It takes a lot more than men in space suits and telescopes to study the universe. One important technology incorporated into space exploration is circuit protection. Fuses or circuit protectors are ...

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 ...

The rising costs of telecommunication system failures, the increased use of unattended equipment in remote locations, and the high service expectations of subscribers all make the loss of a telephone ...

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.

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 ...

Note: This article is based on the 2011 NEC. Overcurrent exists when current exceeds the rating of equipment or the ampacity of a conductor. This can be due to an overload, short circuit, or ground ...

My introduction to circuit protection came at the tender age of eight. Being a curious lad with an inventive – and apparently self-destructive – bent, I decided to make my mother a lamp. I put a hose ...

Surge protection for an electrical panel controls how transient voltages enter and spread through branch circuits inside the panel, limiting internal equipment damage when external or switching surges ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.

Circuit breaker keeps tripping is a warning, not a nuisance. Repeated trips can signal overloads, wiring faults, ground faults, or coordination problems, and misreading the cause risks overheating, ...
