A DC motor that draws 7.2A is located 85 feet from its 240VDC source. The copper conductors supplying the motor operate at 68°F. Voltage drop on the conductors must be limited to 2% for the motor to properly operate. What size, in circular mils, copper conductors are required for this installation?

match column a to b. Electricity flows from the power plant Through wires to the step-up transformer. The transformer raises the voltage so it can travel long distances - it is raised as high as 756,000 volts. Electricity is generated in the power plant by hydroelectric, nuclear, wind or geothermal energy. The electric current then runs through the power lines to the substation transformer where voltage is lowered to between 2000 and 13000 volts. The turbine spins a huge magnet inside a copper wire. Heat energy converts to mechanical energy which then converts to electrical energy in the generator. From there, electricity comes into your home through a service box, where your heter IS located to electrical consumption. measure your Wires Taice electricity around your home, powering your lights and all your other electrical appliances. Electricity is then taken through the lines to a pole transformer or transformer box if underground then the voltage is lowered again to 120 or 220…
