Breakers tripping when power returns.
It is possible that the electric utility has a problem in their wiring. Specifically if the neutral or ground are not well connected, reconnecting the power from upstream could cause lopsided voltages due to a wandering ground.

The easiest diagnostic would be to request the utility to verify their wiring which they ought to do for free.  If they won't or can't, you can rent a power quality analyzer and see for yourself.


Be sure to test nominal power and during switching "off" and then "on" your main breaker.  If the analyzer shows electrical problems, provide the details to your utility and they should fix it pronto.

If the test shows a ground problem, it might be on your end.  Then it will be up to you to fix your grounding system
