What is the highest voltage which can safely be gloved while live?
Max hot glove voltage

AFAIK, we had it used on our 34.5 kV lines (Class 4 gloves).

I’ve used 15kV rated gauntlets but it was only as a precaution knowing the circuit was dead. They’re impractical if you’re doing anything that needs dexterity.

Ok- so 34.5kv is ok to hot glove. I know 12.47 is but unsure about anything above that as I keep finding conflicting info. FWIW linemen do not like 34.5kv, but unsure if legit or just urban legend of that being more dangerous.

No grounding down?

No, we regularly tested the MV distribution system cables after they were proved dead. It was a precaution.

Always ground though, you never know when it could become energized... if it ain't grounded it aint dead.

How do you test insulation when the cable is earthed/grounded?

36 kV is the max for gloves.
But there are companies working 46 kV hot as well. I haven't watched, and probably don't want to, but I would bet you they are gloving it to some degree.
They probably consider they limit gloving to no phase-phase exposure. Not sure if that is a legit method or not but the glove is good for the line-ground on 46 kV.
They work 500 kV hot also but not a gloving technique.
Not giving my dog hot gloves..................
The basic thing is that there is no such thing as "a very important job" that you can't do them safely--> de-energize them!
But your quickness in restoring power could mean saving the lives of others, so it's your call.

I’m registered with my supplier as “at risk” if power has to be cut for more than one hour they have to provide a generator.
You are correct of course. It's a serious issue and my comment was light hearted. My dog is Max you see.The basic thing is that there is no such thing as "a very important job" that you can't do them safely--> de-energize them!

A guy I worked with for many years used the SIDE rule.
