REFLECTOR: Gear Pump and Gear Ctrl Circuit Breaker

[jewen at comporium.net]

If both the control circuit and pump motor are on the same circuit and you
have a motor failure that trips the breaker (short circuit in motor
windings to ground for example) you will not have the indicator/warning
system that tells you the gear is in the down and locked position.  In my
installation, I have a seperate gear control circuit and gear motor
circuit.  In my mind the benefits are the indicator / warning system will
still function if the motor fails and the motor's breaker trips.  I would
not gang the breakers (mechanically tie the two breakers, like a 2 pole
household cb.)  Ganging the breakers would defeat the benefit of making
the control seperate from motor power, hence no down and locked
indication.  I would like confirmation that an emergency gear extension
fully lowered the gear.
