1-1/4" SEU CONNECTOR (Product Description)
A 1-1/4-inch SEU connector is a mechanical service entrance cable fitting used to secure SEU (Service Entrance Unarmored) cable where it enters an electrical panel, meter socket, or service enclosure.
Product Description
This connector is designed specifically for SEU cable, which is commonly used for service feeds and feeder runs in residential and light commercial electrical systems. The fitting clamps onto the outer jacket of the SEU cable and secures it into a 1-1/4" knockout in the enclosure.
It provides both mechanical retention and strain relief, preventing the cable from being pulled out or damaged at the point of entry. The body is typically made of die-cast zinc or aluminum, with an internal clamping mechanism that tightens onto the cable without cutting into insulation.
