Cable supports make the difference between being connected or disconnected in longer vertical raceways

When constructing the Empire State Building in 1930, engineers found that the heavy non-armored electrical cable installed in vertical raceways or risers imposed excessive strain on terminations, panels or other connected devices.

Electronic timer technology has changed the way homeowners interact with timer-enabled switches. Now consumers have the option of intuitive controls and settings that can be changed remotely, using smartphone apps. However, contractors are becoming more involved in the initial setup of these devices, which is a switch from what some installers may be used to. Fortunately, the latest generation of timers is making that process easier, as well, improving the experience for both contractors and their customers.

Hazardous areas require special attention from specifiers. These are areas, as defined in the National Electrical Code, where a combustible atmosphere raises a risk of explosion if sparks or open flames or present. This risk could be the result of flammable gases, combustible vapors, combustible dust or easily ignitable fibers.

Conduit is still the most popular choice for many electrical installations. In industrial applications, conduit gives more choices for the many and various environments found in industrial setting.

For example, food and beverage processing facilities will have harsh environments that can damage conductors easily. Some are caused by the process itself, while other conductor hazards come from the sanitation chemicals and processes used to ensure food and beverage safety.

The use of cable trays is fairly widespread in countries outside the US. However, cable trays are gaining ground here as well. The offset of installation costs to the often more expensive approve cable is one reason. The ease with which reconfiguration of machinery and equipment is another.

Commercial construction is booming but persistent labor shortages can present serious challenges. When it comes to lighting retrofits, simple, scalable wireless solutions can deliver simple-to-design, labor-saving systems that help meet scheduling, budget, and performance requirements on virtually any project.
