Cables and Conductors 1 - DVD

$ 195.00

Summary

This 58-minute DVD is a basic introduction to low-voltage conductors and cables. It explains how conductors are constructed, how they are classified, and how to select the right conductor for each job. It also demonstrates how splices and terminations are made, and how to pull conductors through conduit.

Note: The procedures shown here are for low-voltage conductors (under 600 volts). Applications in substations include relay control circuits, drive motor circuits, and 120-volt outlets.

Training Sessions

How a Conductor is Constructed – 6 minutes
Defines the differences between “conductor” and “cable.” Explains that conductors can be bare or insulated, solid or stranded, jacketed, and sheathed.

Classifications and Ratings – 11 minutes
Describes the standards used to measure wire sizes. Explains how to select a conductor with the appropriate insulation rating, voltage rating.

Selecting a Conductor – 13 minutes
Demonstrates the procedure for selecting the right conductor for the job, using data in an ampacity table and an insulation table.

Splices – 12 minutes
Demonstrates how conductors are spliced using wire nuts, sleeves, split-bolts, and lugs.

Installation – 11 minutes
Explains how to select the correct conductor for a job, also considering surge (motor-starting current), voltage drop over the length of the wire, and available conduit size. Demonstrates how to install conductors in a conduit, from a control box to a motor.

Terminations – 5 minutes
Describes popular wire terminations. Demonstrates how to attach them to conductors and apply insulating tape.
