ECN Forum Forums General Topics of the Trade General Discussion Area Why not 2 grounding screws on receptacles?

A little confusion for me. ..nothing new.

Is a 15 amp receptacle rated for the feed-through of a 20 amp circuit??
My belief has been that a 15A circuit could be fed through the device, but not a 20A.

Not important in my world...I pigtail them regardless...S
