3M Color Coded Connectors

The 3M Highland color-coded connectors are for general wiring-making it easy to match the right connector to the right-sized wire. The internal, round wire spring ensures smooth twist-on and a secure connection for years to come. These connectors are UL listed and CSA approved, working equally well with solid and stranded wire. The H-29 and H-30 are rated to 300V and the H-31, H-33 and H-35 are rated to 600V.
