and it said fit one, remember your mixing water with electrics

also i would come off immersion heater because pumps dont use much current at all, although regs do say otherwise you've got to be practical if theres no sockets nearby. I personally wouldnt like putting pump on with lights unless small circuit
