conservatory electrics

[gtlee]

Hi need to pick your brains on the the subject as titled above,

I'm having a conservatory built and need to know the best and right way to wire up two lights and maybe 4 double sockets, btw its going to be 600mm brick face inside and out dwarf wall all round but one side a 3/4 the other side.

I've read you can't put cable in the cavity wall, don't want truncking exposed on the wall face either and its a part P job not diy?

Any info would be great.

We had ours done a couple of years ago & i'm shure the cabels etc were just ran through trunking in the cavity wall. Get them to add a TV point as well.

So by either truncking or conduit the cable will be fine then,any sparkys here that can verify advise.

Get them to put some electric windows in the roof too! ;)

Yes it will need to comply with Part P but if its not a new circuit then it will be minor works ( spuring off/extending ring circuit from adjoining room).

You also need to upgrade your main earthing conductor and or protective device if it hasn't already been done.

Standard T+E cable in plastic conduit or SWA cable is fine but I like to use Pirelli FP cable as its much easier to terminate.

Are you intending to do this yourself????

We dont have a ceiling light and use lamps.2 double sockets fitted above skirting so you have somewhere to hide the cables

Are you saying the cables run behind the skirting???

JPC, having those wide opening bi-fold doors aprox 3.6m opening so that would vent some heat out, had a look at those too.

apollo13, Yes it will be an extension circuit from the living room, so placing cable in conduit/ SWA cable will suffice then and still notifable?

.............just had a look in ours & ''yes'' thats what they did with ours.

If its an extension from an existing circuit in the house then it doesnt need to be notified BUT that is only if the main earthing is up to currrent regs and you have RCD protection on the circuit your are extending.

Also most people use the building of a conservatory to add an outside socket/lighting which then makes the job notifiable aswell.

The groundworks and walls are getting built by my builder but the conservatory I'm putting up with a mate .

Don't get me wrong but this Part P biz is such a pain in the A, had a read of it earlier just gets confusing more you read it and anyway why do they allow the DIY stores to sell all electrical items when you can't really DIY it!

Sorry for the rant.....rant over for now!

I'd get help from a local sparks mate.

Even if you extend an existing circuit how do you know the circuit your extending is safe to extend???  

To be honest most people sod the regs and do it themselves regardless but being a sparks myself I need to help give you the right info.

Safety is the most important thing here..

The DIY stores sell stuff because you are allowed to replace like for like in SOME certain locations such as bedrooms, lounge ect.

But I don't agree with them selling C.U's (fuseboxes) and meter tails ect.

apollo13;  Cheers for the advise I'm gonna get a sparky to have alook at and connect up and do it legit.

No worries 

Where are you on our lovely island?

Yes hidden out of sight.  The electrician cut a groove the length of the skirting so it fits flush to the wall
