Get on track with the NEC video training series from the Code source!
NFPA's 5-part NEC Expert video training course demonstrates and explains NEC requirements, covering critical topics for electrical contractors, installers, designers, and inspectors.
Now available in VHS or DVD and updated for the 2005 Code, NEC Expert uses field examples, graphics, and computer animations to let you see requirements applied. Programs cover:
* Grounded Systems and Article 250, with clear explanations of circuit and system grounding connections. Examine grounding electrode systems (reorganized section 250.50 Part III), service equipment bonding, proper use of GFCI, and AFCI (new Section 210.12).
* Overcurrent Protection of Conductors, including updates in Section 240.86 to permit series-rated systems for existing installations to be selected by licensed professional engineers. View demonstrations of how to work with fuses and circuit breakers, find allowable ampacities and temperature ratings of conductors, and determine where overcurrent devices are located in circuits.
* Installing Services, including overhead and underground services, service entrance conductors, service equipment, and services rated at over 600 volts. Learn about new applications of cable trays for service conductors in revised Section 230.44.
* Installation of Motors and Transformers. Progress from basic concepts to complex installations. View examples of calcs for transformer overcurrent protection. Introduces new installation requirements for adjustable-speed drive installations.
* Remote Control and Signaling Circuits in Article 725, including new provisions for circuit integrity cable, which improves survivability of critical systems.
