Stables with horses supply, power & lighting etc..

[Soulsurfer]

Hi all, I have never had to look into a job like this before but I have had an enquiry from a customer who is having a supply brought from the road to edge of his fields / property by the dno and he has to supply cabinet etc.. at a great cost for the mains !

I have to look at a run of around 45 mtrs of s.w.a in a trench to stables, into a small consumer unit at one end of stables where horses will not be but just a storage area. Couple of sockets there adjacent to board, and all light switches there too out the way. They want lighting above the two stables where horses are resident and also floods front and rear outside plus a small sub out to another shed / tack room across the yard around 24 mtrs away. I am thinking a lot of armoured plus maybe a bit of conduit in stables to lights high level etc.. and rcbo cover but would 30mA be alright with livestock ?

Also if board was TT'd with a rod outside away from stables by around 3 mtrs or more is that likely something you would go for ? Only issue I can see is that all around are other fenced fields that have electric fencing so is that likely an issue with the rod and fence earthing rods etc.. ?? never done something like this before.

Also what protection / isolation device at start of mains to the main board?
A time delayed RCD S type at 100mA or similar as thinking just a switch fuse wont be good enough.

Thanks for any experienced thoughts.

Carefully read the regs, it only needs a very small surface voltage to drop a horse. BBC Sport - Horse Racing - Newbury horse deaths caused by electrocution - http://news.bbc.co.uk/sport1/hi/other_sports/horse_racing/9400599.stm

you must remember horse like to shew thing just like a goat .
were are the switches going to be for lighting in general.
have you got a plan.

 

[Soulsurfer]

The switches and socket outlets etc.. would all be in a separate area closed off from horses. You wouldn't believe the state of it at the moment ! Got some pics, flexes hanging next to horses faces all run from a petrol genny. If it's as horrendously difficult as it seems, I may just forget the job to be honest.

this might happen if don't get it wright.

Hi - SS, a few late night thoughts ... I suggest a 100mA S and fuse at the cutout end and a 30mA one up front in the remote board. The rod is important, perhaps use stacked 15mm by 1200mm. I have used two sets indendantly wired as part of reliability etc. Cabling up high, gal conduit. Get them to agree to regular inspection checks cause it will get knocked about.

Thanks chaps, I'm thinking it's beyond me, don't want any horror stories on me. Never as I said done anything like this and it's a bit of a learning curve that I wouldn't want to go wrong.

Cabling up high, gal conduit

SWA cable is best for the job through out the buildings.

 

[Soulsurfer]

It's the rod bit and up front rcd S type and fuse setup that I'm unfamiliar with the most. Bit full on.

did one many moons a go
the dumb a** owners tried to put normal switches with the horses in the stable had to put the switches out side .

 

[buzzlightyear]

and don't for get horse like bright light at night other wise they get spooked.

is the SWA 16mm ?

 

[Soulsurfer]

Would be yes
