Webinar two will discuss the revised and restructured requirements for the machine supply circuit and disconnecting means per chapter five.

Thursday, October 22 at 1:00pm CST

Learning objectives:

  • The definition of machine supply circuit
  • Separation and termination of conductor
  • Back-fed terminations
  • Wire bending space

Webinar three will cover the revised requirements for protection from electrical hazards found in chapter six of NFPA 79.

Thursday, November 5 at 1:00 p.m. CST

Learning objectives:

  • Restricting access to enclosures
  • Evaluating unrated enclosures for protection
  • Accessing an enclosure containing live parts
  • When the use of a key or tool is necessary for access
  • When a disconnecting means is not required
