There are a few websites that are run by the regulating bodies that are full of incorrect information, the NICEIC website is one example.

The only body I actually believe or take any notice of is the IEE!

I guess you could always wire the sockets in the conservatory and then make the final connection using some 2.5mm flex, put a RCD plug on the end of it and plug it into a socket :wink: It doesn't come under part p then, I believe!

i told ask an electrcian about that once uhm and his reply was that if a socket is fixed to the building it comes under it even if it is on a plug

Look just do it, it will be fine as long as you do it all by the rules

I am not 100% sure about this, hopefully someone in the know will reply to this.

I was under the impression that anything that was plugged into a socket was not covered by the Part p regulations. There are some people out there now selling sockets that plug into other sockets!

if it is fixed to the fabric of the building then it is covered from what I was told, in the same way that an under oven is covered even though it plugs in

using a plug is imo dangerous and not an excuse to do a poor job

I'm still waiting on clarification from the sparks on here about this.

From what I am aware an oven is not covered by part p if it has a plug on the end, but it is covered if it is wired into an FCU.

Using a plug to supply sockets is not dangerous and can be safer than extending the ring main as those sockets will be protected by a 13 amp fuse rather than a 30 amp fuse or 32amp circuit breaker. Use a plug RCD and it is safer still!

I have a feeling that your sparks may be telling porkies in order to make a few more quid, but lets wait and see what the others think :wink:

The problem is that the rules are often open to interpretation.

By reading point (ii) above it would seem in my opinion that you are allowed to add to your existing ring main without notification.
The April 2006 version of part P includes guidance notes which make it clear that extending an existing ring does not have to be notified, provided the extension is not in a kitchen or special location or associated with a special installation.

The need for RCD protection is determined by BS7671, not part P and is a matter open to interpretation.

What If the existing ring services the kitchen, can i still extend It into a conservatory or Is It notifieable because It shares the ring with the Kitchen? i hope this makes sense. :?

As long as you are not taking the feed from a socket in the kitchen then it should not be notifiable.

Don't think so.

I'm not well up on part p or the rules regarding electrical installations.

Plug something into the socket and if it doesn't work you have done it wrong, you don't need a sparks to tell you that lol

I use one of these-

Yep I got one of those!

I could do the whole install to BS7671 (ish) but not testing etc!


Any one any idea how to enable (if possible) an rcd protection on the extended circuit or must it be done on the whole ring supplying the extended circuit? Questions questionsand more questions! :oops:
if It's notifiable ..........Forget it!! :lol:

You might be able to take a spur from the existing ring main and then use a rcd fcu-

You might struggle getting the wires in the back, unless you use a reallydeep backbox.

plug the socket tester into the ring you wish to extend before starting any work to see if you have a fault already. If not then add the extra sockets


If you arent going to get an electrician do the work, then there is little point getting them to test the work. And therefore if you are going to do it yourselv there is little point putting an RCD on the extension of the ring, in fact it is probably impossible with a ring.

So just get on with it, or get a spark to do the full job

Thats the whole point of this discussion, do I DIY or get a Sparky? If I DIY Is It legal? If not then I'll get a sparks to do It! But thats what forums are for....... to see wots wot!! :wink:

I guessed it would be difficult to RCD protect the ring...but hey thought I would ask!

BTW I want to add lighting as well so It's a job i can save a few quid on if I can without cutting any corners on safety and keeping the lawyers happy.........As if :lol:
