EWRB EXAM 49 QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS GRADED A++ State the main reason why a large industrial electrical installation has a higher prospective short circuit current (PSSC) than a domestic electrical installation. The fault loop impedance is lower Because the distribution transformer is close to the installation or on-site A CT metering circuit is measuring the consumption of an industrial electrical installation at near to full load. The CT secondary must be shortcircu...

accessible, readily (readily accessible) correct answers capable of being reached quickly for operation, renewal, or inspections without requiring a person to climb over or remove obstacles or to use portable ladders. bonding correct answers connected to establish electrical continuity and conductivity: the purpose of bonding is to establish an effective path for fault current that facilitates the operation of the overcurrent protective device bonding jumper correct answers a conductor use...
