How to handle the grounding of a secondary distribution box

Connecting the receptacle grounding terminal to the metal box ensures an effective ground-fault current path. The basic rule achieves this through an equipment grounding jumper; four exceptions allow other methods. A sub panel is a secondary distribution point that receives power from the main se...
