Each motor branch circuit must be protected against short circuit and ground faults by an overcurrent device sized no greater than the percentages listed in Table 430.52. A branch-circuit ...

Courtesy of www.MikeHolt.com All questions and answers are based on the 2020 NEC. Q. What is the Code definition of “electronically protected” as related to motors? A. The NEC defines an ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Most operational amplifiers (op amps) have input and output electrostatic discharge (ESD) protection diodes, as shown in Figure 1. These diodes are designed for protection from ESD damage during ...

The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...

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 ...

Once an engineer has designed the audio circuit of an amplifier, it would be nice to think that most of their task is complete. However, from a system perspective, that is far from true. At the very ...
