The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

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 ...

Dear James: I am concerned about a fire from an electrical issue in my older house. What are the differences among fuses, breakers, GFCI and AFCI, and which are best? — Peggy T. Dear Peggy: You are ...
