Hello I was running fibre on some telephone poles and touched the messenger and got a shock. It Wasn't huge but definitely noticeable. I'm in an insulated bucket though so it could've only traveled through fingers. So I wanted the ability to check for voltage on the messenger line. So I got a ncv pen but it doesn't tell me anything useful. You can get a reading 6ft away from a dead messenger. Likely due to the transformers/current going through the mains.
Just wanted to be clear on my terms and what the poles are like here in Canada.
the messenger is a steel wire to support data lines. (fiber and copper). It is connected to earth every few poles.
The nuetral is at least 1m above the data lines, although a few poles from where I got a shock the nuetral appears to be touching the messenger.
The primary is above the nuetral.
So what do people use to test this? Will a clamp meter do what I need to keep me safe?
