SCROLLING THROUGH QUEStion-and-answer Internet forums for electricians, plant operators, and contractors reveals that a frequent topic for discussion is voltage drop-the difference between what an electric power system makes available and what actually appears at a downstream load.
What's the lowest load voltage allowed by Code? How large a conductor is needed? What are the rules for paralleling conductors, or connecting different size conductors in series? And just how does reduced terminal voltage affect the connected load?
The answers to such questions, as posted on the Web sites, often reflect a good understanding of the National Electrical Code, but also indicate much ...
