What did YOU do today?

[Sudo]

That sounds like a bad/loose neutral.

I was going to say the same..........

is it the main panel or a subpannel. Keep in mind....You can't have a bonding screw in the subpanel and the neutrals HAVE TO BE SEPERATED FROM THE GROUND WIRE'S . Meaning , the Neutral Wires can't be in connection with the sub breaker panel.

Sounds exactly like what happened when my parents' house had a bad neutral between the meter and the house.

Sounds like a few of us have experienced this.

Probably. If those voltage readings are at the panel, that narrows it down to the neutral bonding screw in the main panel or a loose connection at the ground rod outside.

So far this morning, I’ve finished off 2 twelve ounce coffees, a pack of Pop Tarts and removed a cover from a fan so it can be pressure washed. On to the next work orders. It’s triple time day for a 12 hr shift.

And repaired a few motor disconnects that had loose knife blade connections causing overheating.

Easy peasy. Just de-energize and replace the knife blade assembly

We'd end up bending it back tight. Probably live...

That’s no good. Once the fingers have been overheated, they lose their temper and will never grip tight again. Squeezing them doesn’t work because they are no longer springs. This causes a looser connection and more overheating with more thermal expansion and contraction making them even looser yet. Then higher temperatures… It’s a downward spiral that ends in fireballs and downtime. Once identified as overheating, the only solution is replacement. We do thermal inspection every fall and make necessary repairs ASAP. The IR camera doesn’t lie.
