Okay so, I have a shed down the end of my garden where I like to weld and do stupid stuff. Anyway I have an arc welder which at maximum power gives me 160A @ 20V which is 3200W. When my parents built the shed they didn't take into account that there son was going to be a raging metal melting maniac and hence there is just 2 G-pin 13A @ 230V AC sockets in the entire shed, very inconsiderate I know. This of course allows for a maximum of 2990W which just isn't good enough if I want to weld thick steel without the fuse going every 2 seconds.

Luckily the electrician clearly saw my future struggles and popped in a 25A breaker for the shed on the mains board back up at the house when it was built. But here's where things get a little iffy: The cable for the shed comes in though a big dirty black wire from the house underground and goes straight into the G-pin sockets and then a smaller grey wire goes from the sockets to the strip light up above. (I've attached a highly detailed diagram below) I assumed that the strip light was just in parallel with the power coming into the sockets and turning off the power for the shed at the breaker would therefore turn off the sockets and the lights. But alas it only turned off the sockets and the lights are still fully functional. I don't know what witchcraftery this is but I don't really want to open up the socket and have a peak if there's live electricity going through her. My plan was to just attach a big 16Amp connector to the big dirty cable but it seems a bit tricky as I've no idea whats going on inside the socket.

Thanks in advance,

I am absoulutely welding it myself, theres no fun in making a hydrogen chamber if theres no chance at all of it killing you, I also don't always go with the cheapest option i've had about 7 different electricians so clearly the paddy ones must just be rubbish. I've got my answer anyway so thanks gentlemen i'll be on my way

peace ou
 
The normal method would be to use an FCU
There won't be relay in that box it'll just be junction box.

I wonder if that been installed using a 3 core SWA sharing a neutral between two circuits. It wouldn't surprise me. Either that or the original installer have some free swa.

do the reg even let you do that? I

It's a rough as dog arse. The OP going to end up killing someone or himself.

Quite... Brayjing :D

spoon the op not listening, this post needs closing.

I was just taking the micky out of the location he put mate.

Are you sure there’s a relay in that box? It looks more like a joint box than a relay enclosure.

I'm not worried about you, you've already demonstrated you're capable of disregarding your own safety by insisting on attempting this work yourself.

I'm concerned any poor souls who happen to be in the vacinity when you do actually create a bomb and cause damage or kill someone by electrocution because you didn't get the work done professionally.
 
seems like he cheaped out big time, hes gone and cut wires at the very bottom and left them exposed and didnt want to use an extra connector for the earth

Actually if it was protected by appropriate devices in the consumer unit, it's probably not that bad. Nowhere near as bad as the light being connected directly to a 25A breaker.

See that photo up there? That's what "professional" is around here. I can do better myself
