Home / Neutral wire and grounding of distribution box casing
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. 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. Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. The specific neutral grounding method chosen by the utility can have significant impacts on reliability of service, safety, protection coordination, power.
Power transmission and distribution systems are earthed for electric shock and fault protection. This chapter presents the principles and practices of grounding for power systems. An earthed power
