What is wireway cable?
A wireway is typically produced as a metallic or non-metallic trough with hinged or removable covers, so that the cables contained are well-protected but still accessible . The high cost of manufacturing and installing wireways limits their use to small sections of cable management systems, while most systems primarily consist of cable trays, conduit, and other types of raceway. When connected, wireways must be reinforced using special fittings and gaskets between sections.
What is a NEMA wireway?
Many covered wireways, as well as most enclosures, are often provided with a NEMA type, which is standardized by the National Electrical Manufacturers Association NEMA ICS 6 standard. NEMA types are numerical values (sometimes qualified by a letter) which describe an enclosure's ability to protect contents against various types of environmental hazard. The table below shows common NEMA types along with the hazards they are designed to withstand. (The 'N' in the 'Chemicals' column indicates that NEMA 5 and 12 enclosures are only effective against noncorrosive chemicals.)
Why are wireways important?

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.
