So what does the electric load detector do specifically?

1.Similar to the fusible link in a domestic car, it pops if
an overload takes place?

Or 2.Cut off all electricity if an overload takes place?

If so, a way around that would be to put in a reset switch
or a manual overide...............or even put in a real
resettable circuit breaker..........maybe even as part of
an anti-theft switch......and mount it under the fuse
box out of sight.

Does the manual give us any insight? -Bob
