I work in a ship yard and we're currently looking into fabricating a portable power outlet unit.
Supply: 208VAC 3PH, 100A
Feed: 110VAC, 1PH, Various 30A and 60A
The vendor we typically buy them from has a long lead time that isn't acceptable. We have the tools and resources to build the portable power outlet unit in house.
Does fabricating our own panel violate code? I'm not sure if UL approval or UL508a certification is required. Can someone please clarify? My thoughts are that we could build a unit that is up to code standards, but does building the unit violate code in and of itself?
