So would this reset immediately or not reset at all?
Not at all, it has to be flipped off before you can turn it back on.
When a breaker pops the switch moves to the middle, to reset, you have to turn it all the way off and then back on. If it's in the middle and you go straight to on then it's just springy and nothing happens, and it moves back to the middle.
So yeah, ruins the joke but nothing's compromised here.
That actually is good context tho. Ive sometimes turned a switch from middle to on and wondered why it did nothing and then turned them all off and on and it worked. I assumed i was flipping the wrong switch
Thanks!
I wouldn't say you ruined the joke but used it as an opportunity to teach. Thanks again
Would not reset at all.
Basically, the breaker has an internal switch and an external operating handle. When it trips, the internal mechanism of the breaker disengages the internal switch from the external handle, and flips the internal switch to its open position. The handle can't toggle the internal switch while it is disengaged.
To re-engage, you have to move the handle to the full "off" position. The internal switch re-engages the handle, and the handle can now toggle the switch again.
This breaker cannot be shut off manually, nor can it be reset manually. But, it can still trip in case of a fault.
It's kinda like if you have a pushbutton start car, but you drop off the passenger who has the key fob. The car will continue running until it is shut down or stalls out. But once that happens, you can't restart it without the key fob.
Neat, that's a really clever mechanism
