Buying Guide

Match connector to wire gauge

Choose terminals rated for the wire sizes you use — these selections cover 12 AWG down to 24 AWG for both solid and stranded conductors

Prefer lever or reusable designs

Lever-style connectors let you open and reconfigure splices without cutting wires, which is helpful for troubleshooting and future changes

Check port count and capacity

Pick 2- or 3-port connectors according to how many conductors you must join inside the junction box to avoid crowding and ensure secure clamping

Consider pack size vs. project scope

Buy bulk packs for larger jobs or assorted packs for a mix of sizes; larger boxes reduce cost per connector for repeated use

Verify ratings and compatibility

Confirm each connector’s electrical and temperature ratings and that the manufacturer lists compatibility with both solid and stranded conductors for safe splicing
