Just 'cuz it's in a panel? Or does any dead-ended energized wire drive you bonkers?

Anything I don't understand drives me bonkers... just because I figure if I don't understand it, there might be something somewhere else that's going to get me in harm's way.

You've got a point though... I think it's the knowledge that there is a live wire in the panel that is dead-ended that would seem odd to me, because why would it be there in the first place unless something stupid/goofy had been done? On the other hand, if I was new to the situation I wouldn't know that it was energized, and I wouldn't take off the wire nut to check either, so I'd be in blissful ignorance and think it was a mothballed circuit that went off to points unknown.

I'm neurotic, what can I say?

I ditto that, and just to make Frizbeedog start barking, I'm posting this:

I found one,simular to this problem.Whoever changed kitchen receptacles didn't break off the hot side jumper and this was a split receptacale fed by a 3 wire circuit.The installer heppened to use a tandem breaker,where both circuits were on the same leg.2x20amps=40 amps on neutral.

PC answer is.

An experienced qualified electrician would know the minute he put a tester on the conductor what the issue is. I WOULD SURELY HOPE.

Harm's way......YOU HAVE TO ASSUME ANYTHING YOU HAVE NOT TESTED IS ENERGIZED.

:-? I found today a circuit powered by two diferent CB,
Any Idea what is happenning here?

Sounds to me like the intent of the original install was for two different circuits. Capping one in the panel could put a pile of openings on one circuit leading to possible overloading and tripping.

I would identify the two ungrounded conductors in the panel and follow them out. Do they leave with one grounded conductor?

Find the home run box, fix the joint and trim the panel correctly.

Or just cap one off in the panel.:rolleyes:

Thats a pile of assuming.

On your own time? The bosses? Customers?

Just wondering, do you let them know and choose?

Which is perfectly safe ...... practical safeguarding etc.

First place to look: Any 3-or-more-gang switch boxes. 99% guaranteed that's where they're tied together.

If that wirenutted conductor abandoned is hot,I would consider it a violation especially to the next guy who might grab it. (Hot because of a backfeed.)

Why would you "grab it" (figuratively speaking hopefully!) unless you knew where it was going? Otherwise, it's going to points unknown and is of no value until you determine where the other end is.

Of course... my point is that something weird like that (and it is weird I think, even if not a violation) would make me wonder what other odd situation might be there in the same location that could trip me up. Everyone likes to be methodical and careful, but I think errors are more likely to occur when there is an unusual configuration (like a California/Chicago/whatever 3-way).
