Mastering the NEC 2008, 12 Volume DVD Set

Mastering the NEC 2008 prepares you for on-the-job and your exam.

There's no way you can memorize everything in the 2008 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.
