OK - living in the Northest USA is beginning to suck!!!

Given a standard SquareD main elec panel which include a main 200amp
breaker with the breaker in the OFF position, is there anything/anyway to
monitor the incoming line for energy?

Ideally one could install something across one or both of the lines that
glows a neon or led when energized.

Of course I'm being lazy as I'm running on generator. But with all the
outages this year I'm getting fed up with killing everything and retrying
the main, back and forth, back and forth, etc.

Ideas? Thanks

Ed: you should go back to Tuscany. I bet they have power there!!!
