What plug should I use?

Flex chargers have two different plug options, NEMA 6-50 (3-wire) and NEMA 14-50 (4-wire). Either option will work, and your electrician can help determine what’s best or which receptacle is already installed in your home. You may prefer NEMA 6-50 because it does not require an additional neutral wire, which may slightly reduce installation cost compared to NEMA 14-50. Outside of EV charging, NEMA 6-50 outlets are commonly used with welders and NEMA 14-50 outlets are commonly used with electric ovens or recreational vehicles.
