I'm still looking to start my dual 2000w control panel, hopefully soon.
I'll be honest, I'm not hooked on any particular design, I just want functionality. That being said, if the contactors are there only because of the choice of the pushbutton switches, do you have a drawing that uses switches that can handle the load going to the elements, which if I'm understanding correctly, eliminates the need for the contactors? Seems as though that would free up space in the control box and simplify the wiring.

Generally they spell it out and I take the time to draw a diagram to help them. P-J
