Russ White is spot on with the delay of the XFER, it is to prevent the load being applied before the set is ready.
Lyght Power Systems is making a direct replacement for the Todd product. It uses 75/pole contactors mechanically interlocked, and rated for up to 18KW. I have sold a few of them and they look to be well made. It is enclosed in a NEMA 1 enclosure. Let me know if you can't find one.
A word about our electrical systems: The wiring from the generator, shore, & to the distribution panel in all the Newells I have seen is #6 which is rated for no more than 45A (NEC article 400.5a) and protected by 50A breakers. This means the maximum load carried by our electrical system is limited by the 50A CB to 12KW. Why do we have 20KW generators? To handle the inrush currents required by the motor loads, in our case the AC compressors. And we need it too!! Newell has toyed with 15KW engines driving 20KW rated generator ends, invertor systems with generators for battery recharging, and a few other systems. They are now using Martin Diesel sets (the best in my opinion) rated at 20Kw and the engine HP peaks at 24KW.
