Reno- I happen to have a 13kw generator feeding an automatic transfer switch rated at 100a. Integral with this automatic transfer switch is a MLO panel with 12 spaces. There is no main in the transfer switch nor is it SUSE rated. The other side of the transfer switch is fed from a 60a. breaker in my 150a main panel. When running on generator, my range and dryer and several other circuits are not connected to the generator. I see this as code compliant. As for the exercising the generator, the unit starts every week and runs for 10 minutes to circulate the oil and charge the battery. The load does not transfer during this exercise cycle. On this generator panel is my central air, furnace, microwave, refrigerator, two freezers and three lighting circuits.
