How to connect the grounding electrode of the construction site electrical distribution box
Wire-type GECs that have to be spliced must use either a compression-type irreversible connector listed for grounding and bonding or be joined using an exothermic welding. Similarly, because metal water pipes. Grounding electrode conductor (GEC): The wire that connects the main panel to the grounding electrode (usually a rod). Ground bar in the panel: The terminal where all ground wires are connected. Failure to install these connections properly can result in shock, fire, or, most certainly, power quality problems. Let's take a look at each one in more detail. 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.
