I have a bunch of Square D 4"x4"x4 ft wireways laying around that I would like to install in my shop for running electrical wires. The wireways are nice because you can have up to 30 current carrying conducts in the wireway without having to derate the ampacity of the wire. Whereas using EMT conduit, the wire needs to be derated having 4 or more current carrying conductors.
I have a total of 64 feet of the 4x4 wireways, but unfortunately, I don't have all the connectors to interconnect the wireways together nor do I have the end plates to enclose the wireway. I'll have to buy the connectors which sell for about $10 each.
For the end plates, I determined that a 4"x4" standard metal junction/gang box fits perfectly in the end of the wireway. I figured I can just drill a few holes and screw the metal junction box at the end of the wireway. The junction box already has punched hole tabs that can be removed to interconnect the ends of the wireway to EMT conduit.
Would using these standard 4"x4" metal junction boxes at the end of the wireways be code compliant? Although they're not made specifically for the purpose, they appear to fit perfectly and would work well for my use. Thanks for the help and any ideas or recommendations would be greatly appreciated.
