Stop in for a cup of coffee

We also used ground rods on all of our containers at the farm. Each farm had one, they worked great for storage office space and break rooms. By same token we converted school buses into rolling lunch rooms complete with generator and porta pot. We did have considerable trouble with meth heads stealing out of them when parked.
A few years ago, we had a utility pole rot out from termites. On my place there is a pole that carries 12k and 220 on it. Both are non insulated. Well, the 12 k got into the 220 to the house, it melted off the ground rods, three, copper, and the ground to the water pipe. Melted off the pipe!! BUT no damage inside except one thing. A paper shredder. SDGE replaced that... Good grounds a must...
