Standard for grounding wires in primary distribution boxes
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. Grounding is necessary to assure correct operation of electrical devices, to assure safety. The primary function of the Equipment Grounding Conductor (EGC) is to establish a safe, low-impedance path for fault current to return to the source. This conductor is an integral part of the circuit's fault protection system. SEC Distribution System extends from the MV (33 kV, 13. 8 kV) feeder outlets of HV / MV Substations down to SEC Customer interface including KWH-Meters and meter boxes. Whether you're a seasoned pro or just starting out, this comprehensive guide will give you practical. IPMENT, STRUCTURES, ETC.
