The question that was ask, was how do you shut off the hyd pump if it runs
away, if you can't reach the 50 amp breaker. I can reach mine, but it is a
standard breaker (not pull off = expensive).
1: The mandatory drop gear testing will make the pressure 0 and your pump
will run continuously, which will make it overheat - the drop test is slow.
If you use the factory intermediate duty breakers, they will often fail
during a drop test.
2: Any breaker point can hang leaving the pump running which will fill the
cockpit with smoke, this causes a situatuation that is much less esthetic
than an extra switch/breaker. Ask Don Goetz.
I think I have a very esthetic ( inexpensive - aluminum) panel, and it has a
way to shut down the hyd pump. If any one wants a JPG tell me.

The little bitty wires to
the relays are protected by the fuse. This fuse will protect the wiring
to
the relays. I can't envision a situation where I would want to disable
the
pump but keep the relays powered, so one breaker cuts off everything> Why
a fuse and not another breaker? I have a Control Vision power
distribution system mounted to the slanted panel on the old-style 320/360
panel, plus separate breakers for hydraulic pump, pitot heat, and main
power
to the power distibution system. There's no room for a pump relay circuit
breaker, but there is room for a fuse. It would be aesthetically
unpleasing
if I mounted another breaker elsewhere. Otherwise, a breaker would be
fine.
