Wait and see if anything trips now that the work has been completed.

They might have used an edge sander on one of the circuits.

when you say 'bathroom breaker', do you mean the breaker in the main box for the bathroom or the GFCI outlet in the bathroom itself?

And is the 'bathroom breaker' a GFCI breaker (it has a TEST button)?

Thanks to you both for your replies. So far so good today. To answer your question weedmeister, I meant the breaker in the breaker box that is for the bathroom. It is not a GFCI breaker. It just seemed strange to me that heavier usage on two other breakers would cause another breaker to trip. I tend to worry about anything electrical.

I suspect that they plugged something (heavy load) into the "bathroom circuit", the breaker tripped, and they moved on to use other receptacles. They came to work on floors, not to talk to you about tripped breakers.

They may not have been there to talk to me about tripped breakers, but I recently mapped all of my circuit breakers and I know exactly what is on the bathroom circuit breaker. Only lights and outlet in the bathroom. Said bathroom was locked the entire time they were here with my pets inside, so there is no way they plugged anything into the bathroom circuit. But since nothing has tripped since yesterday hopefully everything is ok.

The vibration from the floor refinishing may have shaken something loose in the bathroom circuit and created an intermittent short. It wouldn't be a bad idea to open up the boxes on that circuit and have a look around.

Were your pets using the whirlpool tub while you were away?

lol. No whirlpool tub I am afraid. But since there may be something shaken loose, I guess I better get an electrician out here to take a look, if only to put my mind at rest. Thanks for any and all info!
