Exam 9: Conductor Types and Sizes

For pure metals such as silver, copper and aluminum, the resistance of a conductor ____ as the temperature increases.

The ____ of a conductor is limited by the temperature that its insulation can tolerate without deteriorating and/or losing its insulating quality.

____ is the voltage drop caused by current flowing though the resistance of the wires.

Which is the smallest AWG wire size?

The amount of heat generated by current flowing through a conductor depends on the current value and the conductor's ____.

A feeder circuit consists of the conductors between the service equipment and the final branch-circuit overcurrent device.

Flexible cords and cables may be used for the fixed wiring of a building.

What unit is used to measure rectangular conductors?

A correction factor is used for the ampacity of conductors in installations where the operating temperature is above ____ degrees Fahrenheit.

What is the most common insulating material used for conductors?

In the splicing process, when using a knife for stripping wire insulation, the insulation should be cut at a right angle to the conductor.

To convert circular mils to circular millimeters, divide circular mils by ____.

Line loss is power dissipated as heat.

For which temperature is resistivity (K) defined?

The resistance of a wire is inversely proportional to its length.
