Wiring electrical outlets - 12 gauge wire, 20 amp breaker, 15 amp receptacles / outlets

get rid of the back wired outlets. you are just looking for trouble. sure its a pain to loop the wire ends for around the screws but you are better off in the long run. those beryllium springs loosen up and those wires can pull out!

 

I agree with Hayzee. NEVER use the stab in's. And if you use 15A outlets on a 20A circuit make sure you never exceed 15A over the entire circuit. The 15A rating applies to the entire outlet, including the strip between the screw terminals. An overload will cause that outlet to catch fire. Also do yourself a favor and do not pigtail the outlets. Power in on one set of screws, power out on the other. Pigtails with wire nuts are just one more connection to fail over time. It's electricity. Do it right the first time. Personally, I would always use 20A outlets on a 20A circuit because you never know what the future might require.

 

Around here, #15 wire is used only for lighting and #20 wire is required for outlets. IMHO it is well worth doing right. I always wrap the wire around the terminal. It takes a bit longer, but the connection will last.

 

I used to wire houses with a combination of #14 and #12. I found it cheaper in the long run to stock just #12 romex, then if I needed something larger, just to go get it.
