I have a garage wiring project to do in the near future. Using the book Wiring Simplified 41st Edition as a guide, it highly recommends the use of 12 AWG wire and 20A breakers for 110V circuits.
So, jumping in head-long, I bought a 100A loadcenter for the garage, a 1000 ft spool of 12/2 wire and various 20A single pole breakers. When I got to lightswitches and outlet receptacles, I became puzzled.
It seems that outlets and lightswitches rated for 20A are harder to come by, as I could find none. The regular 15A outlets say "for use with 14 or 12 AWG wire." Why would they say this on them when 12AWG wire is used for 20A circuits?
Do people typically use 12 AWG wire with a 20A breaker and a 15A receptacle?
