The ground wire is intended to be a low-impedance path to ground, to safely carry the current of a ground fault until the circuit breaker trips. Applications and Design Manufacturing Processes All the metal parts that are not designed to carry any current, such as internal combustion engines, the fuel tank, and the generator housing, are bonded to the metal frame. If you encounter hard ground, you can wet it down a bit to loosen the soil, and you can drive the rod at a bit of an angle to make it easier in rocky terrain. One such major condition is when the portable generator feeds power to the home, office, trailer, shop, etc., through a transfer switch. A wire runs from this bar to a long copper rod which is physically pounded into the dirt (aka 'ground'). Using conductors having coated strands, different stranding type, and, especially, other temperatures changes the resistance. Grounding means electrically wiring parts of the solar system to the earth (earthling). The voltage drop and length of the wiring determine which wire is used. Long runs require a thicker gauge wire.
