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 ...

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 ...

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 ...

An overload or short circuit in a fuse or mini circuit breaker can lead to undersupply or failure of an entire 24-V dc power-supply system. Selectivity protection using an electronic fuse offers a ...

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 ...

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.

Protecting circuits and equipment from overcurrent from overcurrent involves more than simply selecting a fuse or breaker from a table Art. 240, which is divided into ...
