I was at a video game convention recently and came across these portable "mega power strips", for lack of a better term. It looks like a subpanel with a bunch of outlet boxes attached, connected to a three-phase 120/208 outlet.
I'm just wondering if these things are legal. I've seen many photos of "home-made power strips" that use outlet boxes derided in the violation forum, and got curious when I saw these being used to provide power at the convention center.
The photo is attached; hopefully it comes through okay.
