Hi all, I was wondering if anybody would have any idea how much it would cost to have a 32Amp socket installed next to my existing house fuse box?

I am then planning on running a 6mm HO7 rubber cable extension cable to my garden to power my control panel when and as it's in use.

Probably best to get somebody out to quote.

It will depend on if you already have a spare way in your consumer unit which can be used. Also, bearing in mind it's intended use in the garden, it will need to be protected with an RCD. Whatever, it will all come under Part P work and so will have to be done by a qualified electrician, so you may as well get a couple of quotes to be sure.

Sorry I can't be more specific. Just in my experience the cost of a job can vary considerably from a guesstimate, when a qualified sparks takes a look at the actual job.

That said, I like the idea! :thumb:
 
Do you know what type of consumer unit you have at the moment? 17th Edition, split RCD maybe? If you have RCD protection in the consumer unit and a spare way then it should be easy otherwise as it's a new circuit then the electrician will have to install an RCD.

I assume you'd want an IEC30609 (commando) socket? Might take some work convincing a sparky to install that in a domestic situation.

As Gethin points out, it is notifiable work. If the sparky is signed up to NICEC or any other scam provider than he can do that for you. It shouldn't cost too much.

How are you plannning on dealing with the supply in the garage? What is it going to be running? How are you going to distribute it to the things that need powering? You'll need to take into account voltage drop, Ze, RCD and MCB trip times.

Hello, thanks for the reply..... I'm not really that clued up on this type of thing but here is my consumer unit:



I want to simply be able to run an extension cable to my control panel:



And when the panel is not being used unplug and store the extension lead till next needed.

Should be ok with that CU.

In your control panel I would put an incoming fuse, or MCB and then fuse each individual circuit inside. There's a lot of current if something goes wrong.
 
Just done it myself.

You'll need a compatible MCB, some 10mm wire (I wouldn't use any smaller, no matter what anyone says) and a separate consumer unit.

I got a chint RCD consumer "garage" consumer unit. I got a 32A, 32A and 16A (though in retrospect a 20A would have been better instead of 16A)

Anyway, I also installed one of these: http://www.ebay.co.uk/itm/271313946449 - a "32 AMP 3 PIN 240 VOLT SWITCH SOCKET BLUE INDUSTRIAL GEWISS GW 66015 SURFACE"

It's handy as it gives a me a second switch to turn off the 32A socket. It's much safer, it stops the plug being pulled whilst the socket is on. Also, I've not yet wired a kill switch into my panel, so I currently use that (my PID is powered seperately)

I ran the cable myself. All the electrician had to do was connect it at the board and at the fuse board. He also fitted the volt switch. He's a friend, I got it all sorted for a couple of cups of tea.
