Main Bonding Plastic Water Pipe

[vespa]

Hi I have noticed that the water pipe in my own house has mains bonding to the CCU. However the incoming pipe is actually plastic that has been painted white. I know the on-site regs say bonding in this circumstance is not necessary. It is however providing an earth passage..albeit into the building. As I intend to replace the CCU shortly would any kind person please advise if is better to remove completely or bonding or leave it where it is the continuity reads 0.07 ohms. Many Thanks

yeah...you`l find `pink handcuffs` over on the scaffolders forum....

I have been told to use the term 'consumer unit' or CCU in my college work, as using incorrect terminology, such as 'fuseboard' or 'Megger' when referring to an insulation resistance tester will get you marked down. I was under the impression that a distribution board distributes power out to further boards, and not to final circuits.

On Thursday at college we were suddenly told (after 4 years) that we can't call them MCB's and they should be called 'circuit breakers' instead!

Obviously I still use the terms 'fuseboard', 'light fitting', and 'lightbulb' when talking to customers so they know what I am talking about. If you tell a customer his Zs at the luminaire with the CFL out doesn't allow sufficient PEFC and needs a supplementary CPC he won't have a clue what you mean!

Surely the terms CU? CCU is a cooker control unit

 

[Stroppy]

No its not, its a Consumer's Control Unit. It may be cooker as well.

a persistant problem on the 2391....
i have had a look at previous chief examiners reports and time and time again comes back the `wrong use of terminology`....all the things you mention here such as insulation resistance testers being refered to as `meggers`...and low resistance ohmmeters being refered to as `continuity testers`...all a load of cobblers....
further more there seemed to be a distinct lack of foundation knowledge as regards to earthing arrangemets and the roles earthing and bonding play....to the point where main bonding conductors were refered to as `earth bonding`.....
another one was the lack of understanding about where to apply correction factors to Zs....measured or tabulated...
the list goes on...

That's stupid!!!

Which bit of it, there's so much to choose from!

Sorry lol, I meant the bit about calling MCB's circuit breakers when they both mean the same thing! It would be like saying FCU is incorrect terminology and you have to say fused connection unit even though they both mean the same thing.

 

[oldtimer]

A bit like calling ISI&TEE PAT lol

Yes it is silly isn't it. It makes me wonder if there is any difference between an MCB (miniature circuit breaker) and an MCCB (moulded case c-b), or an RCD and an RCCB.

According to this site: What is the difference between MCB, MCCB, ELCB, and RCCB | EEP there is a difference between an MCB and MCCB.

Oh yes, it annoys me when people refer to an FCU as a spur.

 

[oldtimer]

Just to add at the time PAT was a great description but that came back to bite everybody in the bum when people say you are talking crap about testing fixed appliances because why else would you call it Portable Appliance Testing so your not tricking me as PAT means portable equipment only

 

[Geoffsd]

The biggest mystery to me is why RFC stands for Ring Final Circuit.

What is the alternative ???

 

[vespa]

Wow!! Did i pick the scab off that one.

Found the answer chaps P38 of the electricians guide to the building regs. States it should still be bonded but on the customer side.

That should reduce the e mail traffic now . Thanks for your inputs.

Cheers Vespa

Hi Vespa

post #3 had the answer in.
