I am making a stage pin quad box, but I'd like help before I start. Since all in/out connections are stage pin and therefore 20A, I know 12/3 SO or SOOW cable is required. Other than that, I need a stage pin plug and four female surface-mount receptacles. Are there plates that will accept stage pin sockets AND mount to a 2-gang box? Are they out there/legal? To boot, I have just read that metal quad boxes are a no-no for portable distros. (This makes no sense to me, but I'm not going to raise a stink about it.) Thus, what is a good, inexpensive solution? (And, where would I buy female stage pin outlets?)
PS-- An alternative option is to have one "half" Edison duplex (20A) and the other half stage pin.
