Electrical Industry Articles and Stories

Whole-home surge protection has become a much bigger issue for residential electrical contractors in the last year as local authorities have begun adopting the 2020 edition of the National Electrical Code (NEC).

Water and electricity don’t mix – that’s something we all learn at a pretty early age. But still, there are times when even the wettest locations require power. In applications from pool lighting to irrigation systems and outdoor outlets, contractors are often called on to make electrical connections that can remain watertight over years of use.

Flashlights used to be just, well, flashlights – handy tools for bringing a little illumination to whatever task was at hand. They also could be a little undependable in the old days. Battery strength was always a question, especially if they hadn’t been used in a while.

Earlier this year at the Light + Building 2018 trade show in Frankfurt, Germany, Philips Lighting announced a string of new initiatives aimed at the transition to more LED lamps as well as the inclusion of LEDs into the “Internet of Things” (IoT) in homes and buildings worldwide.

First the company announced IoT platform called Interact, designed to handle data collected from connected light points, sensors, devices and systems.

In new construction, sustainable building practices are becoming the norm. But even in existing buildings, simple strategies can be implemented quickly and easily to address inefficiencies, reduce energy use, improve comfort, and enhance productivity in the space.

Some facilities are changing their requirements for motor and appliance installations. This could be due to OSHA Lock-out and Tag-out requirements or NFPA 70E. The change is toward using pin and sleeve devices instead of having a hard-wired installation.

Safety requirements often have the maintenance person checking for the absence of voltage before touching. The rules are quite specific and are enforced by OSHA.
