Hey chaps.

I found a link to a PDF of the issue of Wiring Matters in question.

Click on the link, and then "start download" then "open" to view.

Cheers.

Additions and alterations.pdf

Interesting read but i can't help but thinking that if it is correct that the law is an --- to quote a well known phrase. It sounds like you can't improve a potentially dangerous thing unless you correct the whole thing. Which in many cases is going to mean a new consumer unit. The customer wants to make an improvement , say an extra socket to prevent over loading and trailing leads but can't afford a new consumer unit. This means that the qualified and bona fide electrician has to walk away from the job which could have resulted in the situation becoming safer, having first wasted time and money to go out and inspect and quote. Customer wants job done so turns to unqualified cowboy . How can this be considered to be sensible :mad:. Things like this make my blood boil. Somebody please tell me i am interpreting this wrongly.:mad::mad::mad:
 
Indeed.

What we are unsure of is that if any circuit that is added to or altered etc must it be brought up to date with for eg and RCD protecting that circuit or just from the addition onwards?

This could be achieved by either fitting a new 17th CU or breaking out the tail from the existing CU and installing them in a separate enclosure with RCD protection.

What Andy is saying is that he has been informed that its only that PART of the circuit that must be brought up to date, and not the whole circuit.

Must admit, whenever i have had to do alterations and additions, i have always put an RCD upfront.

But thats me and others may do different.
 
You'r interpreting this wrongly.
do you mean it or are you just trying to cheer me?

In the example in the article they say that you can't put an extra socket in the ring if it is not already RCD protected, without then going onto protect the whole circuit with an RCD. If it is an old CU that would then involve either changing it or putting a stand alone RCD on to just that circuit - neither of which would be cheap and could put the customer off.
If it is not saying that what is it saying?

Surely an RCD protected spur would be a cheaper and more sensible option if the customer is short of cash

(EDIT was writing this while Jason made his post)

The article that lenny linked to says its the whole of the installation/circuit that must be brought up to date and that if not, you should not do the job

Thats what i was saying i do.:D

But Andy has spoken to the NIC and they told him its only the part thats been worked on.

Not sure how you are supposed to do this on a RFC or if you are extending a radial and the new cable is less than 50mm etc etc.

If you are installing a socket or the new cable is less than 50mm etc etc, then you have to fit an rcd as per the regs.
The op was about a light fitted in the loft.
My point was that the way I read it you do not have to fit an rcd because other parts of the existing circuit is in a wall less than 50mm deep with no earth protection.

It just seems mad that you have to turn down a job that could lead to an improvement in safety just because it does not correct everything. The customer then turns to someone who is not qualified.:mad:

Is there not a body or union or something that can look into this type of scenario for the electrician. It just seems to be encouraging a black market in illicit/cowboy electrical work (if you know what i mean)

Your point on page 1 of this thread is sensble IMO. The article that lenny linked to says that is not the case though the whole of the circuit would have to be protected and that pointing this out to the customer on a certificate would not be a defence. In my own mind i am not 100% convinced of the author's arguments as BS 7671:2008 are guidelines and not statutory, so to my mind you could argue that your work could be improving safety even though it did not meet those guidelines - even if you did have to do it in a court of law :mad:

Absolutely agree, however, how do we go about this if we are extending or altering a few sockets on an existing RFC or extending a cooker radial circuit to the other side of the room that has no RCD protection?


Pushrod, there are many, many things in this industry that are totally incomprehensible, but most of the time, you just kinda accept it and do the best you can.

There will ALWAYS be unqualified or unregistered tradesmen in ANY industry doing what they please.

You have to fit an rcd as per my previous post.
