Before my shop floor was poured I drove a 1/2" 6' copper rod 5 1/2 ' into the ground below where the 100 watt service was going to be located. ...( 10' ceiling why would I not figure I needed a 10' ladder

)
Requirements differ in places When I built my shop 250' from the house with underground wiring (#1 copper in conduit for overkill) to a 100 amp sub panel it was recommended by friends at the utility company to put in
three ground rods about 6' apart, the first connected directly to the box and the others jumpered.
It was also recommended) to jumper the ground to rebar and bring it out to a jumper to the other ground rods. Apparently 1400+ sq ft of rebar in concrete can make a significant ground.
Many are concerned about the cost of big copper wire but I think it's insignificant compared the overall cost of the building materials. The oversized wire gives me less than 1% voltage drop even when two big motors cut on at the same time. I have a bunch of 50amp receptacles inside and outside the shop for welders, plasma cutter, etc.
All utilities on our farm are underground, even the 800' water and 1200' power lines I ran down the horse pasture and then to the security gate. #2 copper in conduit to an 80amp box for this run.
With the property designated as agriculture use in this county there are no permits required for any construction that can be related to agriculture and no one inspects. I grow, use, and sell wood products, hatch and raise game birds, do animal care and surgery as needed, and maintain farm equipment. I was told this property qualifies. However, I do follow all codes.
Another thing many but not everyone around here knows is if you have at least 15 acres (we have 27) with some of it forested a landowner might qualify for a
Forestry Greenbelt program. A forester comes out and walks the property, makes a map showing different zones and their history (trees on previous fields, old growth, etc), makes recommendations and approves the Greenbelt application. This immediately cuts property taxes to about 1/2.
A couple of years later I asked to forester to come back and give feedback on my progress. He was surprised - he said almost everyone gets on the Greenbelt program for the tax reduction and almost no one does anything afterward. He said I was one of the very few who was actually following his recommendations! (We stood out in the rain talking for a couple of hours - what a great and knowledgeable guy!
I can't imagine how many tons I've removed of Ailanthus altissima (tree of heaven), bush honeysuckle, privet, choking poison ivy, wild grape vines, and the worst invasives ever introduced by people with defective brains: bittersweet. My goal is also to take down every pine tree on the property and let the hardwoods grow. The place sure looks better for it. Helps to have big equipment. Working on cleaning up another acre in my spare time.
Hey, I've found poison ivy vines over 4" in diameter! Big enough to put pieces on the lathe. (I was told the wood from poison ivy was sometimes used to make mother-in-law spoons. Wonder what that means...)
