Quoted from Manimal:

If I had to do it over again, I would use what Monster_Bash suggested, but take a step farther. The type of setup he mentions is commonly used over server racks. There is a twist lock plug in the ceiling and then a heavy cord drop to a Power Distribution box that has the capability to support 4 smaller power strips that mount in the rack. I would run 4 or 6 pins off of every PDC.....that way you only have to pull one plug or throw one switch to disconnect a group, and each strip also has it's own dedicated switch. You usually order the PDC with the strips included, and I am betting it would be cheaper than having a plug installed for every pin. The PDC is very thin and flat so it fits in the server rack, and it comes with a variety of mount adapters so you can mount it to the bottom of a machine, a wall, or wherever you want it to be.
