No, it probably doesn't. And the problem isn't what's coming from the power company anyway.
The problem is that his neutral connection is bad.

I believe I mentioned in a previous post that the neutral connection in
the meter base could be a problem if it's loose.

I believe from the tests he performed the problem was isolated to be
between the subpanel and the main panel, not between the main panel
and the utility. He had normal voltages at the main panel.

I didn't see that post but it makes perfect sense. I'd also wonder if he was using a breaker as a switch to feed his out building. If the breaker isn't switch rated, one of the contacts could have burned. I've been able to track down problems like that with one of my infrared thermometers and my ultrasonic leak detector which allowed me to hear the sizzling contacts. In the late 1980's I was working for an electrical contracting group that had gotten into a new field of service for business and industry where we used thermal imaging cameras to check all of their electrical panels. Bad connections and defective breakers showed up very quickly. A problem I've seen more than once is caused by using a circuit breaker as a switch when it is't rated for that kind of service. Voltage drop across breaker contacts would be one of the first things I'd check for when there's an imbalance and no obvious indications of loose connections exist. Anyway, It's been quite a while since I've done any field work. ヽ(€¢€¿€¢)ノ
