  • New Combination Products Give Cables More Control

    There was a time when lighting and other switched electrical equipment was designed for simple on/off operation, making wiring a simple affair. Contractors only needed to install a single run of power cabling to meet operational needs. Today, though, both clients and ambitious energy standards are requiring greater control over building systems, specifying products like dimmable lighting and variable-speed fans, and the need for additional runs of control/signal cable can make installation a much more complicated task.

  • Giving Aluminum Wiring a Fresh Look

    While many know of the travails suffered by the owners of buildings wired with aluminum conductors back in the 1950s and 1960s, far fewer understand just how much improved today’s aluminum wiring products are from those used five decades ago. While the older offerings were not designed for building applications, today’s aluminum wire features alloys designed specifically for use in local distribution systems. In fact, in some cases aluminum wire can be a better option than traditional copper conductors in both cost and performance.

  • How Smart Sensors Are Revolutionizing Building Management

    When most people hear the term “Big Data,” they think of the IBM Watson supercomputer crunching billions of numbers in a lonely data center. But Big Data comes in small, distributed packages, too.

    For example, smart sensors installed in lighting luminaires make it possible to gather and analyze vast amounts of information to help make building management less costly and more efficient.

  • LED Technology Gives Contractors Flexible Entry Points

    Think of LED lighting as the “gradual” revolution. Electrical contractors don’t have to go all-in overnight. They can enter the LED world in an unhurried way, based largely on available rebates and what their customers have in mind.

    Contractors can start one lamp at a time if they choose, replacing a fluorescent lamp with a T8 LED lamp.

  • Non-Metallic Enclosures Solves the Need for Major Utility Company to Reliably Protect Pump Controls in an Extremely Hot and Humid Environment

    The Situation:
    A large east coast utility company was experiencing failure of controls installed in manholes vaults underground that were monitoring the water level in steam tunnels and underground vaults. The controls managed floats and pumps for pumping water and fluid from steam tunnel vaults situated below city level.

  • PVC-Free Conduit Jackets Limit Combustion Products

    LSZH Conduit
    Polyvinyl chloride (PVC) is by far the most widely used jacketing material for electrical insulation, thanks to inherent benefits such as dry and wet electrical performance, flexibility, long life, fire retardance, cold temperature resistance, chemical resistance, and ruggedness. But in a fire, PVC releases fumes collectively called halogens that include hydrogen chloride, hydrogen fluoride, and hydrogen bromide gases, as well as other deadly combustion products.
