Calling all Electricians...possible electrical issue.

[DaneGer21]

I just noticed this 10mins ago while looking at my apex. Notice one eb832 is reading 115v and the other is reading 120v.(see attached) The lower voltage eb832 is downstairs running my sump/main equipment the higher voltage one is upstairs running power heads/lights. Each eb832 is on a different circuit/breaker.

I’ve heard this can be a possible loose connection or bad connection, “usually” on the feed side of things. Or even a bad neutral/ground circuit.

Any advice of what to check? I’m very handy inside and outside of panels, but not much experience diagnosing things.

Or, should I call the power company?

Thanks!

Nope there’s not really a problem there. A slight difference in that voltage is just the difference of the two phases in your house. Equipment will continue to run fine and there should be no real consequences to that minimal voltage difference

Moments later with no heater running...

Ok thanks! I’ve always seen a slight difference, which I know is and will be normal. But I’ve never seen a 5v difference.

In addition to what the other poster mentioned, it's also possible that your 2 EBs have slightly different calibration, or that the calibration on one of them is wandering.
