do you have an electric cooker installed or has the circuit been diverted?
is there a consumer unit in garage to fuse down for lights etc.?
is garage backed onto kitchen cooker wall and taken from cooker unit for convenience ?
have a look' give us a clue, any work involving a new supply circuit, or any work in garage or kitchen covered by part p so probably best to get a sparks to look & quote to remedy if not right

Hi sparx

Yes the Garage backs onto the kitchen wall where there Electric cooker is.I dont have a consumer unit in the garage just a wire coming through the wall where the cooker is it then goes into various junction boxes to supply light and sockets.I do beleive the last ownser of my house did it for convenience.

I would like to put a garage consumer box in there & will consult qualified sparky in later.

Is it safe for now, as its running off a 30amp fuse(Cooker) I dont run much in the garage(Just a fridge & mower)

so.. you have a lighting circuit wired presumably in 1.5 mm cable capable of carrying 11amps 'protected' by a 30 amp fuse!!!!!!!!!!!!
If a fault occured on circuit the wiring would melt catch fire etc and the fuse would not blow......
DO NOT consider using mower without at least using a Power breaker plug a sa very temp. measure .
You are breaking the law if you do any changes in the garage your self..GET A REGISTERED PartP leckie in v.soon please, you are in DANGER.
your installation, like so many DIY wiring lash-ups has killed far too many people already.
Please be careful, I have nothing to gain from this, but the more I read on here the more worried I get, folks just don't seem to realise how lethal 230 V is..........

Hi sparx

Yes as I thought. now i've inherited this mess :x from the last owners. I will get a leckie in to sort out!!!

I'm planning and extension soon so will get this sorted then.

I have a breaker pluged in when using anything as i thought this was not right.

So as it stands you would not recommend using anything out there.

Cheers.

Hello Sparks

I got a approved electrian in, he has advised me that he can come back and either do one of two things.

1.Strip everthing back and feed new wire from main cunsumer unit .

2Put Garage cunsumer unit on from 30amp feed with 16amp for sockets and 6 for lights and make new ring main.

He said item 2 would be cheaper.

So seems to be ok

Also im going to college to sit my part p so i can do it all myself later.

Hi
The wire comes in to the garage from the cooker point which is fed by
a 30 amp fuse and then goes straight to a junction box (plugs) and lights
So all you need to do is...
Buy a fuse box with two fuses in it, one 6amp and one 16amp
Take the wire coming from the cooker out of the junction box and place it in the new fuse box and fasten to wall (making sure its not live)
Then wire a 2.5mm wire from the 16amp fuse to the junction box (plugs)
and wire another wire 1.0mm from the 6amp fuse to the junktion box (lights)
This will make it safe but please check with an electrician that this is a suitable solution under Part P of the building regulations.

Hi Steph

Thanks for you comments, I checked on what you suggested and it is ok to do that.

I will buy suitable garage unit tomorrow and fit, I have a part P mate next door who will check work.

Cheers

just one point, it isn't necessary to have work done by a qualified electrician to conform to part P, it just needs to comply.

whilst an attached garage may not be covered by partp, any work that is part p area, say a detached garage can be done by yourself or an unregistered person. BEFORE starting such work you must notify local building control dept. & pay a fee for them to visit (or such agent as they may appoint) twice during work. First when wiring, boxes etc installed to check cable routes etc, second at completion of work to check connections etc. however a registered electrician does not have to do this & can 'self certify' his work & register it on-line at the end for a very small fee.
