with added short-circuit protection and built-in diagnostics. Transistor Q1 is an inexpensive driver that can withstand a few hundred volts and drive a few hundred milliamps. The microcontroller ...

Conductor overload protection is not required where circuit interruption would create a hazard (e.g., a fire pump). Short-circuit protection is still required. You can use the next higher standard ...

To prevent a motor from burning up, you must provide a means of protecting it from overcurrent (overload, short circuit, or ground fault). If you can remember not to confuse motor protection with ...
