This 4-hour program is presented in 4 lessons. Each lesson has a test which must be passed with a minimum score of 70% and a survey which must be completed before proceeding to the next lesson. The lessons are listed below:
2017 NEC Changes: Overcurrent Protection and Grounding & Bonding (RV-11107)
2017 NEC Changes: Enclosures and Boxes (RV-11108)
2017 NEC Changes: Hazardous Locations (RV-11112)
2017 NEC Changes: Special Occupancies (RV-11113)
Lesson 1: The first lesson covers Article 240 and 250 of the National Electrical Code (NEC) and the requirements for overcurrent protection and for grounding and bonding. Changes include the addition of arc energy reduction requirements for fuses, additional options for the grounding of separately derived systems, changes to the allowed and prohibited types of grounding electrodes, recognizing new options for intersystem bonding, clarifying the rules for parallel conductors, and others.
Lesson 2: Chapter 3 of the NEC contains requirements for wiring methods, enclosures and boxes. Notable changes that include the addition of a new column in Table 312.6(A), new box fill requirements for barriers in boxes, clarifying the rules for cables entering enclosures, and new rules for separable attachment fittings.
Lesson 3: Chapter 5 of the 2017 National Electrical Code (NEC) also contains requirements for special occupancies. Notable changes include the relocation of fourteen definitions to Article 100, a surprising new allowance for wiring methods in Class I locations, underground wiring changes for commercial garages and fuel dispensing locations, and new fuel storage classification requirements
