BEST Electrical Multi-Meter that I use everyday!

It's because the neutral and ground buses are bonded at the sub panel that is fed by that 2 pole breaker. Whenever that sub panel has a load, the neutral and ground wires share the load back to the main. This is why all sub panels need to have the neutral and ground buses isolated.

I think you need to get an electrician out there.

Ground being used a neutral somewhere.

You have your equipment, grounding, conductor in parallel with the neutral downstream probably at a subpanel. It's called objectionable current.

That neutral wire is tied into the ground wire at some point. You have objectionable current on the ground wire most likely due to the undersized main neutral judging by your lug readings. You’ve narrowed down the issue to either that double pole breaker circuit, or the main neutral conductor of the subpanel, or both. Check all panels/disconnects. Hook up a wire tracer and see what you can find. Hope this helps I’m only a first year

I think a few problems. For one, that ground wire is probably being used as a neutral for that 50amp circuit. Then, the varying voltage issue is probably a loose neutral. Definitely undersized but I think a loose neutral is the problem.

Does anything on that circuit use a start/run capasitor?

Could it be a loose neutral wire or there is some leakage current

I was going to say that there is no neutral wire going to lug until you mentioned the undersized neutral wire did they land that on the neutral bar instead of the lug on top

You lost a phase and is running through the load and coming back on the secondly leg.
Or is just an imbalance within the conduit and voltage electrodes onto non-conductor wires

How far is the that load from the panel

i have a camper on a lake lot and if you do read the comments. i learned a lot! and id never run a wire that small and long to an rv running the ac unit. mine will heat the factory plug up so i cant imagine adding 100ft or more. seems like the fire hazard status would go up a whole lot!? my shop is running on a sub panel and its not bonded to the neutrals. i knew it was not supposed to be but never knew the reason behind it.

If voltages are uneven the cause is basically a bad neutral somewhere. If that is the main panel i would suspect an upstream fault. Ground is carrying the neutral current as best it can to the closest upstream ground (usually the transformer where neutral and ground are bonded again).

Let’s not forget that the neutral only carries back the difference. Not the total of both legs, but the difference between them.

There seems to be a problem on the circuit you turned off then on, my guess is you have a hot to ground fault with enough resistance in that circuit so as to not trip the breaker and it’s acting like a series circuit causing the voltage drop on what you called B phase. Notice when you turn that breaker off the B phase voltage returns to normal.

That breaker that you turned off might have a large load on it or something else is going on with that cercuit. That neutral deffinately needs to be upgraded also.

Considering it's a sub panel, i would guess that the ground is probably connected to the neutral.

Is an undersized neutral more than likely the neutral is burned up. Because it has been used based on looking. And your back feeding on that ground because you've lost the neutral. And drop that bus bar for the neutral to ground . Neutrals will carry a load when in use that's why I'm saying you've lost the neutral

IMO one of the problems is I refuse to allow wire nuts 'in' the breaker box. That to me is a sign of crap work.
