High-Current Pin-and-Sleeve Connectors
A high current rating makes these connectors suitable for use in industrial machinery and floodlights. Current rating is based on using these connectors with the largest size 194° F rated cable in the wire size range given; current ratings decrease as the cable size decreases. The housing is shatter- and crack-resistant rubber so they can withstand rough environments. Push and twist to join plugs and sockets. When mated, they form a vibration-resistant connection to prevent accidental disconnection. Rated NEMA 3R, they protect against falling liquids and light splashing.
Adapters (sold separately) allow you to change the connector’s gender and make multiple connections from a single power source.
Caps (sold separately) protect connectors when not in use.

High-Current Pin-and-Sleeve Cords
Send power from generators to keep the lights on and equipment running. These cords are often used to convey temporary power during outages or at trade shows and mobile job sites. Able to send currents above 250A, they’re commonly connected to power distribution panels and transfer switches. Push and twist to lock them in place, where they remain secure against high current loads, vibration, and pulling. They don’t require tools to connect or disconnect, making them convenient for short-term setups.
For outdoor use, these cords are rated NEMA 3R for protection from rain, snow, and sleet. They also resist sunlight, oil, and chemicals.
