Based on the 2020 National Electrical Code. Part 1 of this two-part series taught you how to calculate branch-circuit loads. Now let's review how to perform feeder and service load calculations.

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 ...

If you’re building something that moves, chances are you’ll be using an electric motor. There are tens of thousands of different motors out there, each with their own properties, speeds, torque, and ...

The easiest way to design a linear-motion system is to add components one by one. Then, step-by-step calculations relate input to power dissipated moving a load in a specific amount of time. Linear ...
