Another garage wiring question

[madkayaker]

the only way to meet "competent" for part P is to be registered with a part P body its a pain in the **** but that the world we live in

Fraid so

The only way for completing work to a competent standard as a business is to be registered...

You are still free to undertake work in your own home yourself as long as you work to the required specs...

try wiring your own extension and then get building controll to pass the whole job off and they wont

 

[Omniata]

As long as you inform them of your intentions and don't make the final connection your free to do it...
They can't pass it as said, it's up to them to pay a sparky to do so out of their own pocket...

If you've done everything that's required there's nothing to be worried about...

They can't, legally, fail a system without having proof from a "competent inspector", again at their expense, that the installation isn't up to standard......


Edit: I'll note that whilst other structural work being undertaken at my house was being inspected I offered to the building inspector to see some of the basic rewiring I had undertaken some time ago...
He was satisfied with the work, at which point I showed him copies of the websites discussed earlier in the thread...

He said he'd be happy to allow me to continue if any further work by myself was carried out to the same standard and I kept them informed. Whereby he admitted that the work met "competent" requirements and therefore by definition I was competent...
However, he did inform me that whilst I could carry out work in my own home I would not be free to do so in somebody else's without being registered...

I do get on quite well with building control round here, they don't like costing themselves more than necessary...

Just my two penneth...

you may do a certain (very) limited amount of work, but not in a "special location"... ie anywhere where there is water or outside

outside power .kitchens . and bathrooms other than that u can conect to existing circuits but if u arent getting anything done with building controll sticking there nose in just do it yourself as long as the jobs up 2 the mark . even if u sell your house they dont generaly want to see any paperwork on the wiring as long as it looks new ish and now hips has gone the journey its a free hand

 

[mike os]

also worth pointing out you are criminally responsible if the work is carried out incorrectly or not compliant with BS 7671

Lot's of good points being raised here and clearly I have a lot to learn!

So with regards to my installation,I'm planning on doing the following:

• Taking power off my current CU from a 30A fuse
• somehow connecting 6 mm 3-core SWA into that 30A fuse
• connecting into a little IP65 CU for the garage (35m away)

Inside the garage CU there will be:

• 16A MCB type B?
• an RCBO? (Do I need this? what is one?)

So in the garage that will get me a good reliable source of 16A power with not too much of a voltage drop. Then I should be free to connect my 15A socket into the garage CU and get welding (just a concern about the mismatch in rating between the 15A socket and the 16A fuse? Should I be using a 32A socket?)

Thanks again

the sockets and plugs are 16 amp so no probs. an rccbo is a residual current circuit device with built in mcb in laymans terms an earth leakage tripswitch with built in fuse. either 6 amp 16 amp 20 amp 30 amp ect or do u mean an rccd main switch in cu

Not really sure what I mean to be honest!

I've just heard the term mentioned on here and wondered if it was important. I don't think my ancient CU will take one though!

Cheers

[mike os]

it wont

I would put a sub board in the house with an RCD, 6mm 3c SWA & new cons unit in the garage fitted with RCBO's to each circuit and disconnect the current supply to the garage.

RCD/ELCB disconnects automatically in the event of a fault
MCB disconnects in case of an overload
RCBO combines both the above in a single unit.

MAke sure teh earthing is done right.

 

[brightspark]

its pointless putting rcbo/s in the garage if u have the rcd back in the house. just get a mainswitch consumer unit for garage with mcb /s

Morning all,

So I've been looking at what I need to buy and I think I've found the components I need to do the job.

Garage Consumer Unit:
http://www.screwfix.com/prods/33248/Electrical-Supplies/Consumer-Units/MK-Consumer-Units/MK-IP65-Garage-Unit

The 32A MCB for the existing fuse box:
http://www.tlc-direct.co.uk/Products/WYB32.html

So once I've got my SWA and a few glands and metal boxes I think I can get on with getting it installed.

I think I read somewhere that you can terminate the SWA into a metal box but bring the cores through the box and into your CU. Does this sound feasible?

Cheers

use either a 22mm conduit through metal box or a square 3x3 metal box put the gland on and take the 3 cores strait through into plastic consumer unit. metal box wants an earth link putting in and keep box close up 2 the fuseboard with none of the inner cores showing
