  • Material Concerns in Explosion-Proof Product Design

    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.

  • Cable Trays Versus Conduit

    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.

    But, I occasionally hack my way through the residential jungle. Obviously, I'm the chief (and only) electrician in my own home. In fact, a few years back I was able to put my skills to work when we renovated our flat roof carport, morphing it into a laundry room, sewing room, and my personal office.

  • Commercial/Industrial Wiring Devices

    After writing an article about residential wiring devices, I'm finally back to more familiar turf... commercial and industrial environments. But even though I've been around this stuff for a long time, the improvements and innovations continue to keep me interested.

    Some device considerations
    When choosing the right wiring device for a particular operation or use, you must consider various factors.

  • Fuse Specification – Act Fast, or Take Your Time?

    Fuses provide critical protection to electrical systems and the properties those systems serve by opening circuits to shut down the flow of electricity when dangerous overload and short-circuit conditions occur. But sometimes this protective behavior can become a nuisance, as when standard inrush currents trigger a fuse to blow.
