Hopefully everyone has a fantastic holiday season! The weeks leading up to Christmas can be frantic with decorating, crowded malls, finding the perfect gifts, wrapping, and visiting family. As enjoyable as Christmas day is, it seems to come and go entirely too quickly.
One of my favorite parts of the build up to Christmas is seeing homes decorated with Christmas lights. Whether your house looks like the Griswold household or you took a milder approach to decorating, all Christmas lights have something in common. Christmas lights are considered festoon lighting.
According to the Article 100 of the NEC, festoon lighting is defined as a string of outdoor lights that is suspended between two points. Festoon lighting is mentioned in Article 225 Section 6(B) in regards to conductor size and support, but for this blog we’ll highlight Article 590 Section 3(B). Article 590.3(B) states temporary electric power and lighting installations shall be permitted for a period not to exceed 90 days for holiday decorative lighting and similar purposes.
In other words once Christmas passes and the fast pace starts to return to normal, it’s okay to enjoy your Christmas lights for a little longer. Just remember to remove your festoon lighting within 90 days of installation.

“Preferred Parking” was featured in the December issue of Modern Steel Construction.
MORGANTOWN, West Virginia, excels at natural beauty and football, among other things.
Home to West Virginia University and its acclaimed Mountaineer football team, the town of roughly 30,000 (twice that when WVU classes are in session) sits amongst the rolling hills of northern West Virginia along the banks of the Monongahela River.
But one thing the town lacks is public parking, particularly in the downtown area. (more…)
“I used to believe that good engineers never made mistakes.”
This story was featured in the December 2016 issue of Modern Steel Construction.
I used to believe that good engineers never made mistakes. Now I believe that good engineers have simply learned to never repeat mistakes. In the decade I’ve been working as an engineer, I’ve made countless decisions — most good, but some bad. Each decision taught me something, but the lessons from the bad ones are harder to forget. One of those lessons has stuck with me since my first week on the job, more than ten years ago.(more…)
LED light fixtures are becoming the industry standard and will likely replace fluorescent lighting.

Have you walked outside recently and felt sticky as sweat starts to bead up on your forehead? In the summer, the relativehumidity can seem unbearable. The HVAC field involves more than the acronym H (heating), V (ventilation) and AC (air conditioning) indicates. A key factor in human comfort is humidity control.
