Circuit breakers can be tricky.. One thing they do is an invisible trip.. THey LOOK like they are on but if you touch them they feel different.
And that's how I check 'em.. By Touch.. Or by cycling..
I kind of developed this habit cause I had Push-Matics in my house till the last few years... And those are very hard to read by any other method. (I put in Square D when I got the motor home, also put in a generator transfer and inlet.. Wished I'd done that sooner.. Was nice haveing a nice warm house on New Year's Eve, in Detroit when Edystone,, er, Detroit Edison /DTE Energy let me down).
