Using an earth rod to bond gas and water??

[Lectrician]

and its a terraced house!!!
cant go round!

There is always a way.

If it wasnt 'just a bonding cable' but was a cable for your Sky TV, I am sure you would then soon find away.

its a listed building with concrete floors and ceilings! All newly decorated with the CU at one end of building and gas and water at other end!!

There is a special clause in BS7671: 2008 that says (from memory)

544.1.3

"Newly decorated properties and those with solid flooring and certain listed properties are exempt from certain regulations, including those of main protective bonding conductors. See Appendix 16 for alternative acceptable practices to be employed in these circumstances."

I think you need to stop what you are doing and get your books back out.

First of all, have a read of chapter 13 in BS7671, and see if you can work out where you're going wrong.

My advice is to take what has been said with a pinch of salt, but also reflect on the comments and consider doing a refresher course on BS7671(the regulations that qualified sparks work to). Being qualified is more than just getting a certificate - you need to keep upto date with the regulations and the requirements.

Just out of interest, what make consumer unit where you going to fit, and what model? What circuits where you going to RCD protect (if any), and do you know what earthing system is present at the site?

This forum is for advice

Ban, let me beat you to it:

Yes. It's for advice. We've given you the advice. It is that you should in no circumstances connect PEB's to a rod. EVER!

But you keep posting "excuses" why you can't possibly run the PEB's to the MET, and it looks like you're going to ignore our advice.

I appreciate your plea that you are not a dom. spark.

But, as others have said, this point about PEB's is common to wiring systems in all of the disciplines, whether domestic, commercial or industrial and the principle of equipotential bonding is very basic UPK.

It is a TN-C-S system.

I am proposing to install an 8way 30mA dual RCD Wylex board.

I HAVE TO SAY THAT IF YOU ARE NOT ALREADY AWARE, THIS IS A WIND-UP. LOOK CAREFULLY AT YOUR COPY OF BS7671:2008. THERE IS NO REG: 544.1.3 AND NO APPENDIX 16.

Ah, the one system that relies on proper bonding more than any other

 

[securespark]

It is a TN-C-S system.

In which case it is even more important to do the PE bonding correctly.

I do appreciate everyones advice! But my backround is being given drawings with circuit references and installing containment to accomodate! I am perfectly capable of connecting circuits up in a board and testing. But not fully clued up with the main earthing!

I did twig!
