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 ...

In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...

Benefits of an e-fuse solution. Optimal voltage range for e-fuse applications. Target applications for e-fuse devices. The trend toward higher bus voltages creates the need for a robust circuit ...

The multi-wire branch is here to stay; so is ground fault protection. But we should unite these technologies only when it’s a good match. Ground-fault protection and the multi-wire branch circuit ...

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 ...
