3M 7010348891 Wire Connector 18-14 Awg Orange 600V

Product Description

The 3M 7010348891 is an orange twist-on wire connector designed for joining 18 to 14 AWG conductors in residential and commercial electrical applications. Sold as the H-31 variant in the Highland series, this connector is rated for 600 volts maximum in building wire and up to 1000 volts maximum when used in signs or lighting fixtures (luminaires). The spring-steel internal coil grips conductors securely without soldering or taping. Licensed electricians and qualified electrical tradespeople install these connectors in junction boxes, panel wiring, and fixture rough-in work where a reliable, code-compliant termination is required.

This connector is suited for light commercial and residential wiring projects where 18 to 14 AWG conductors need to be spliced or terminated. The orange color-coding identifies the H-31 wire range at a glance during installation and inspection. Common applications include branch circuit wiring, fixture wiring, and control wiring inside enclosures. The elevated voltage rating makes these connectors appropriate for sign and luminaire installations in addition to standard building wire runs.

Key Features

• Rated 600V maximum in building wire; 1000V maximum in signs and lighting fixtures (luminaires)
• Compatible with 18 to 14 AWG conductors
• Orange color-coding identifies the H-31 wire range for fast identification
• Twist-on design requires no tape or solder for a secure connection
• Sold in a pouch format for convenient job-site use

Compatibility

Designed as an OEM-style twist-on connector for use with 18 to 14 AWG building wire, sign wiring, and luminaire wiring where a 600V or 1000V rated termination is required.

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 making any wire connections. Strip conductors to the length recommended for the connector size, hold conductors parallel, and twist the connector clockwise until firm resistance is felt. Do not overtighten to the point of conductor damage or insulation deformation.
