Designers of early indoor LED light bulbs faced numerous technical hurdles, including AC-to-DC conversion, thermal heat-sinking, constraints imposed by current bulb sizes, electrical transients, and ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

Understanding the advantages, limitations, and use cases of each technology helps engineers create reliable consumer products.

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

Power protection is like insurance: You pay for it, yet hope you don’t need it. But it’s not a simple “purchase.” The first protection question is, “What am I seeking to protect and against what event ...

A short circuit happens suddenly, and the results can be minimal, such as tripped circuits, or it can become hazardous, causing sparks and fire. A short circuit can occur in older wiring or newer ...
