Current Draw for LED Projects I am working on a project with LED strips that would consume 12V and 20A. The problem is that the household wall outlet limitation is 15A, and 20A current draw would potentially start a fire. I have been searching for tutorials of large current LED project, and none of them really addresses the current draw problem. 

I found an adequate power supply. It is Meanwell RSP-320-12. http://www.mouser.com/ProductDetail/Mean-Well/RSP-320-12/?qs=Uzd%2Fwh%252bZzhBChmc2p7rgKQ%3D%3D.

How can I make it work with a 15A wall outlet limitation?

Thanks in advance!
Drawing 20A on 12V means 240W which on 110V is 1A and a bit (a bit more once you consider efficiency of the conversion). 

The spec sheet of the power supply you linked says that it will draw 2.7A max on a 115V input.

The power supply will convert the high voltage low amps into low voltage high amps.
