Water and gas Bonding on three-Phase

[rosewood]

Hi All, Doing a big remedial job on a factory and changing main incoming tails to 240mm. On inspection found there was no bonding to water and gas. Surely that doesnt mean i need 60mm bonds? also does the clamps HAVE to be bonded next to the incoming water and gas meters or is there a 'get out clause' where you dont have to do it?? If so this could end up being a 60metre run :saddam:

Thanks in advance

Where do you get the figure of 0.05 Ώ from for an industrial situation?
Start using the structural steel and the figures will drop far lower. This is where a Ductor comes in to it’s own. Readings down to 0.0005 Ώ will be found.
