Southwire 874A 1-1/4 Inch Seu Connector Weathertight

Product Description

The SOUTHWIRE 874A is a weathertight SEU connector designed for use with service entrance cable in residential and light commercial electrical installations. This connector provides a secure, weather-resistant termination point where SEU cable enters a meter socket, load center, or service equipment enclosure. The 874A accepts 1-1/4 inch trade size cable entry, making it suitable for larger service entrance conductors commonly found in 200-amp residential services. Licensed electricians install this fitting as part of a complete service entrance assembly to maintain code-compliant, moisture-resistant connections at the point of entry.

This connector is used at service entrance locations where SEU cable transitions into electrical enclosures, including meter bases and main disconnect panels. The weathertight design helps prevent moisture intrusion at cable entry points, which is critical for outdoor service entrance applications. It is appropriate for residential new construction, service upgrades, and service restoration work performed by licensed electrical contractors.

Key Features

• Weathertight construction for moisture-resistant service entrance terminations
• 1-1/4 inch trade size entry for larger SEU cable conductors
• Designed for use with SEU-type service entrance cable
• Suitable for meter socket and load center enclosure applications
• SOUTHWIRE manufacture for consistent dimensional fit with standard service equipment knockouts

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 1-1/4 inch knockouts in residential and light commercial service entrance enclosures accepting SEU cable.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and verify absence of voltage on all service conductors before handling any service entrance components. Ensure the knockout size in the enclosure matches the 1-1/4 inch trade size of this connector before installation. Avoid over-tightening the connector body, which can damage the cable jacket and compromise the weathertight seal.
