What's the difference resistance wise over a bit of 6mm or 10mm Earth wire over the average distance of 10-15m in a house for the bond to the water or gas?Every time I change a cu I update it, maybe it's just me, but if I went round changing cu's and left a 6mm green conductor in on the bonding every time id feel I'm doing something wrong.
an electrician that does not know that a 6mm green to a water pipe is a bond is not much of a spark in my eyes
why? its safe for continude service so no issue.I know it's the sodding bonding, I'm not suggesting I don't, I just think it should be updated.
the regs are not retrospective so no.If it's TNCS it would need to be 10mm
In a new installation yes you are correct.If it's TNCS it would need to be 10mm
Personally I wouldn't leave a solid green conductor in place on the bonding, ok I know it may be in the back boxes etc on the CPC and the like. I don't know, but I wouldn't be too happy leaving it.
