I'm installing overhead raceway for aproximately 50 machines in a machine shop.Most will be on 20 amp three pole breakers.I'm going to be running 2" EMT from the panel to the raceways.I'm thinking about running a #6 ground wire from the panel ground bar to the raceway,and installing(bonding) a terminal ground bar inside the raceway.From the ground bar in the raceway I would run a #12 ground wire to each machine saving me time and wire.I'm thinking this is legal
Any and all comments are appreciated.
