If someone is interested in a challenge, how about dropping in at Booth 1859, the NeutrikUSA booth and ask if they have considered making more USA friendly PowerCon and True1 cable connectors. The problem is with type SO 12/3 cable which won't fit, especially in the True1 connector, type SJ, no problem BUT no go on SO.
Someone, perhaps not me but others perhaps also have chatted with Leviton, Marinco and other vendor rep's about the limitations of the Neutrik plug over the years. Sent some advance copies and Bought some of the new Marinco alternative, not completely inpressed with what design they have for it, but doing both brand now in neither preferred overall. Wish they did the True 1 also.
I have seen Powercon type connectors mounted on SO type cable from fixtures - China. Never really looked into them much as they have been noted on the SO cable to come un-locked at times. Mostly recycled them as with almost all cable/fixture whips as almost all are too thin a gauge for power feed thru (idiot proofing) and most are not rock and roll in being broken down in jacket type by DF-50 fluid and or cold. Yea, 12/3 SJOOW cable non CE standard cable is the best. And them darned pozi-drive or T-8 screws. "Silly American" there is no problem with XLR male shell locking slots breaking I was once told. Really told this.
