Hi, Mechanix~ My off grid project needs dual 40kW diesel generators with easy manual selection between "A" or "B". The output from the manual switch would feed AC into a set of XW Pro inverter/chargers.
I seek a 200a manual xfer switch that can also changeover the 12v+ generator automation wire with the same handle. Schneider DTU324N is 3 phase (solid neutral) so that does get me a third blade but since the trigger wire is only a few amps this p/n seems like overkill on size/weight and on cost. The manual switch unit doesn't need to make or break live power because folks always tend to shut down any nearby noisy engine before they do any switching. We also don't need 100k short circuit current rating because the machines can't fault as big as grid power can. Non-fusible seems best b/c each genset will have a 200a main breaker. I'd prefer to buy the switch inside a NEMA1 enclosure rather than getting a bare switch that would require me to mount it into a housing. The project won't be code inspected, so thanks in advance for any suggestions. The Wrench List is the Bomb!
