Any sparkies on the forum? Advice needed

[Error404]

I'm planning on doing some work to the garage - adding a proper supply for power and lighting.

Currently there is a spur from my kitchen (downstairs ring) into the garage feeding a double socket, 2 x single tube lights and an outside security light.

I want to add a proper 30amp supply for my MIG so I can use that properly without fear of torching the house
Also I want to add a mini ring in there for 6 x double sockets, and a lighting circuit for say 4 x strip lights in the garage, and another circuit some lights in the garden, security light etc.

I guessed it would be best to take a feed from the main house consumer unit into a mini consumer unit in the garage? I could run an armoured cable from the main unit in the house, outside under the patio to the garage.

I'm just no techie enough to know what kind of rating ampages, cable sizes, RCDs etc I need - can anyone in the know give me some guidance on stuff to think about?
A kit list would be dead handy


Cheers

I know "Topsparky" is an electrician...

Drop him a PM... Might be able to help... If you had to get some in to do it these days they have to be "Part P" qualified and needless to say this really does bump up the price...

If they use the new Brown, Blue & green/yellow wiring it has to have a certificate or you could have problem when or if you want to sell your house...

I found this out when we had an extension built a few years ago...

This is just "As Far As I Know" & am probably wrong!!

Any wiring work of that extent "should" be signed off by a NICEIC or similar
certified electrician. There is nothing to stop a competent person doing the install
as long as the final connections and testing is done by the electrician

If I were you I would put a consumer unit in the Garage fed by something like a 10mm cable from a 45A RCBO in the main Board

Don't know what type of MIG you have, The 1 I have uses a 16A Blue plug so only
requires 1 x 2.5 cable and a 16A type C or D breaker

Sockets in a ring 30A, Lights 6A, External socket 16A which is enough for lawmower etc

Testing 2-300 or mates rates depending, Only need cert for selling house these days

Hope that helps

Thanks chaps - yes I know its notifiable work under building regs but I can't be *****ed with the hassle / expense just to get a sheet of paper.
Was planning on doing the main install myself then get a guy I know who works for National Grid to come over and check / test it before going live. No way I'm paying some **** scratching contractor to come in and tick some boxes as the house won't be for sale any time soon and i can get all the components at cost from a friendly wholesaler.

Good info thanks Paul. MIG is a 160amp jobbie, suopposed to have a 30amp supply although I'm conscious it'll never draw that much with what i use it for... just thought i'd go belt and braces since I need to put a proper supply in for the lights and sockets.

"IF" you can get hold of any Black/Red Wire ring main wire you will be fine as it's only the new stuff that came in after the regs that would flag up on an inspection...

I have a few rolls stuffed away...

Again thats as far as I know... (A customer told me this as he bought as much wire as he could off ebay so he could still "BEND" the rules). Can't for the life of me remember his name...
