Vermont 15 Hour 2020 NEC for Master & Journeyman Electricians

A thorough grounding in the changes made during the 2017-2020 NEC code review cycle based on the documents submitted to the NFPA Technical Committees, the proceedings of the Committees, and industry expert analysis. The class includes the following:

Module 1: Intro & Chapter 1 – General (1-1/2 hours)

This module provides an overview and orientation as well as a look at the changes to definitions and general requirements for electrical installations. Eight new or revised definitions are covered, including “Equipotential Plane”, “Free Air”. “Island Mode”, and “Reconditioned” followed by changes to 110.12 Mechanical Execution of Work, 110.14 Terminal Connection Torque, 110.22 Identification of Disconnecting Means, and Spaces About Electrical Equipment. 

Module 2: Chapter 2 - Wiring and Protection (2-1/2 hours) 

This module covers changes to GFCI for Basements & Indoor Damp/Wet Locations, Changes to Lighting Loads Calculations, Surge Protection Devices in Dwelling Units, Maximum Disconnects in a Single Enclosure, and Emergency Disconnects at a Readily Accessible Location. Some of the most misunderstood and most often violated codes in the NEC are discussed, such as those regarding grounding and bonding. It also covers Overcurrent Protection, a new Article on Overvoltage Protection, Grounding Systems Permitted to Be Connected on the Supply Side of the Disconnect, GEC Connections to Rebar, Metal Enclosures to Connect Bonding Jumpers or EGCs, Restricted Use of Metal Frames as EGCs, and an Exception to Resizing ECGs. 

Module 3: Chapter 3 - Wiring Methods & Materials (1 hour)

This module presents significant changes, including the Reorganization of Article 310; Ampacity Tables; and a new Article 311 on Medium Voltage Cable, changes to Power Monitoring or Energy Management Equipment in Enclosures; Volume Allowance for EGCs and Equipment Bonding Jumpers; Outlet Boxes for Ceiling Fans; Measuring Type NM Cable from the Enclosure, Conductor Size and Termination in Cablebus; and Limitations of Single Conductor Applications in Cable Tray Systems. 

Module 4: Chapter 4 - Equipment for General Use (2 hours) 

This look at Chapter 4 begins with 10 changes, including a New Type of Fixture Wire - FFHH-2, Rating and Use of General-Use Snap Switches Dimmers and Control Switches, Electronic Control Switches, Installation Requirements of Controlled Receptacles, Tamper-Resistant Receptacles, and Single-Pole Separable Connectors. Later changes include new Panelboard Circuit Directory Locations, Methods of Grounding Luminaires; and Identification of Control GFCI for Appliances; Electronically Protected Motor Circuits and Controllers; Emergency Shutdown in One- and Two-Family Dwelling Units; Identification of Power Sources for Storage Batteries; and Retrofit Trip Units for Equipment Over 1000 Volts Nominal.

Module 5: Chapter 5 - Special Occupancies (2 hours)

This module presents 4 changes to the Articles on Hazardous (Classified) Locations, 4 changes to Article 517 on Health Care Facilities, and a wide variety of changes to Relocatable Structures, Agricultural Buildings, Manufactured Homes, Houseboats, and construction sites. The following exam questions cover material in this module: 

Module 6: Chapter 6 - Special Equipment (3-1/2 hours)

This module addresses changes to GFCI in elevators, signage for selective coordination, and Cables Under a Raised Floor of IT Equipment Rooms, along with a thoroughgoing restructuring of Article 625 on EVs, including new provisions for bidirectional power transfer systems. It also covers numerous changes to Article 680 Swimming Pools, and Fountains, including a return of rules on underground wiring that had been eliminated, revised codes on electrically powered pool lifts, and revised guidance on bonding and equipotential planes. The module finishes by looking at 15 changes to codes for Photovoltaic Systems. 

Module 7: Chapter 7 - Special Conditions; Chapter 8 - Communication Systems, Chapter 9 - Tables, and Informative Annexes (2-1/2 hours)

This module begins with changes to the Articles on Optional Standby Systems, Interconnected Electric Power Production Sources, Energy Storage Systems, and Critical Operations Power Systems (COPS), including guidance on incorporating alternative power sources, a complete overhaul of Article 705, and a revision of Transfer Switch rules for COPS. Changes to Articles 710 on Stand-Alone Systems and DC Microgrids, clarifications on the Use of Class 1, Class 2, and Class 3 Remote-Control Signaling and Power-Limited Circuits, and three changes to Article 770 on OFC complete the look at Chapter 7.

The course finishes with a survey of the reorganization of Article 800 and the new Article 805 that profoundly changes how communication systems are covered by the NEC, followed by changes to Article 840 on increasingly important Premises-Powered Broadband Communications Systems, a single change to the Tables of Chapter 9, and the more user friendly changes to Annex A that catalogs Product Safety Standards.
