Ok I have a home owner that did his own work and now wants me to fix the mess. There was a barn but it burned down (imagine that). He saved the two underground feeds, and built a new metal building that's used to store farm equipment and now he wants me to dig up the feeds inside the new building and feed lighting and receptacles. Knowing that I cannot run two feeds, is it acceptable for me to utilize the black conductor from one feed to make a three wire feed out of this conundrum, tagging it with red tape and terminating at main panel using double pole 30-amp breaker? As both are run in seperate parallel raceways underground using 10-2 UF cable in EMT I would ensure both have ground conductors terminated at EGC and I plan to install a disconnect and a 6 six space loadcenter in the new detatched structure. I also plan to sink two 8' x 5/8" grounding electrodes spaced 6 feet apart by this structure tied with #6 and terminated at EGC. No livestock issues so I dont see any need to run a bunch of GEC in the slab to equalize it with any transient neutral voltages. All receptacles installed in detatched structure will be GFCI protected.
Anyone see problems with my logic? Any requirement for arc fault protection on this feed?
