2 26835What size cable (based on voltage drop) is required to supply a 40 A three phase boiler if the wiring system is 75V single insulated cables installed in non-metallic rigid conduit 56m from the main switchboard? Voltage drop in the consumer's mains is 8V.
1976Determine the minimum cable size for a 28A single phase final sub circuit originating from the distribution board supplied by three phase submain. The route length of the final sub circuit is 54 m. Assume 1% voltage drop in the consumer's mains. Submain specification: Cable: 50mm2 4 core V75 copper; Route length 42m; Maximum demand 135A per phase
