The 3M 7010293621 is the Highland H-31 twist-on wire connector, designed to join and insulate 18 to 14 AWG solid or stranded copper conductors. The orange color coding allows electricians to quickly identify the correct connector size without consulting a chart, reducing installation errors on busy job sites. The shell is rated to withstand temperatures up to 221 degrees F (105 degrees C) and the connector is rated for 600 volts, or 1000 volts in sign and lighting fixture applications. UL Listed and CSA Certified, this connector meets the compliance requirements expected on commercial and residential electrical projects.
The H-31 wire connector is suited for residential wiring, commercial electrical rough-in, and fixture installation work. The color-coded orange shell identifies the 18-14 AWG range at a glance, making it practical in panel work, junction boxes, and device outlet wiring. Sold in a 10,000-count keg, this package is sized for electrical contractors and service companies that consume connectors at high volume. The connector works equally well with both solid and stranded wire, covering most field wiring scenarios without requiring a different connector type.
Designed as an OEM-style twist-on wire connector for use in residential and commercial electrical junction, device, and fixture wiring applications where 18-14 AWG conductors are being joined.
Wire connectors of this type are installed by licensed electricians or qualified electrical technicians. De-energize and lock out the circuit at the panel before making any wire connections. Strip conductors to the appropriate length per the connector manufacturer guidance, twist conductors together if joining stranded to solid, then thread the connector clockwise until firm resistance is felt. All work must comply with the applicable edition of the National Electrical Code (NEC) and any local amendments.
