How to connect the grounding electrode of the construction site electrical distribution box
Grounding electrode conductor (GEC) – wire connecting the panel to the ground rod. Drive a ground rod into the earth near the panel. Connect the GEC. The National Electrical Code (NEC) lists eight specific methods to make grounding and bonding connections in Sec. Failure to install these connections properly can result in shock, fire, or, most certainly, power quality problems. The primary purposes of grounding are to stabilize the system's voltage during normal operation and to provide a path for high-voltage events like lightning strikes or line surges to be. The grounding electrode system is the direct connection to the earth, designed to dissipate lightning energy and stabilize system voltage.
