Transfer Switch Question

I have a 100 amp service with 12 circuits (6 on each leg) Two circuits are tied together for the A/C service.

I want to install a 12 circuit transfer switch so I can intermitently run any of the circuits. Right now, I only have a 3500 watt generator but plan on getting a larger one within the next year or two.

Most of the transfer switches that are rated for 3500 watts only have four circuits. I understand that I can't run all of the circuits with the 3500 watt generator.
My Question: Is it legal to install and operate a transfer switch with a generator that produces less power than the rating of the transfer switch?

Thanks,
Phil

Yes, however you will probably have to change the input connector on the transfer switch.

racraft,
Actually, I'm thinking of hardwiring the transfer switch to a power inlet box in my garage. Then I'll run a cord from the generator to that inlet box.

The generator I have now is a 3500 watt Generac and requires a four-prong "NEMA L14-20P" type plug. Do the larger generators have a different receptacle?
Thanks,
Phil

A generator that supplies more than 20 amps at 240 volts will have a different connection on it.
