Auto Reset Circuit Breakers
Have been told that the electrical motors on Lippert Stab jacks should stop when the motor current rises causing the 12VDC auto resetting circuit breaker to pop (or you take your finger off the button...

OK, my bad.
All these motors stop so fast; I was sure there was an auto-cutoff switch involved (I had been told earlier that it was the auto reset breaker).
But I just checked the stopped awning motor with my clamp-on ammeter, and it was still drawing 9A. So it was "stalled", not "off". Of course the current went away when I released the manual button.
It's harder to separate the wires for the Stab Jacks to measure current, but Lippert Tech support told me the reset breaker is NOT used to stop the motors. Sometime I may double-check that, same for the Slide. I expect them to "stall" just like the awning motor.
This is consistent with what most of you are saying. The motors quickly stall (stop, but with current still running through them) and are not auto-switched off when the limits are reached.
Some motors like the tongue jack and some slide motors may be exceptions; these have an auto-clutch mechanism that you can hear operating.
Thanks for all your help. But it still leaves me with an over-energetic slide motor ripping up its drive shaft coupling. That's another issue though.
