Adapter #34 30A 14-30 Extension Cord 14-30 plug to 14-30 box outlet - 14-xx Universal Plug optional

  • 8079

Extend your 4 prong Dryer outlet out to your garage. Works well where you need a little more length to plug in your 30A EVSE. Constructed with my super flexible black rubber cord, with a box type outlet on the end. This cable is for 24amp continuous or lower load.

A very handy extension cord to have! Works well in RV parks and other public areas where you need a little more length to plug in your NEMA 14-30 plug equipped 30A EVSE. Custom lengths available, email me and I would be happy to give you a good price.

Built with heavy 10 gauge cable.

14-30 Version (default): all four conductors are passed end to end. Plug only fits into into 14-30 outlets.

14-xx Version: This extension is specifically made for use with Electric Vehicle Charging Stations (EVSE's) and does not provide a neutral connection.

Equipped with the 14-xx universal configuration, It will fit into the 14-50 outlets commonly found in RV parks, sign up at  to see the surprising number of RV parks with 14-50 outlets and Tesla owners sharing their home 14-50 outlets with the community.

The 14-xx universal plug also fits into common 14-30 outlets which are the newer dryer outlets (1996+) allowing you to take it on the road and plug into a friends dryer outlet. The EVSE's and our electric vehicles don’t require the neutral line so this plug works slick by eliminating the neutral blade, we can then plug into several 14-series NEMA outlets.

Also allows you to plug your EVSE into:

NEMA 14-30 (common dryer outlet)

NEMA 14-50 (common Range/Stove outlet, 50amp RV outlet)

NEMA 14-60 (found at some Fair grounds)


Technical note: Electrically EVSE's and our Electric Vehicles do not require a neutral connection, just one ground and two hots, The 14-xx version of this extension is kept a lighter-weight and lower-cost by not carrying the additional unused 4th conductor (neutral), because of this, this cable is not suitable for an RV or other device that requires a neutral.

Please note this cord is rated for 30 amps (24 amps continuous load) The NEC's definition of continuous is one that exceeds 3 hours.
