Hello All,
I've looked at the faq, but still not sure, apologies in advance then if this is well covered
I'm hoping to get an electric shower in over the bath, and would like to know what it's going to take, (apart from water,10mm2 cable,supplementary bonding, 50 amp pull-switch,and rcd csu ) I'm in Scotland, in a 25 year old house, with a meter in a cupboard outside, the consumer fuse is 100 amp, 6.5mm o.d tails (20mm2 ?),to a meter ( type C11B3a-h, 20-80 amp, 230 volt), then there is an approx. 10 metre run of cable 20x10 o.d, 6.5mm o.d on the wires inside,(20mm2 ?) to an original (vintage) Wylex 8 way 60 amp fuse box in a cupboard at the foot of the stairs. Everything is in good condition and working at present (except me, who is a bit cream crackered) Bathroom upstairs, would be approx. 12 meter cable run through the loft, down through a cupboard, a floor and into the csu cupboard or about 10 metre run to the meter box.
If I were to get a 9.5kw shower:
1. Would I need to get a new meter put in?
2.What would be the highest kw shower with existing set up?
3. What amps for the csu ? 80, 100, I would like a bit of spare capacity for future needs if possible.
4. Do I need to upgrade cable from the meter to the site of the Wylex, if a new csu were to go there?
5.Alternatively, could a shower csu be put in, in the meter cupboard, ie a separate circuit leaving the Wylex in place?
6. A handy run for the cable, if it were ok to have a shower csu in the meter box, would be through the boxed off corner of the kitchen and up to the bathroom, then into the loft, not trunking, just 2 x 2 and plywood, about 150mm x 300mm, where the water pipes and the soil pipe are, plenty of room, not right up to the pipes, airy, only insulation is on the pipes, is sharing a route permissible if no interference is caused to other services?
7. If the cable goes through oval trunking, (like through the cupboards),would 10mm2 be ok, does it have to be uprated ?
I want the job done safely and properly, but am a bit on the skint side, do you sparkies have to do the whole thing, supply the gear, drill the holes, bang the nails, write the theme tune? I would like to do whatever work, if anything, is acceptable in order to have a smaller bill. Is it ok to have some planning and preparation, laying out of cable, done in advance, if you can see it all, and it's done the way you would?
All advice gratefully received,
regards Jim
