RVBOATPAT Single-Sided Entry 4 Port Insulated Connector Multi Tap Connector 4-14 AWG Aluminum to Copper Wire Connectors Slotted Allen Hex - 6 Pack

4 port copper aluminum connectors work for 4 AWG, 6 AWG, 8 AWG, 10 AWG, 12 AWG and 14 AWG wire gauge. Aluminum to copper wire connectors allow copper wire to copper wire, aluminum wire to aluminum wire and copper wire to aluminum wire connections, making the insulated connector the best alternative for safely splicing aluminum wire to copper wire. Insulated connector is safer and more convenient than a butterfly nut connector, with larger wire diameter range and higher current, specially designed for those who need easy connection and use. It uses a hex screw to fix the wires and comes with lubricating oil with antioxidant properties in the ports. Electrical power connectors are insulated with high dielectric strength plastic sol for improved chemical protection and wear resistance. The design purpose of multi tap connector is to ensure the safety of aluminum to copper connections and to prevent electrical fires caused by overheating of aluminum wires due to conductor mixing.
