Protect wire and cable from dust, dirt, and oil/coolant dripping— this raceway is rated NEMA 12.
Why use more than one channel in a raceway?
With more than one channel, this raceway allows you to separate power and data wiring to prevent signal interference.
What is wire trough?
Wiring Troughs are durable and economical continuous hinges that provide smooth and pivotal action and optimal axial rotation. They are traditional clamps for rugged, durable and proven performance with a separate padlock hasp and staple for security.
What is a metal wireway?

How many square inches are in a 4x4 wireway?
All of that said, a 4x4 wireway has a 16 square inch cross section 20% (max fill of any cross section) is 3.2 square inches. 350 THHN has an area of .5242 square inches per table 5 in the back of the NEC. So 16 of them equals 8.3872 square inches. Not to be condescending, but the rest of it is math. Any of us trying to size these things should be capable of doing that. Look up the area of each conductor size in the tables, multiply by the number of conductors, add them for a total, multiply by 5 (5 x 20% fill) and then you have the minimum cross sectional area of your wireway.
How many conductors are in a 400A switch?
The wireway will consist of 4 sets of 350mcm copper conductors extending from the switch through the trough. Off of that I will have a 400a and 200 tap. (400a panel tap will be made with 4-3/0 and 1 # 3 ground; 200a panel tap to trough will be made with 4-3/0 and 1 #6 ground)
Do 350 volts go straight into unitaps?
If the 350's go straight into the unitaps, the tap conductors will have to do a U-turn, thus counting twice towards cross section fill. You'd get a much cleaner install if you used dual entry tap block (wire can enter from either side). Also remember to alternate between line and load with adjacent entries.
