The dwelling has a floor area of 142 sq. m. It has a typical household appliance including one 8 kW electric range, one 1 Hp room air-conditioning unit, one 3 Hp room air-conditioning unit and one 1 Hp water pump. (Draw the diagram) Determine the following: Total Load:A) Service Entrance ConductorsB) Service EquipmentC) Other Load
Determine the size of the service-entrance conductors required for twenty (20) 900 sq.ft units in a multi-family dwelling. The units have the following loads: Ø General lighting and receptacle loads. Ø Two small kitchen appliance loads and one laundry load per unit. Ø Special appliance loads. Each unit has: 10-kVA space heating unit; 12-kVA range; 5-kVA water heater; 1.2-kVA dishwasher; and 1-kVA disposal. Use both the standard and the optional methods to determine the service-entrance conductor size for the phases. Assume 240-volt service.

Question 2(a) a) Mr. jojo, lives in a four flat house, the conditions of the lighting system was very bad and he needs help. He wants the design to be as follows, a combinational circuit that controls the ceiling lights in my downstairs hallway, which has three wall switches: one at the front door (A), one at the back door (B) and one in the family room (C). When I walk in the front door, the ceiling lights are off, the A switch is ON and both the B and C switches are OFF, From these initial conditions, changing the position of any switch should turn the lights on; changing the position of any switch (again) should turn the lights off. (b) The Karnaugh map method is very commonly used for the simplification of Boolean expressions, since no algebraic rules are applied in this method. It is simply a graphic method and provides systematic approach for getting the simplified Boolean expression. Kindly Minimize the logic function Y (A, B, C, D) = Σm (0 1, 2, 3, 5 7, 8, 9, 11, 14).
