So I noticed I had 4 x 500W-PAR56-MFL circuited on a 14AWG two-fer. This has me uneasy, so I removed the two-fer this afternoon. Especially because that breaker keeps tripping. Really one of my biggest concerns is having anything (except for instrument whips) be anything but 12AWG, considering we have all 20A dimmers. Too often are two-fers used as 2' jumpers. Anyways, I'm wondering if these are a standard. The craftsmanship on these two-fers far surpasses anything I've seen at my theatre before, so I think they were professionally wired. (Some sort of locking washer on the set screws, crimp terminals actually crimped on, working strain relief made out of something I'm not familiar with [friction tape?], plus these look relatively new, no pitting on pins, no gaff-goo) Thoughts here, guys? Edit: AND gals, I'm not from the 1900's!
