The Motor Overload Protection & Voltage drop A machine that process chemical materials has an electric motor C, a group of heating elements. The feeder to the motor comes from a distribution center 200 ft away. from the motor when there is a 208V, 3?, 60Hz power supply. The motor is a 3? Class A induction motor rated @ 2.5hp, 208V, 60Hz. There are 3 heaters rated @ 7.5kw @ 120V. Determine: a) total power supplied to the machine b) the wire size to be used in the feeder (PEC) c) Overload protection

Electrical Power: The power rating $P,$ in watts, of an electrical appliance is determined by $$ P=I \cdot V $$ where $I$ is the current, in amperes, and $V$ is the voltage, measured in volts. If the appliances in a kitchen require 30 amps of current and the voltage in the house is 115 volts, what is the wattage of the kitchen?
