Familiarity with the NEC is vital for every HVAC Contractor/Mechanic. There are many ways to approach continuing education on this vital codebook. This class will focus on the changes made to the 2017 NEC that most significantly affect the HVAC trade. By addressing the changes to the 2017 NEC that have the greatest impact on HVAC, the goal is to enhance understanding of the entire NEC as well as to ensure that you’ll be able to comply with all current electrical codes and regulations. In order to give you as clear a view of each changes as possible, each will be presented first with a “thumbnail” overview, then the 2017 National Electrical Code language is shown with any deletions struck through and a clearly delineated 'cut and paste” overlay of any new language that has been added, followed by a discussion of what the change means and the reason it was installed in the Code. The goal is to express every change in clear language, to focus on how the changes should be applied by a working HVAC mechanic, and to provide the resources to explore the change more fully for those who wish to do so.
The class includes a review of how the NEC is organized and instruction on how it’s applied as well as a review of a few key changes to Chapter 3 - Wiring Methods and Materials. The bulk of the class looks at the Chapter most essential to HVAC (Chapter 4 – Equipment for General Use), containing some of the most rapidly updated provisions of the NEC regarding safe and reliable installation of equipment for general use. By the end of this class, students will be able to navigate the 2017 NEC far more effectively, locate and act on the broad changes to and the new Articles in the NEC, more effectively use raceways, boxes and enclosures, and calculate space and sizing in order to abide by the latest NEC rules, apply the safest and most reliable methods for cables entering enclosures, cables on rooftops, and for trimming and installing LFMC and EMT, apply the latest definitions and guidance on appliances and on fixed space-heating equipment, access a new and very detailed Article on Fixed Resistance and Electrode Industrial Process Heating Equipment, and stay current on codes on flexible appliance cords, connections to motors, air conditioning, and generators.
