Grounding of the secondary distribution box door
Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). The ground resistance between all system parts shall be <. Then your supervisor walks by and points at the ungrounded door— "Add a wire to that!" Ugh. Here's why it matters: Static discharge: Metal doors can build up static charge, especially in high-voltage environments. Fault. Power from factory ground must be installed by a qualified electrician. Each DISTRIBUTION BOX and controller must be grounded. Grounding of the units: Attach a ground wire from one of. Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. Equipment Protection: Grounding protects substation. The primary function of a grounding grid is to protect people and non-current carrying metallic objects, such as poles, towers, equipment enclosures, and switch handles, by keeping the ground potential as close to zero as possible during fault conditions. Fault Scenarios (Like a Lightning or LTG.
