In the case of severe acute aortic insufficiency, all individuals should undergo surgery, if there are no absolute contraindications (for surgery).

Where the ground rod is located far from the main electrical panel, thicker No. 3 wire may be required. In areas where codes require two ground rods because of high electrical resistance in the soil, the rods must be spaced at least 6 feet apart and interconnected by a buried jumper wire.
An alternative is to set posts 30 feet apart and place two stay rods in the wire between each set of posts. Cost would be reduced about $85 for every 1,320 feet of fence, or $0.064 per foot.
