I DONT KNOW ABOUT SWITCHING 3000 VOLTS. BUT IF YOUR JUST SWITCHING 30 AMPS @ 240 V ON PRIMARY.I WOULD USE A RELAY AND PUT A SMALL SWITCH ON FRONT PANEL TO TRIGGER RELAY. CHEAPER THAN A HEAVY ROTOR SWITCH. LESS SPACE ON PANEL IF THAT IS A PROBLEM. --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html ---
