Uncovering the Cost Benefits of a Good Lighting Circuit Design

EC&M, Apr. 2015, by Aaron Hesse. (Free registration required to view full-text)

"Iterative voltage drop calculations are some of the most tedious and time-consuming components of an electrical design process. This is especially true for large lighting installations, such as those found in parks and parking lots as well as roads and highways. As a result, it is common for designers to oversimplify voltage drop calculations in a lighting design. With the lighting industry trending toward LED use, it is becoming increasingly common to string large quantities of luminaires on a single circuit due to the decreased load per luminaire. Now more than ever, detailed voltage drop calculations can avoid over engineering of lighting systems and substantially decrease project costs."
