Puzzled by choosing circuit protection devices? Follow these guidelines and your electrical system will fall into place. Is it sufficient to select protective devices based entirely on their ability ...

I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...

Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

The global demand for green energy sources is driving strong market growth for solar power systems. Although a great deal of development work is still focused on making PV (photovoltaic) energy ...

Downtime has taken on enormous importance as companies struggle to compete in a global market and a global downturn. Managers are in hot pursuit of technologies that reduce business interruptions, no ...

[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future.

Security and fire alarm systems are designed for operation within specified current and voltage ratings. If these ratings are exceeded due to short-circuit or voltage transients, components may ...

Circuit breakers now sport advanced features that include remote control and operational status reporting. Engineers have long considered circuit protection a stable if somewhat unglamorous area.
