Daylight harvesting reduces energy consumption by using daylight in place of, or to augment, electric lighting to light a space. Lighting control systems are used to dim or switch electric lighting in response to changing daylight availability; when daylight penetrates into spaces, the amount of electric lighting needed is reduced. Now, new technology has come onto the market with control for up to three dimming zones, combining electric lighting and control circuits within a single interlocked armor. The new MC Luminary MultiZone™ cable is the first product specifically designed to meet California’s strict daylight harvesting requirements, which are rapidly being adopted by jurisdictions around the United States.

Last year, we presented two separate articles on the topic of safety and the correlation between safety and productivity (“A Safe Job Site Is a Productive Job Site” [2016 May/June Insights] and “Predict & Prevent” [2016 Sept/Oct Insights]). We have already presented the data that shows “why” this connection is important to an electrical contractor, and we have already presented the information that explains “what” needs to be done in order to gather relevant information from the field. In this article, we will dive deeper into “how” to use critical business processes to alleviate the risk of safety-related issues before they occur. Not unlike quality and customer care, the safety of any job site starts with the board of directors. If the executives, manager, and supervisors think safety first, then the job sites will be safer.

Customer wants and needs all too often get forgotten as we get too obsessed with meeting National Electrical Code (NEC) requirements. We need to be as obsessed about meeting our customer wants and needs as we are with meeting what, in reality, is a bare minimum for electrical safety. It may shock you to learn that a system designed to meet the minimum requirements of the NEC may not be adequate for the application. This article will discuss a few key areas where your design may need to exceed the bare minimum requirements of the NEC.

Constant changes to LED technology can make keeping up with LED developments seem like a full-time job. Color tuning, and specifically tunable white, is one of today’s most intriguing control opportunities, but where do you start to ensure you’re making the best fixture and control decisions? Historically, fixtures have been purchased with a specific color temperature; however, emerging studies are confirming the human centric benefits of being able to change, or tune, a fixture’s correlated color temperature (CCT). Tunable white applications use more sophisticated LED drivers and light engines to control both the color temperature and the intensity of a fixture. The right solution for any project begins with asking the right questions.

A recent fire that engulfed an industrial site in New York is said to have been caused by the ignition of highly-combustible cardboard. One hundred members of the local fire department responded to the blaze, which had caused the roof and some of the walls of the building to collapse. The fire quickly took over the six-block-long building and prompted the authorities to issue a shelter-in-place order for all nearby residents. What caused the ignition of the cardboard? The failure of a single light bulb.

Later this year, the National Fire Protection Association (NFPA) will introduce the 70E: Standard for Electrical Safety in the Workplace® 2018. The electrical contractor community awaits each new edition of the standard with a mixture of curiosity, optimism, and dread – with good reason. Even seemingly minor changes can have a major impact on a contractor’s established workflow. Most changes necessitate additional training, and some require electrical workers to invest in new or updated equipment. To help electrical contractors prepare, here’s a peek at a few of the more notable changes to the NFPA 70E standard that will impact their day-to-day work practices.
