Hello:

Is it possible that when a circuit breaker in a service box opens due to a
short in the circuit that it is controlling, that the lever does not (also)
move to the other position ?

e.g., that there might not be any visible indication that it has tripped ?

If so, is this fairly common with circuit breakers in a house service box ?
Likely ?

Why ?

Thanks,
Bob



It all depends upon the mfr and the age of the device.
Some ancient ones were designed in a way that the handle
doesn't move to a "Tripped" position.

Some move all the way to Off; some to a center position.

Some must be moved to the full Off position before
they can be reset to On.
