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.
Use a little league field with a 60 foot length base path as an example. The homerun fence is 200 feet away from home plate. Home plate usually is at least 15 feet away from the backstop fence behind the plate. So, the distance from the backstop to the homerun fence is about 215 feet.The area of the ball park is one fourth the area of a circle with a radius of 215. Area of a circle is pie X radius squared. So, you have A = 215 * 215 * 3.14. This is about 145,000 square feet.o, the distance from the backstop to the homerun fence is about 215 feet.
