I don't see anything identifying to know which breakers are on which phase. Is there a way for me to figure this out without hiring an electrician? We've had bad luck with the last two we've hired.
Thanks for the idea. I'll do some more research on this as it's new to me.
That's a bit of a hard one.
Don't know which country you are in and what type of breaker box you have.
Most of the time the breakers are distributed evenly, so the first one is phase 1, the second one phase 2, the third one phase 3, the fourth one phase 1 again and so on.
Only way to make 100% sure is to open up the breaker box, and honestly, not to be advised (even strongly against) if you are not an electrician!
Once you know which breakers sits on which phases it's rather easy (but a bit time consuming). You shut of all breakers for phases 2 and 3 so only the breakers on phase 1 are on.
Then you go check all the power outlets which still have power (small table lamp or so), so all of those sit on phase 1.
Then repeat with all the breakers for phase 1 and 3 off, only phase 2 on, and one more time with phases 1 and 2 off and only 3 on.
