where does it state in the code 02, 05, and 08 how many conductors to use for a feeder to a sub-panel? I've always thought 4-wire was required but I can't find it in the 02. Is there any application when you can use 3-wire? Does it matter if it's a seperate building as to the number of conductors required? I know now that you are required to drive ground rods if it's a detatched building, but does that mean that you can run 3 conductors instead of 4?
