We found a couple of lighting panels today that service strickly electronic lighting. Circuit breakers {single pole 30a } hot to touch or some warm. After further inspection of the panels we found the following L-1 - 128A
L-2 - 125A L-3 - 118A , the neutral was some where around 60a . The circuits are using 30a single pole cb and pulling up to 22 amps a circuit. Each lighting section uses a 30a twist lock to a 120v plug to supply power, the plugs are burning up at a fast pace , both male and female plugs. There are 20 ballast in each section ,1 t5 bulb for each ballast.
Anyone have a reason the why the plugs are burning up?
Panels are three phase 120/208 with a 200a breaker.
