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 ...

When is a fuse more desirable than a circuit breaker as an overcurrent protection device? a. A fuse is never more desirable in a circuit b. A fuse is always more desirable in a circuit c. A fuse is ...

Why are people scared of fuses? Many people think that fuses are unsafe, but this couldn't be further from the truth. A properly installed fuse is just as safe as a circuit breaker, but there are many ...

It's only a circuit breaker. How hard could it be? A surprising number of engineers specify the wrong type of circuit breaker to protect their equipment. Engineers ...

Churning with voltage and resembling an explosion at the wire factory, the breaker panel exudes mystique. But it's just a big switch, filled with other smaller ­switches, which lead to the switches ...

This is the second part of a two-part series on the methodologies used to find the short circuit current duties of circuit breakers and fuses. The first part, Short Circuit Current Duties of Circuit ...
