I have flourecent lighting @120v and 26 amps using 30a 125v twist lock L5-30 on a circuit that has 180 hz 24/7 . Using #10 thhn wire on 30a cb. The circuit is drawing more then 80% of the 30a cb. We have 5 circuits out of the 18 that are 180hz. 25% of the ballast are electronic , It is a major job to try and split the circuits up to smaller loads. Tried to replace the qo cb with 100% breakers but sq d said they don't make them . Would any one know if the twist locks are rated at 80% or 100% ? A few of them are burning apart at the contact point. Any suggestions on correcting this ?
Most of the cicuits are about 22a. We are planning a overhall for the lights next year so have to make it by for now. Also the ballast was oringally magnetic till someone had a bright idea.
