I have a warehouse-type space with 14' ceilings, and am updating the electrical for my workshop. Right now, I've got four workbenches that I move and reconfigure depending on what I'm working on for a particular project. Each workbench has 20A of power (each one has one of those 4' multi-outlet power strips), which I'm currently supplying via extension cords from nearby outlets.
In a perfect world, I want to get these cable runs off the floor and use a ceiling drop to distribute power. At the moment, I've got 4 lines running to a box in the ceiling, and was about to hardwire some 25' entension cords (with strain relief, of course) for the drops. However, short of zip-tying a mess of cords or wires together, is there any way to combine these four separate circuits into a single cable, then breaking them out into four separate curcuits again at the bottom? It'd be awesome if I could just wire four 12/3 runs into a 2 or 3 gauge cable, then magically redirect the electrons to one of four 12/3 edison outlets at the other end. But I don't suspect that exists. :)
