110 V Across Earth Terminal's...any Ideas

[apprentice87]

Screwdriver earth rod... Yes, i have often thought of that, but not mentioned it as i thought people would laugh!! A neon [steps favorite tool!] would be fairly good, [in the case of 100v upwards] but i suppose only as good as the "earth" you are standing on, which might be well different to "true" earth, [as various racehorses will testify]

john....

Binky,

I carry an analogue Avo in the van.

It still has a place in my fault finding armoury.

I will confess to not using a screwdriver if I want a real, true earth potential, I tend to use one of the stakes from my earth rod testing kit in truth, but the same theory holds true.

Ahh,,, but when you have TT installation in a mid terraced house with the front door opening onto the street and a concrete back yard you haven't anywhere to put it

Why do you think lamp posts are always outside those properties!

Sharp,

I would not rely on a lamp post.

I said something of the like to a guy I know very well who works on street lighting for the local council the other day when he was at mine having a cuppa.

He said that he has had in excess of 200Meg between a column body and true earth, because the columns are anti-corrosion coated below ground level and this is not conductive.

To be honest I was amazed as I have only ever worked on old street lighting where this coating has obviously broken down, or was not present.

Ah yes good point Sidey, hadn't thought of that.

 

[Sidewinder]

I hadn't Sharp until a few weeks ago as I had never come across the situation!

There was me thinking the black bit at the base of a new post was a depth installing mark!! :innocent . Bleeding idjut! :slap
