Basic Walkthrough of Power Cords, Adapters, and Splitters

Whether you’re just starting out or you’re a seasoned craftsman, you should know your way around common tools and technology. Electrical devices that use external power will have at least one plug, but they often have 2 plugs of different kinds for versatility and storage. The plug at the wall or power source will usually be a NEMA plug, which will have two metal prongs and sometimes a grounding prong beneath them. The other kind you might see are IEC plugs, which have 6 pairs of shapes, and are often seen at the body of a product connecting it to a cord, power box, or adapter.

The shape and type of a plug are related to the voltage the device uses, and indicative of how much of it that particular cord is meant to run. NEMA power cords are designed to be able to handle a wide breadth of current, which allows them to be so standard.

This video goes a little deeper into the types of power cords and how you could go about allocating energy from a generator with different combinations of splitters and custom extension cords. The foundation of using a generator like this is knowing exactly how much energy it takes to power your machinery. Obviously, the math for a commercial building would be different than trying to arrange this for your home, but they rely on the same basic principle. Videos like this are a great resource for people trying to learn to take care of their homes right.
