Get a close-up view of Overcurrent Protection of Conductors!

Unit Two in NFPA's updated NEC Expert video training series provides thorough instruction on overcurrent protection, directly from the leaders in electrical safety.

This self-contained program concentrates on Article 240, including updates in Section 240.86 to permit series-rated systems for existing installations. The program addresses critical areas and briefs electrical workers on:

• Selection of overcurrent devices and their documentation and stamping by professional engineers
• How the series combination devices must be field marked on end use equipment, including identification of the upstream overcurrent protective device
• Fuses and circuit breakers and their standard ratings
• Allowable ampacities and temperature ratings of conductors

Train employees in your own time frame, and replay complex segments as often as needed with NEC Expert! An index card lists specific code sections and pinpoints where they are covered on the video. (Approx. 45 min., 2005)
