About NEMA Connectors

NEMA connectors are named according to their type, followed by the number of poles and wires attached to them. For instance, a 2-pole, 3-wire connector is called L2P3W.The first line shows how many amps there are in the outlet. Then it shows what type of socket it is (receptacle/plug).

There are many different kinds of electrical outlets and power adapter. Some are grounded, some are not. The ones that aren’t ground themselves are called “unprotected”. The ones that are ground are called “grounded”.

A small hole near the end is used for convenient manufacturing. Padlocks are available to fit this hole. Hazardous equipment may be locked out with a padlock. Locks were invented to prevent the plug being inserted into the socket.

The ground wire is connected to the frame of the house. All three phases of power are provided by the same circuit breaker. There are four ground wires, but only one is attached to the frame of the building.

Two of them are connected to the ground rod, and the other two are connected to each other.


All NEMA 6 plugs are grounded, and the current rating is 20 amps. They resemble the 5-15, and have blades rotated 90 degrees opposite the line blades. The 6-15 plug looks similar to the 5-15 plug, but with collineral horizontal pins. it is a good power adapter.

The 6-20 plug has a T shaped hole to fit both the 6-15 and 6-20 plugs.

Receptacles are devices that connect electrical circuits together. They are generally made of metal. There are different types of receptacles. Some have 3 prongs while others have 2 prongs. Sometimes there are two different sizes of receptacles.

This is because some people use them differently. For example, a smaller size is used for outlets in kitchens and bathrooms while a larger size is used for outlets near the main entrance of homes.

It is common for many  manufacturers of electric vehicle charging stations to equip their 30-40 amp level 2 EVSEs with an 18-50 plug on a shorter cord. This is the most common plug size for North American electrical outlets.

Manufacturers are now specifying this plug size instead of the older 6-50 plug.
