Let me add a few more.
The standard 15 amp "outlet" will not accept a #12 wire as a plug in, the wire must be looped around the side screw, which on a #12 is a PIA.
On the 20 amp outlet it's designed to accept (8) wires stripped 1/2 " under 4 screw plates.
Besides the outlet comes in TR version and WR - combined, tamper resistant & water resistant approved
All this protection for only $6.79 each outlet will surely let you sleep soundly at night, while operating continously with a 20 amp load.
Cheers ottct
