Is there any way to test a breaker?

Fisher said
A breaker has 3 positions. On off and tripped. tripped is in the middle. easiest way it turn breaker off then turn back on. what is your voltage in the USA? 240 volt? here we are 208

Is that in Imperial or Lucas volts? :poke:

J/K. It's 120/240. I am aware of how a breaker works. I need to know if there is a way to see if it is holding the proper amps.
