3M 31045 Copper Compression Lug 1H

Product Description

The 3M 31045 is a 1H copper compression lug designed for making secure, low-resistance terminations on copper conductors. Compression lugs of this type are crimped onto the conductor using a hydraulic or ratchet compression tool, creating a gas-tight, vibration-resistant connection. This lug is used in electrical distribution and wiring applications where a reliable, permanent conductor termination is required. Licensed electricians and electrical contractors install this type of fitting as part of panel connections, equipment terminations, and power distribution assemblies.

The 3M 31045 copper compression lug is suited for residential and commercial electrical installations. It is typically used where conductors must be terminated at bus bars, switchgear, panelboards, or equipment terminals. The 1H designation indicates the specific barrel and tongue configuration for this lug. Installation is performed by qualified electricians following applicable NEC guidelines.

Key Features

• Copper construction provides excellent conductivity and corrosion resistance
• Compression-style termination creates a gas-tight, vibration-resistant connection
• 1H configuration suits specific conductor and tongue sizing requirements
• Compatible with standard hydraulic or ratchet compression tooling
• Designed for permanent, high-integrity conductor terminations

Compatibility

Designed as an OEM-style compression lug for use in standard electrical conductor termination applications where a 1H copper compression lug is specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before beginning any termination work. Use the correct compression tool and die set specified for this lug to ensure a proper crimp. Do not use open-barrel or mechanical-style tooling as a substitute for compression tooling.
