The NEMA Configuration Guide is a free, useful application for the professional electrician, electrician, or electrical professional to have on their phone. It's a must-have tool to help you make the right decision when you're in the field, whether you are electrician or electrical professional.
It's so easy to use. Just plug in the plug you know, and it'll tell you what you have. This way, you don't have to check your equipment's configuration.
If you don't know what you have, you can search for it. It's very easy to do. You just need to type in the voltage, amperage, or the number of poles.
You can also use the handy plug/receptacles cross reference to find the right plug for your equipment.
