Title: conservatory electrics
Post by: gtlee on March 13, 2011, 11:02:59 am
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. :happy2:

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

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

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???  :confused:

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?

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! :mad: :mad:

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???  :rolleye:

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.

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

Running cables horizontally behind skirting boards is a NO NO.

This is not a defined 'safe zone'.  :fighting:

Did he tie his horse up outside while he did the work?  :grin:

Unless I have read this wrong and the cables go down from the socket behind the skirting board into the floor void? or down into conduit embedded in a solid floor?

In these cases thats fine as the cables are run in a 'safe zone' but if he has run the cables HORIZONTALLY behind the skirting then :surprised:

Its a bit far from me and I don't know anyone up that way.

Just make sure you use somone registered with ELECSA, NAPIT or the NICEIC  :happy2:

if the cable is buried it must be mechanically protected or the circuit protected by an RCD.  Me personally i would do both.

get a proper Spark in as well, not some kitchen fitter/part time sparky.  All Part P does is show that someone knows how to read the contents page of the Part P guides and building regs it doesnt make them any better, and remember most of them were bodgers before they did the Part P course

Thanks for info. Ill phone the electrician and find out what he did exactly.I do remember him saying that he would have to cut a channel out of the skirting to keep it flush to the wall.   Didnt see a horse but he could have tied it up around the corner

I suppose making them aware of the regs, guidance notes and standards etc can only be a good thing.  Im not a fan of it tbh, and think its more of a money making clause.  

Im part P as well, although i dont really require it for my job,  i rarely touch domestic, They offered me the course, so i accepted as i got it paid for.

Being a member of a competent persons scheme can only be a good thing IMO albeit a money maker for the companies running the schemes.

At least you have to be assessed every year and a number of previous jobs inspected.

The bad aspect to all this is that it will never stop the cowboys as being a member of one of these schemes isn't cheap which means the cowboys out there will always cash in on the cheap cash in hand bodge job  :fighting:

Although I always look at it that I'll usually get called out at some point to rectify their dodgy work anyway.
