Flying leads and the regulations.

No you converted me, as we speak I'm drawing up a plan to fit all my metal work with BS 951 clamps and earth everything, I think your right this is the way forward

Don't forget your toothbrush holder. It could be wet.

Thanks geoff ................. would you use 4mm for that or do you think I could get away with perhaps 2,5??

 

[Geoffsd]

Earthing limits duration of fault

Bonding limits the magnitude.

2.5 if mechanically protected. run some galv. conduit up the bathroom wall.

 

[malcolmsanford]

Earthing limits duration of touch voltages;

bonding limits the value of touch voltages

I would go more with this to be honest

Sorry, but 2.5mm² will not be acceptable as a bonding conductor.
6mm² is the minimum, and where PME conditions apply, 10mm² is the minimum.
However, I would also suggest you determine the requirements of your supplier, as they may require 16mm².

Water? tick
Gas? tick
Structural steelwork? tick
Toothbrush holder? tick

This actually illustrates the problem very clearly There should be ONE set of rules which everyone works to. It used to be the IEE regs which had only one "current" edition which encompassed everything electrical, we now have a hopeless mish mash of guidlines ammendments and explanatary notes issued by organisationd which are actually in financial competition with one another, oh boy am I glad to be out of it after 40 years!!

There is one set of rules bs7671 2008 amendment 1!

As for there is no difference for earthing and bonding.....
Your on your own there.

Some people simply just won't listen

Cheers and gone

As said by Rich.250, there is only one "current edition" and each new edition is issued because of improvements for safety. Things change, even the IEE. Isn't it the IEEE now?

No, the IEEE as far as I'm aware has been in existance since 1884, originaly founded in New York.
The British IEE, is now known as the IET.
