Mike Holt Enterprises

Mike earned a masters degree in the Business Administration Program (MBA) from the University of Miami. He earned his reputation as a National Electrical Code (NEC) expert by working his way up through the electrical trade. Formally a construction editor for two different trade publications, Mike started his career as an apprentice electrician and eventually became a master electrician, an electrical inspector, a contractor, and an educator. Since 1975, he has provided custom in-house seminars for groups such as IAEI, NECA, ICBO, IBM, AT&T, Motorola, and the U.S. Navy. Mike has taught more than 1,000 classes on 30 different electrical-related subjects — ranging from alarm installations to exam preparation and voltage drop calculations. He continues to develop seminars, videos, books, and software as well as contributing monthly Code content to EC&M magazine.
