Course No.: ED102
CEUs .08

Event Navigation

Synopsis: When it comes to designing an electric power system, the NEC® is just the minimum. This is the second part of a 2 day program to show you how to design and electrical system using the NEC but also how to go beyond the code. When and why do you need to oversize neutrals? How do you perform lighting calculations? Learn some of the “tricks of the trade” when it comes to electrical design. This class is also part of the one week Power System Engineering course held publicly several times a year.
