Shepherds hut electrics

[ericmark]

Essentially it is no different to any other preassembled electrical device, such as View attachment 279300

So the shepards hut is same idea but bigger?

Surely it would follow the same regs as a caravan? In which case any competent caravan/motorhome repairer or constructor could arrange for the appropriate testing and certification. I am surprised you’ve not been asked for it before.

Lots of these guys come to site so you just need to find one near you who can install , test and issue the relevant paperwork or is prepared to check your work, test and issue paperwork.

It may be a business sideline but you really need to get to grips with the relevant business regs and ensure compliance otherwise in the event of a fire or electrical incident you could be on dodgy ground.

Isn’t there a caravan builders council or some such that could be approached for guidance?

Is it supplied complete or in parts to be assembled on site?

You may want to look into making it so each part can be plugged into the other.

We haven't built many yet, covid messed things up, The electrician we were using is off sick and will not return to work full time, so we don't think he'll renew any scheme membership (can't remember who he was with)
But from what has been mentioned on here, doing live testing in our workshop and issuing an EIC might not be the best way to do it

You might want to look at BS7909.. it's primarily aimed at the entertainment industry but it covers things like mobile catering wagons, concessions stands, etc. and puts a lot of emphasis on "pre tested assemblies" It might not be legally applicable to your situation but you'll probably find some of the information relevant.

3 Years since I started this thread, we've built another couple of huts and been using another electrician who's been doing tests on our site and providing an EIC (I think) but stating on it that the test results only apply on our site and it will need new tests when installed in it's new location.
But sadly this electrician is now off work ill, (his last visit he was connected to a small oxygen cylinder) he's hopefully back at work sometime early December.
We are part way through building another hut, with first fix all done, this one has a shower room with an electric shower, it also has an electric towel radiator, and a light, so 3 separate circuits all on rcbo's, we are wanting to finish the shower room fittings etc and are wondering if any supplementary bonding would be needed, before boxing in pipework etc, from my limited research is it going to depend on disconnect times, which we will only know when he is able to do some testing. Would it be worth routing some bonding cables just incase they are needed.
Electrician hasn't answered my last text message and don't want to bother him too much at the moment, but would like to be able to continue with the build. Thanks for any advice.

Why not let the customer be responsible for fitting the electrics?

 

[securespark]

Surely better done during the construction stage?

The disconnection under fault conditions is reliant in the main on the RCD, it is unlikely that the loop impedance will be low enough to use any other method. Also, it is very hard to ensure a supply is TN-S, we have to consider any TN supply is TN-C-S which is not permitted with caravans. So in real terms it has to be a TT supply.

I have never had an EIC or EICR issued when buying a caravan. Can't really see the point, as once moved, it would be invalid.

 

[flameport]

if any supplementary bonding would be needed,

It won't be.

iv - All the circuits will comply with disconnection times (if not then there are severe problems which no amount of supplementary bonding will fix)
v - All the circuits have RCD protection (from the RCBOs)
vi - It's a hut, extraneous parts not found unless for some inexplicable reason you have used metal pipework throughout and you didn't bother to install bonding from that to the main earth terminal.

I thought Part P was part of the building regulations so if not a building nothing to do with them.

I have heard that same principle applied to the Electricty at work regulations, yet those regulations only say "You must" or "you must not" they do not say "At work, you must" or "At work, you must not", thus they do not apply only at work but everywhere else too.

also every domestic dwelling or public place can become a place of work once you employ a decorator or a plumber or a joiner to work on your property therefore that potential of it becomming one is ever present.

Just as years ago a "Factory Inspector" (as we called them) could take someone to task for using "dangerous methods" in places where the public had access - nowadays we might call those factory inspectors "The H & S executive" .

How often do we hear the phrase "An Englishmans Home is His Castle!"?
No it is not - It never was!

Actually it does say "at work".

Persons on whom duties are imposed by these Regulations​

(2) It shall be the duty of every employee while at work

This removes the need to say "at work you must".

The Electricity at Work Regulations 1989

These Regulations impose health and safety requirements with respect to electricity at work.

Why not let the customer be responsible for fitting the electrics?

We build them from the inside out, like they do with motorhomes, so cable runs etc aren't really accessible when built

Ok thank you. The hut is built on a steel chassis, then wooden floor joists, then the main "hut" no part of the "hut" is connected to the metal chassis, main water supply is plastic with some copper internally in the hut, no gas or oil pipes involved with this one.

Shepherds huts, we have an order for a new hut that will have some electrics, couple of sockets, couple of lights, small consumer unit with RCD

Not exactly nativity style is it?
