Thanks for the confirmation.OK, I just went and measured it (MB3CD). I have a fixture for measuring current in AC-powered devices and an RMS clamp meter. Sustained current with both motors on is 20.1 Amps.
So I'd even go a little further and say a dedicated 20A circuit is necessary. In fact to meet the NEC de-rating recommendation you'd be better off with a 30A 120V circuit.
(Many don't believe this to be true.)
