But i guess i can spur of the socket to a 16amp RCD with a 16amp 3 pin plug in the workshop.

An RCD will not provide overcurrent protection, you need an RCCB or RCBO.

Ok then, so i have a 30amp fuse in the mains consumer feeding 2.5 cable to the non switched cooker socket ( only supplies the oven not hob ), and then if i use 2.5 cable from the cooker socket, then whats the best thing in line before the 3 pin 16amp wall socket.

I take it then this is no good, or can these be fitted with a RCCD or RCBO?

the cooker supply should be wired in 6.0mm cable with a 30 amp fuse feeding it or a minature circuit breaker . if the cooker controll unit is fitted with a 13 amp socket and your oven is only 13 amp plug it in there .then run a 6mm cable from the controll unit out to the garage consumer unit that allready has an rcd mainswitch fitted and also the 16 amp minature circuit breaker . then off in 2.5 to your welder socket and the jobs done . if its a double oven and both can be used at once and its fixed wired u cant take of the cooker circuit

What do you mean by `fix wired`

It is a double oven 1 small and one large.

cheers wolly[/QUOTE]fixed wiring means its hard wired. in to the back of cooker controll . portable means plugged in and can be un plugged. so can u use the both ovens at once if so its probably hard wired . if theres a selector switch so only one can be used at any 1 time its probably on a 13 amp plug

Thanks for the help mate, yes it is hard wired then, so to make this better i will just start a new feed straight from a fuse already in the consumer unit, as there is no spare, to the work shop, i will need a 12-15m cable run ( not measured it eyt ) but not end of the world, but it will need to go along the house gable above the con`y, i will fit it in conduit also, will 2.5 cable do the job then mate. If it can could i run the rest of my tools from it with the garage consumer, at the minute i am on an extension from the rings mains in the house.

cheers

I had plenty pf spare spots in my consumer unit but to keep thing safe and seperate I got another small consumer unit added direct to the mains feed, run appropriately heavy steel metal armoured cable (10mm in my case) to the workshop and a donsumer unit with mcbs for lights and sockets.

It cost a bit but it means nothing I do in there should effect the house or it's electrics and I should be set to run power to as many things as I need. In fact the way it was done was possibly overkill but you'll only ever do it once so best to think ahead.

 

[bigtip]

proper job!

 

[W.olly]

Sounds a good job but a bit OTT for what i need as all i will ever be running is a welder no bigger than 250, and thats if ever increase from the 200 i am getting.

Will 2.5 do though from a used 30amp ring fuse to the workshop consumer?

no it wont it needs to be 4.0mm minimum for 30 amps fed of its own fuse not in with any other circuit . use 6.omm as theres hardly any diffrence in price

 

[bigtip]

it's worth doing it to a higher spec than you think you need now, you might want to run a compressor one day or even a plasma cutter

but i'm confused by your last post now.. i thought you said you had supplied the workshop c.u. in 10mm?

 

[W.olly]

You mite be getting me mixed up with Dev in this post

I had plenty pf spare spots in my consumer unit but to keep thing safe and seperate I got another small consumer unit added direct to the mains feed, run appropriately heavy steel metal armoured cable (10mm in my case) to the workshop and a donsumer unit with mcbs for lights and sockets.

I have been runnin g all my work shop from a the ring circuit off the house, infact have done for over 10 years, i have run a 3hp compressor, 40amp plasma, and a Clark 151TE mig, plus the bench drill etc etc, not all at once though LOL. All the work shop besides lighting was run by 2.5, never had any problem at all, i went this way as a sparky i knew suggested to do it that as i wouldnt of needed to go form the house C U.

I only want to make sure i wire the new 200 welder in correct as it is bigger, i believe it will run on a13amp plug but not at full power.

The sales man said to fit a 16amp plug i can spur off a standard 13amp socket to fit a 16amp MCB then a the blue 3 pin to welder, but know from all your advice its not possible.

I will see the cost to get a new consumer fitted in the house with more out puts and get a 6.0 cable then to make sure.

Thanks for the help guys, i mite infact go bigger as i am getting the feeling i mite be getting some bigger jobs on.



Edit to say i have just realised, well the wifey has, we have a spare C U outlet from the shower we once had, so i dont need a new C U, just a load of 6.0 cable and a garage C U etc and we are off, at last

 

[bigtip]

you are correct, i was confusing you with Dev...

old shower slot sounds perfect. i've got my workshop supplied with 6mm also. originally just had a 2.5mm supply but it was a longish run of cable and then i got a plasma. the compressor struggled to start whilst cutting due to voltage drop till i uprated the supply. still struggles a bit mind you, but doesn't usually trip the thermal cut-out anymore.
