| Learning Objectives |
|
Upon completion of this course, the participant
should be able to:
- Apply the working and dedicated space requirements of the code given various
industrial case studies.
- Size the ungrounded, grounded, and grounding conductors and the overcurrent
protection devices for various industrial applications including: heaters, motors, and variable frequency drives.
- Correctly size various types of raceways and enclosures given such variables
as conductor insulation type, number of conductors, size of conductors, type of load, distance between overcurrent device
and utilization equipment, and temperature.
- Apply the code to determine the installation requirements for various types
of raceways and enclosures to include cable trays, rigid metal and nonmetallic conduct, liquidtight flexible metal and nonmetallic
conduit, motor control centers, switchboards and panelboards
- Select and apply the proper equipment to be used in typical industrial hazardous
locations.
