All rights reservedDisclaimer | Although the grounding electrode system (GES) is connected to the equipment grounding system at the service panel, the GES has virtually nothing to do with reducing hazards from problems in the wiring inside the house. 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. Using conductors having coated strands, different stranding type, and, especially, other temperatures changes the resistance. Keep in mind that the area of the wires must be less than 40% of the internal space of the pipe when 3 or more wires are present. The term ground wire, for example, may refer to one of three different things: In the service panel, the ground wires attach to a neutral/ground bus bar, which is bonded to the metal panel housing via a main bonding jumper. Carefully fix the ground wire until it reaches the ground rod located outside the house. Add To Cart. Offer excludes localized promotions. By bonding conductors or potential conductors, the system provides a low-impedance path for fault currents. However, we recommend 2 or 2.5 inches if running three wires in the same conduit.
