Mastering the NEC 2005 will prepare you for on-the-job and the exam!

Product Details :

There's no way you can memorize everything in the National Electrical Code. But if you understand why and what is intended, you will be better prepared to remember the details you need for every day use.

Mastering the NEC DVDs are designed to help electricians, designers, supervisors, contractors and maintainers understand the NEC. The DVDs can be used to train and re-train electrical staff.

The twelve DVDs are packed with updated information that affect your daily work.
