Earthing guide for surge protection
As we have seen earlier, lightning discharges to ground set up large transient voltages, with respect to local ground, on incoming cables. So far, in dealing with surge protection, we have assumed a
Repeated grounding at the incoming terminal of the 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. Grounding electrode conductors must be connected at. The service neutral conductor provides the effective ground-fault current path to the source to remove dangerous voltage from a ground fault by opening the circuit overcurrent protective device (OCPD) [250. Most North American distribution systems have a neutral that acts as a return conductor and as an equipment. Navigating the grounding and bonding of electrical systems can be a tall task unless you have taken the time to fami...
