- Space-saving design: lever wire nut connectors are specially designed to save space and prevent wires from twisting when joining conductors. - Easy to use: insulate the wire to 9-10 mm, press the orange pull rod to 90°, slide the wire in, then press the pull rod down. When the cable is inserted into the lever’s plug and locked, the cable will not loosen. The connectors resist pulling. - Time- and labor-saving: quickly connect and remove wires. To replace a cable, simply lift the orange lever, remove the unused wire, and insert a new one. A test hole on the surface lets you check whether the cable is current. - Wide compatibility: eight configuration options (2, 3, 4, 5, 6, 8, 10, 12 connections) to meet different wiring needs. Connect any combination of 28-12 AWG solid, stranded, and flexible copper wires. Commonly used in sockets, switches, lamps, switch boxes, chandeliers, cars, speakers, fan controls, and more.
