LIGHTNING PROTECTION AND GROUNDING
If additional grounding is needed and this is a terminal pole, a #2 bare copper counterpoise wire 100''-150'' long may be placed in the conduit trench and connected to the ground lead.
How many grounding electrodes are needed for a distribution box
The NEC requires a minimum of two grounding electrodes, unless one electrode has a resistance to earth less than 25 ohms. The Grounding Electrode Conductor is the critical link connecting the grounded conductor at the service, the main bonding jumper (MBJ), the equipment grounding conductor (EGC) bus, and the Grounding Electrode System (GES). This metallic component provides a direct, low-resistance path for unwanted electrical energy to dissipate safely into the earth. The. Today, we're diving deep into the world of distribution box grounding, breaking down the standards, and shining a light on those sneaky mistakes that even experienced electricians sometimes make. 24 (A) (1) through (4): ...
