I'm excited when I get a new Code book and start customizing it for my personal use. The first step is to place the cool Mike Holt NEC Tabs, following the instructions (begin at the back of the book)! The next step is to highlight any rule I review and underline important words. The NEC is intimidating, but if you get a Code book and you highlight it and underline the words as you watch my videos, post, and questions. You'll be surprised how you start feeling a little more comfortable with its u

Article 250 of the NEC is perhaps the most misapplied, misinterpreted, and violated article in the Code. The terminology used in this article has been a source of much confusion. “Bonding jumper, main bonding jumper, system bonding jumper, supply-side bonding jumper.” What are these? How do they differ? How are they sized? Watch this video clip to get the answers. https://www.mikeholt.com/newsletters.php?action=display&letterID=2253 | Mike Holt Enterprises

The first time you’re called upon to size a conductor and overcurrent device for central air-conditioning and you look at the nameplate requirements that clearly state that a 10 AWG copper conductor and a 50A OCPD are required, it may contradict everything you’ve learned about small conductors. In fact, you may adamantly insist that 6 AWG is required by the Code and you’d be wrong! Learn why in this video on section 440.4(B) of the NEC... https://www.mikeholt.com/newsletters.php?action=display&l

When burying wiring we need to have sufficient ‘cover’ in accordance with NEC Table 300.5(A). In this case it’s at least 20 inches, not 18! | Mike Holt Enterprises
