Wiring 6kw generator 3 pin sockets to domestic sockets?

[Richard Knight]

Just bought this generator Villiers V6000ES 6kW Silent Petrol Generator - Villiers from pump.co.uk - W.Robinson & Sons (Ec) Ltd UK


For use on a construction site and to occasionally power the caravan on.


It has two 110v sockets and one 240v 32 amp socket. it's the 240v socket that I will be using as all my tools run off 240v.


Firstly I think I need to ground the generator, is that correct? I have purchased a 4 ft copper grounding rod.


On the generator there is one 32 amp socket - how do I safely wire this to convert it to domestic sockets.


I have found a 16 amp version 1 METRE GENERATOR FLY LEAD 16 amp PLUG TO 13 amp TWIN SOCKET 1m | eBay but not a 32 amp version.


Do I have to purchase a 32 amp to 16 amp splitter Camping Electric Hook Up Cable Caravan Boats 3 way splitter 32a to 2x 16a | eBay I'm guessing these have some sort of transformer?


Or can I just wire a 4 gang switched socket strip onto the 32 amp sockets...my common sense says that's not safe as sockets should be 13 amp. What size cable would be best also?


Thankyou!

You don't need an earth rod. You don't need a transformer. Just because the generator socket is 32A does not mean you have to draw 32A from it. Put a 13A socket on the end of it.

Thanks

Should I get fused sockets or will just normal ones be fine?

Why is there earthing connections on the generator then if it doesn't need earthing?

For your sake and the safety of others, get an electrician to look at the job for you.

Your crystal ball is obviously working better than mine if you can tell for absolute certain that an earth rod isn't needed without assessing the situation in person and properly.

Best remind yourself, not to work on generator installations, unless it's with those piddly little 2 to 3KW jobbies, that will almost certainly have a floating earth arrangement!!

Had you looked at the link in the OP you would have seen that 13A sockets are not suitable. I would definitely use an earth rod.

Thanks, we have wired up properties before and we always get a qualified electrician to check all the work and it always passes. We have an electrical engineer coming to the site shortly who we will get to check what we have wired up.

I emailed the guy who sold be the generator and he told me to just wire a 4 gang socket onto the 32 amp plug provide. Is that ok? What size cable is best?

Without knowing how it's been wired by the manufacturers, with regards to earthing arrangement no-one can tell you for sure. If there is a N-E (Frame) connection, then you will almost certainly need an earth rod. Do you have a manufacturers Schematic wiring diagram, if not you may be able to find one for your model on the manufacturers web site.

One more thing, ...if the generator does not have a AVR or other form of automatic voltage regulation, i wouldn't be using it to supply your caravan, the fluctuation of voltage and frequency can potentially take out your electronic appliances/audio-video equipment that you may have. Small generators without voltage regulation are primarily for use on building sites etc, basically to supply power tools and lighting etc...

We have the earthing rod so it can't hurt even if it doesn't need it. But it has an earthing point on the generator so it looks like it needs one.

Yes the generator is AVR regulated, do you think its sensible charging things like my iphone and ipad using the sockets in the caravan when the caravan is running off the generator. Would hate to fry them!

Hi sir,
I don't want to seem a plank but is that why the generator is "not suitable for wiring into a domestic supply" ?

Cheers

The main reason is the generator output is centre tapped so all subsequent protective devices and switching should be double pole. Which is why BS1363 plugs and sockets aren't suitable.

Without an AVR there is a distinct possibility of damage to any electronic equipment.

The generator has an AVR device fitted.

I think we need to be a bit clearer when we say this generator is not suitable for use as a domestic supply.

The arrangement of this generator's windings will be V-0-V, completely and utterly unsuitable for anything other than site tools or lighting, and I'd hazard a guess that the winding's center tap isn't bonded to the frame, but without looking at the schematics I can't say for sure on here.

Personally, assuming no frame bond, I wouldn't rod it and would restrict anyone from plugging anything into it that isn't class 2, but then I have no idea what this construction site you're on is like and whether the generator's use can be adequately supervised?

As others have said, you need an electrician, competent in the application of generators, to determine the best safety measures for your situation.
