Choosing a Hubbell pin-and-sleeve connector
Start with the current and voltage, phase, number of poles, grounding configuration, and color or keying required by your installation. Then choose the matching plug, receptacle, or connector body and confirm the enclosure and environmental requirements.
Browse Hubbell productsMatch the connection to the installation
The right Hubbell connection depends on more than amperage alone. Compare the electrical configuration and the mating component so the finished installation has the right fit for its environment.
