Looking for an answer if anyone has seen this concept present local code issues.
I am in the process of constructing a 4-wire, 240V relocatable power tap (i.e., multiple port outlet "strip.") on a 30A circuit. A NEMA-4 enclosure forms the "strip" distribution. Four 10/4 cables are connected to the enclosure through Heyco PVC compression connectors. Wiring is all stranded, portable 10/4 cabling. Jumbo wire nuts will join four #10 wires together inside the NEMA box. According to the Thomas and Betts datasheet, these wire nuts are meant for the wire gauge and number of wires.
Two 30A ceramic-type fuse cartridges will be installed to fuse both line side wires. On one side of the NEMA box are three 2-ft serving cables, each terminated in an L14-30R Twist-Lock receptacles. On the other side of the NEMA box is a L14-30P Twist-Lok pug used to plug this assembly in to the 30A wall circuit. In an nutshell, one 10/4 cable from the box goes into the wall, then gets split three ways to separate pig-tail receptacles with the input side being double-fused.
Since this is not a premise wring issue, NEC should not be involved. Otherwise, I would have posted in the NEC forum. From a local products code perspective, is this practice generally accepted?
