Electrical Industry Articles and Stories

The COVID-19 pandemic has hit most businesses very hard. Many industries have seen total shutdowns that lasted for as long as several months. Others, like many restaurants and retailers, have had to patch together short-term solutions, like curbside pickup, to minimize physical interactions. One market that’s set to boom, however, as businesses begin reopening, is commercial video conferencing, which allows important face-to-face meetings to continue happening, even as far as a continent or more away.

In a recent survey conducted by Electrical Contractor magazine, respondents cited skilled labor shortages, product availability, and compressed timelines among their broad-based concerns. Contractors are looking for lighting control solutions that help alleviate these issues by reducing installation time, minimizing risk, and adding value to their jobs. Wireless lighting control solutions and quick estimating software can help.

The weakest links in any electrical distribution system are those locations where connections are made. Secure tap, terminal and splice connections are critical to a system’s safety and reliability. Electrical contractors have a number of options when it comes to the connectors they use in these applications, with mechanical- and compression-style connectors being the most common.

When I first strapped on my electrician's tool belt, control power was relatively simple. Many times, the control power came directly from line voltage. For example, take one leg of the 480 VAC incoming power on a starter and voila … a 277-volt control circuit.

As long as the coil on the starter was rated for 480, no problem.

Your local streets might be looking a little different lately when you’re driving home at night. It could be because they no longer feature that yellow-orange glow produced by the high-intensity discharge lamps that have illuminated U.S. streets for decades. Cities across the country are rapidly upgrading to LED streetlights, leading to improved illumination and significant energy savings.

Vive installs 70% faster than wired solutions. You can install a switch and as sensor in as little as 15 minutes—no new wiring required. And you can mount wireless devices to any surface without cutting holes or running wire.
