Students identify different insulating materials and how circuit voltage, temperature and use/situation have an effect on the ampacity.

6.2 To identify uses for different conductor types. (COM)

Look at the uses for cables, cords and printed circuit boards.

6.3 To determine the American Wire Gauge (AWG) number of a conductor. (NUM)

Demonstrate how to use a wire gauge to determine different wire sizes.

Have students convert rectangular or square dimensional conductors to equivalent circular mil area measured in square millimeters.

Students should calculate:

• differences between circular mils, square mils and square millimeters
• line losses and line voltage drops
• allowable conductor sizes and ampacities.

As bonding refers to a method of fusing different conductors together students should:

• identify bonding requirements
• identify common bonding methods
• determine common conductor sizes.

6.5 To be able to terminate conductors.

Students can prepare different types of conductors for termination, using solderless connectors, screw and lug connectors, and solder connections (see Module 22).

Have the students build extension cords using attachment caps and cord connectors.
