aldav53,
I believe the thought is a 15/20 amp feed-thru rated at 20 amps won't have an appliance plugged into it that has more than 15 amps. If is it rated higher than that it would have a 20 anm male cord end and require a 20 amp receptacle. Yet the circuit will still be #12 good for 20 amps...if that makes any sense. It's starting to not make sense to me!
