Running main bonding conductor
I have to run new 10mm^2 bonding from CU to new stoptap location. Does
it have to run in safe zones like live wiring ? Thanks, Simon. |

Nice one:-) I have always installed it in the safe zones or followed a, c or d here http://wiki.diyfaq.org.uk/index.php?...and_Protection But it need not have 30mA RCD protection:-) -- Cheers Adam |

You could drill through the main bonding conductor and never know about it. Simon. |

I like having supply tails visible for ease of visible inspection, and to get that small addition 5%(?) of current-carrying capacity. Useful when most of my installations have to be designed from scratch rather than book-standard circuits. JGH |

If your water stop tap is in the kitchen, with gas an electricity in the garage, for instance, there may well be a considerable run of cable.

Running main bonding conductor
I am sure my customers would be delighted to see me clip a 10mm green/yellow down the wall when doing a rewi-) Who says you need to use green/yellow cable? And might that also just possibly be the answer to the original question? Reg. 522.6.6 (about the zones) only applies to "A cable concealed in a wall ...." IIRC ('cos I'm too mean an amateur to have bought the regs.) the regulations for the main equipotential bonding (544.1) specify a conductor but don't require it to be a "cable". As I can't find a definition of cable I assume it takes its ordinary meaning, so if you use something that's clearly not cable as the conductor - eg copper pipe or lightning conductor strip? - for the main equipotential bonding then ...........? Of course it might be a bit of a challenge to fit copper pipe into the MET and clamp it to the water pipe though I'm sure I'd find someone here to tell me what to do ) That said, I suspect I'd fail the unwritten "no bloody smart-arse shed-lawyer solutions" regulation -- Robin PM may be sent to rbw0{at}hotmail{dot}com |
