Sorry Guys and Gals, but I'm not that hip when it come to farming. A friend of mine has asked me to wire his horse barn. So the first thing I read was Art. 547. It was not that difficult to understand. I understand that I have to install a ground plane and a voltage gradient. But everywhere I research the issue it refurs to cows. Does it also apply to horses? My friend only has 2 horses and a tack area. I plan on running a 60 amp service, 4 wire with an insulated ground, 2 ground rods at the barn, all GFCI protection for recepticles, fixtures that are dust-tite, no electrical in the stables, NMC and PVC for protection, and the ground plane with a voltage gradient consisting of 4 ground rods driven at a 45 deg angle away from the structure no less than 12" apart at the enterance.
Thanks a Blessings
