  • Automations Controls – Part 1

    It was a dark and stormy night. Outside the wind was howling, rain pouring down as if from a fire hose. But inside, I was stretched out in front of the television, aimlessly clicking the channel button on the remote.

    Sigh... nothing good on tonight to pass the time.

  • Bringing Fused Protection to Today’s PV Arrays

    With solar photovoltaic (PV) arrays, whether on a homeowner’s roof or spread across acres in a utility installation, it’s the panels that get most of the attention. However, it’s the racks, conductors, overcurrent protective devices and other “balance-of-system” equipment that now is more significant in a project’s total cost.

  • 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.

  • Office Lighting Controls Optimized for Occupancy

    The other night — somewhere between midnight and 1 AM — I woke up and couldn't get back to sleep. Figured I might as well burn a little midnight oil and make productive use of my insomnia.

  • Specifying Flexible Conduit with Extreme Temperatures in Mind

    Introduction
    Most electrical wiring and conduits operate within a “comfortable” range of operating temperatures, but there are also many others that experience either extremely low or high temperatures or both. All of these cases require conduits specially designed to deliver their rated performance, including flexibility and protection, under conditions beyond those of standard types.
