In the case of severe acute aortic insufficiency, all individuals should undergo surgery, if there are no absolute contraindications (for surgery). Individuals with bacteremia with aortic valve endocarditis should not wait for treatment with antibiotics to take effect, given the high mortality associated with the acute AI.
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.
Locate line posts 15 to 20 feet apart. Use the 15-foot spacing for steel posts or wooden posts with less than 3-1/2-inch diameter tops. Posts may be driven or set with either power or hand tools. If you have more than a few hundred feet of fence to build, use a power driver or auger.hen a fence is more than 650 feet between corner posts, put braced-line post assemblies every 650 feet in the fence line. A braced line assembly is the same as a single-span braced corner except that a second diagonal brace wire is used to take fence pull in the opposite direction.
