"AS for a reversing starter as a transfer switch. The stinker is you will have to feed each contactor from the bottom and take power to your main house/building/service panel off the top of the contactors."
why would i have to feed from the bottom?
and how do i feed from the bottom of a type 3 allen bradley when the feed and output terminals are all out the top?
even the conventional contactors can be configured and fed from the top and output'd from the bottom, it is a simple matter of reconfiguring the wiring, is it not?
if not why not? basically you have on each two contact's with a bar that connects the two, so i see no reason that one could not connect either way, i dont see how the contactor can tell which way is which?
as for the neutral being switched or not, why couldnt i just use 2 of the 3 poles, or in other words leave the center unswitched if so required
anyone else:
i might also mention my application perhaps it makes a difference
i am planning off grid, so the two feed sources are
1. from an inverter
2 from a generator
inverter feed one contactor, the generator the other contactor
if the generator comes online, it switches the reversing contactors so the inverter is off line and the generator is online,
when the generator goes offline the inverter switches the contactor backonline , further...
all the power apparatus will be seperate from the house panel, so the house panel has only one feed comeing into it, and as far as the house is concerned
it has no idea where the power is coming from, so
i should bond everything in the power house to ground, and bond the house panel to ground
also where i am building there is no inspector or overseeing authority to inspect anything,
so basically the way i see it is, if i follow national code in the house, then i am safe with my house no matter if the house is inspected or not, and
the power house being a seperate system if wired to code should be safe no matter if inspected or not.
basically i have two seperate systems that if inspected are the same as and should be viewed as two different systems, correct?
