1) A three-phase machine compose of the following items. Design the panelboard for this machine (cable and circuit breaker)
1.1) A 5-hp three-phase induction motor
1.2) A single-phase controller box comsuming 300 VA
1.3) A single-phase heater of 1500 VA
2) The front entrance of the factory is 1000m away from the distribution box. The entrance compose of three 40W fluorescent lamps, two 100W spotlight and 2 outlets. The cable from the distribution box to the main entrance is 16 sq mm. If we want to add an air condition ( inverter), what is the maximum size of the air condition? Allow the voltage drop of 10%
