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.

In Part 1, we saw why we must separate overload protection from fault and short circuit protection for motor circuits. But correctly sizing these different devices can be confusing. And if you follow ...

Many applications involving hydraulics and hydraulically-driven machines have load requirements that fluctuate greatly. In some cases, the peak loads last for relatively short periods during the ...

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 ...
