Title: Lesson
Course: Industrial Wiring (IC 104-IC 104) > Section: Web Content

The first key point in chapter one is on the ground field testing, as the test should be done annually, you should get familiar with the different types of testing methods. You will also be getting use to the box trade size chart and the amount of conductors that can be installed. Get familiar with different methods of burying cable, but don't spend a lot of time with there specific site plans. In chapter 6, with the ampacity and insulation type you will be able to determine the conductor size, be able to make corrections for adjustment factors, and to correctly install parallel conductors. Knowing how to use an ohmmeter and a Megger to test insulation is also very important.
Reading Assignment:
Electrical Wiring Industrial - Chapter #1; Plans and Sitework
Electrical Wiring Industria l- Chapter 6; Using Wire Tables and Determining Conductor Sizes
Power points are available in the Handout section.
Videos are available below for further explanation of material content.
In the Coursework section there is a worksheet related to the conductors and box fill. There is also a drawing worksheet that will have you wire different circuits and determine box fill from the wiring. One of the videos below is dedicated to explaining how to complete those types of worksheets.
The Forum section this week will have a topic directed toward continuous load and be sure to share any questions on other topics as well.
When taking the test "Be SURE to use the NEC table for RACEWAY, CABLE, or EARTH (Directly Buried) to find ampacity.
