Went to a job today and noticed a length of metal conduit going across a pathway. The metal conduit is not earthed.

I just wondered what people’s thoughts were as to weather it should be earthed being an extraneous conductive part? It’s fixed to the concrete floor and if there was a break down in insulation there could be a potential difference. If you do bond it could it be introducing a risk?

Sorry exposed conductive part ?

What's in the conduit, how did you know it's not earthed??

It’s got a 6mm tne in it and you can visually see it’s not earthed. It’s surface mounted external to the building. Giving mechanical protection across a pathway.

OK thanks, , ,
