15 amp vs 20 amp

@jea48 always makes sound technical explanations

On a side note, you would be quite surprised how few amps you really draw if you were to measure your wall outlet to the system running at a high level. In the past, a similar system to my present was drawing less than 5 amps. So, headroom is very important, but 15 amp products are not going to impede your system.

@mlapenta Yep, cables do matter.

FYI: Kil-a-watt will capture peaks. Didn't use a handheld meter. Certainly understand that 15 amps will never be reached even with transients.
