Here's the details.
I am renting an office in a warehouse. I need to installed 2 - 220 20amp outlets for my computer servers. the length of the run is 76ft. there is 4 90 degree bends in the run. All the existing electric is run above the office ceilings and is in rigid or flexible metal conduit. I have run a few 110v circuits but never any 220v.
do I run one 220v, 40amp circuit or 2 - 220v - 20 amp circuit.
what kind of conduit ( pvc, rigid metal, flex metal)?
what size conduit?
What size wire?
solid or stranded wire?
if i run 2-220v, 20 amp circuits do i run two whites and two grounds?
my current thinking on this is to run one 220v, 40 amp circuit. the run will terminate on top of the wall above where I need the outlets. i would split the circuit there and run the two legs to the outlet boxes in the office wall.
I would use 3/4" pvc conduit and pull 4 #08 wires, red, black,white and a ground. I would use 3/4" flexible plastic conduit to run the outlet legs down the wall to the outlet boxes.
any and all answers and comments appreciated.
