Try the experiment yourself. I'm willing to bet a $20 home depot receptacle will sound just the same as anything else on the market.
Why wouldn't it?? 20A, 12ga solid copper wire. I would far more concerned about quality of power coming from the line than a receptacle. Maybe take a look at the voltage sag at various times during the day and night from the public line. LOL I was sure surprised at that and I'm in a very populated area (10M+ people in a 30mi x 80mi stretch)
Outlet Question
Could not find category for outlets so I am asking here. What would be good outlets to change too? I had hospital grade from Home Depot 20 years ago but left them when I moved. Is there any good outlets for about $20 U.S. anyone can recommend? I don't want to go crazy but get something better than what is stock on homes built in the last 4 years. Any suggestions would be great!
