Here is the one I bought. Rated for 20Ahttp://www.amazon.com/gp/product/B00917YZMW/ref=oh_details_o02_s01_i01?ie=UTF8&psc=1
This is what I use (/will use when it arrives) for the power to my control box. My element has a 12ga power cord that connects to the element inside a gang box. On the other end, the prongs connect to an outlet built in to the control box. No live wires!
However, I do agree that the twist lock receptacles are safer and look nicer. unfortunately, they are more expensive, but it depends what you're going for.
