I just saw the posts and video about the effect of stray currents in gas pipes a bit scary to be honest but interesting nonetheless I was thinking that maybe a new rule should be that allgas pipes must be plastic coated where they enter the ground. Now I know if a gas pipe gets broken its likely to tear the plastic but its better than nothing.
I never thought scaffolding and handrails could carry diverted currents is there anywhere they can't get?
To the extreme, I'd even think that a worm orientated in the line between the transformer star point earth and consumer's cut out could have some current passing though it Kelly!
I bought my first "leakage clamp meter", must have been in 1993/4 and at some £400, it got used everywhere. The novelty has worn off since but still very useful to demonstrate to consumers having RCD tripping problems, by clamping around the meter tails (NOT the earthing conductor), the presence of "leakage".
It's also interesting, well to me anyway, to clamp the earthing conductor and measure with with main switch on and then off to see the presence of diverted neutral currents, entering/exiting the property. The most I've measured is 6 Amps.
