AC WORKS® Wisdom: Differences Between 1430 and 1450

In your home, there are two 4-prong outlets that often get confused because of how similar they look. These are NEMA 14-30R and NEMA 14-50R.

The NEMA 14-30R outlet is used for a clothes dryer, while the NEMA 14-50R outlet is used for an electric cooking range. The 14-50 can also be found in use with 50 Amp RVs, high service generators, and nowadays EV charging. The only difference in appearance is that the neutral pin for NEMA 14-30R is “L” shaped, while the neutral pin for the NEMA 14-50R is “I” shaped like the other pins.

As far as technical differences go, there is one big one. The NEMA 14-50R is rated for 50 Amps while the NEMA 14-30R is rated lower at 30 Amps. Besides that, both offer two hot wires with 125 volts each, which becomes 250 Volts. This is called a 125/250 Volt receptacle.

Keeping the differences in appearance in mind, you will be able to select the correct adapter or extension cord for your needs.
