Hey All I'm wondering what is needed to take full advantage of 20A electrical. Do you need to replace standard power cords for amps in order to get the extra juice? When running a power center (surge, filtering) does that need to be a 20A model, and if not are the 20A circuits basically a waste? They're already installed so it doesn't matter one way or another. Just wondering if I need to worry about spending big cash on a 20A power center (ex. Furman Elite-20PF) or if I can get away with a 15A. Thanks.
