Submain, RCD protection.

[Chris86]

Good morning All,

Sorry for posting another sub main question but i have searched various posts and cannot find a definate answer.

I need to install a submain out to a brick built outbuilding which will be used for injured/unwanted ferret rehab. Building has no extraneous conductive parts and main supply is pme.

My plan is 32A rcbo in house consumer unit, 9 metre run of 6mm t&e through floor joists to galv box on outside wall. 6mm 3 core SWA from galv box to outbuilding 11 metre run buried under footpath and them fixed to garden wall. 2 way CU in outbuilding with main switch, 16A supply for sockets and 6A supply for lights. All in galv conduit to make it ferret proof.

My question is, would i be better off having an mcb at the house end and rcd main switch in the sub board? I feel the submain cables would be better having rcd protection but as i can comply with greater than 50mm deep at all points, i am starting to doubt my plan. Any thoughts?

18th Regs, Special locations, Locations which contain (or may forseeably contain) tubular animals or similar.

Whole run in SWA then MCB at the supply end.

A fuse would be better.

This was the reason for my "optimistic",on Tels post...the schemes used to make you cross your fingers and promise to think about maybe trying,for the T&I,but not applying anything which could be cheque-stopping

I think most of the CPS's require some sort of acceptable electrical qualification. At my first assessment, the assessor wasn't interested in my boy scout awards for whittling and/or lying, but was keen to have a look at my dusty apprenticeship indentures and wax seal.

OP, give one of those schemes a bell and ask. All I would say, when I decided it might be a fun idea, and do some sparkying in my semi-retirement, I went and did a 2391. Money well spent, as I never previously seen any test equipment, other than a Drummond Test Lamp.

Thanks to all for your advice and input. All this talk of schemes has got me thinking. It may be worth a go, who knows what the future holds and maintenance in the motor industry isn't exactly secure at the moment. I will definately be looking to do the 2391 this year if a can find a way of working it round family and shifts.

With regards to the housing of the ferrets, they plan to have 2 indoor bed areas within the outbuilding with holes knocked through to outdoor runs. There will also be an indoor pen with a covered play pen style run and them some smaller hutches to act as sick bays. The sockets will mostly be located by the hutches for running heat lamps/beds (max 2) . No sockets will be located within any of the actual pens. They have certainly thought the layout through and know exactly what they need.

Thanks again.

Bizarre, that's exactly what caused me to quit the industry in 1984.

Train a ferret well and you'll have no need for any rods......or an apprentice, come to think of it.
