WebSep 27, 2024 · Grounding is the very foundation of a building or structure’s electrical system. According to 250.20 (B) of the 2024 NEC alternating-current (AC) systems of 50 volts to 1000 volts must be grounded which means referenced to earth. This is accomplished through a properly installed grounding electrode system. WebTypically, residential GECs are size 6 American wire gauge (6AWG) copper. Ground rods are typically 1⁄2-in. or 5⁄8-in. copper-clad steel rods at least 8 ft. long. The Ufer or concrete-encased electrode is the preferred grounding electrode and must be used if new concrete footings are poured.

WebBare or green = GROUND: In the event of a ground fault, the ground wire provides a low-resistance and effective path for the fault current to return to the electrical panel. This trips the circuit breaker or blows the fuse, cutting off the flow of electricity to help prevent electrical shock or fire hazards. WebIt is actually connected to ground only in specific places, typically the electrical panel. This way it shares the same voltage as the earth ground it is connected to and can be treated as "ground" while separating intended current from fault current.
