What is NEMA 14 15 Outlet


Planning to buy an electric vehicle (EV) or already own one? Either way, you may already know that you will need to be charging the vehicle at home. To do this, you need a home EV charger like the EVC 10.


Through this process, you will also need a plug to facilitate the charging process. As of the time of writing, there are only two main types of plugs used for home electric vehicle charging, both rated and standardized by NEMA – the largest and renowned trade association for electrical equipment manufacturers in the United States.

Plugging in-home EV charger

A home electric vehicle charger is the interface between an EV’s battery management and charging system and the electricity passing through you’re your house. This interface needs to be plugged in using an outlet or hardwired. As an unofficial standard, 240V is the sweet spot for an electric vehicle’s power supply.


Modern plug-in home charging setup utilizes a 50 amp, 240V outlet to allow a 40 amp Level 2 charger to be used. But electric standards call for a circuit to be equal to 125 percent of a device’s load.


Home EV charging configuration charges at 10Kw, which is the total power supplied when you multiply the 40 amps by 240 volts. Thus nicely fits the amount of power that most EVs accept.


But you need to choose the standardized outlet for your home EV charging. There are numerous types of outlets you can use for your EV home charging, but today we are going to talk about the NEMA 14-15 outlet.
