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

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.

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.

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

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

What is the alternative ???

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

So what is a distribution board? How far down the line do you want to go.
Every board shown here is a "distribution board". They get smaller as you go deeper in to the system.
