Duraline provides durable and easy-to-use L14-30 generator power cable solutions. Commonly found in household and commercial generators, the L14-30 generator power cables provides split-phase power output. Our specialty-made L14-30 products allow maximum use of your generator and are designed to be highly durable. Our L14-30 product line includes spiders and splitters, extension cables, power stringers, and even replacement parts. Duraline can also produce custom L14-30 parts to suit any need. Our L14-30 products provide solutions for any circumstance!

These L14-30 connectors are in place to remain secure in high-vibration applications and prevent accidental disconnection. The NEMA L14-30 connectors are built to handle demanding, repetitive-use applications and are more durable than standard turn-lock connectors. A quarter-turn locks the L14-30 in place to remain secure in high-vibration applications and prevent accidental disconnection. Protect computers and other sensitive equipment from electromagnetic interference (EMI) with the NEMA L14-30. Also known as isolated ground receptacles, the L14-30s have a ground terminal insulated from the mounting strap so you can run an isolated ground wire through the conduit.

NEMA L14 are three-pole and ground connectors rated for 125/250 V. Intended for three-pole, four-wire hot-hot-neutral-ground circuits with nominal supply voltages of 240 or 208 V hot-to-hot and 120 V hot-to-neutral. These L14-30 connectors are standard on household backup generators and racks of power amplifiers in large audio systems.
