Hello all. Newbe here. I have old Quincy 20hp 3ph 460v horizontal compressor.  It is our back up compressor and i have ran it w/o a starter or pressure regulator to check it out. I will build control panel for it as soon as i can find parts. I need 3ph 460v 20hp magnetic starter with overloads. I need pressure regulator and a few words of wisdom please and thanks in advance.
