Power Cords

90° Elbow Plug × Wire Leads

90° Elbow Plug × Spade Terminals

NEMA 14-30 Plug

Connect equipment and devices to a power supply.

Cords with a NEMA 14-30 or 14-50 plug are often used to power electric vehicles. They have a high current rating.

Cords with a 90° elbow plug fit flush against a wall outlet, so they fit behind machinery or in areas where space is tight.

The insulation on STW and SJTW cords resists water. SRDT cords are for use with high-current equipment, such as ranges and dryers.
