This 6-pack of 3 Port Dual Entry Black Insulated Connectors is designed for efficient splicing of 1/0 to 14 AWG wires. Each connector supports multiple wire gauges including 1/0, 2, 4, 6, 8, 10, 12, and 14 AWG, making them suitable for a wide range of electrical applications. The connectors feature a dual-entry design, allowing connections between aluminum to aluminum, copper to copper, or aluminum to copper wires. Constructed with a durable aluminum body and secured using 3/16 in. Allen hex screws, they provide strong, stable connections. Pre-lubricated with anti-oxidant grease, they resist corrosion and maintain conductivity over time. The high dielectric strength plastic sol insulation offers enhanced protection against chemicals, wear, and environmental stress, ensuring long-lasting safety. These insulated connectors are a safer and more convenient alternative to traditional wing nut connectors, supporting higher current loads and accommodating a wider range of wire sizes. Their secure design also simplifies inspections and reduces the risk of overheating caused by mixed-metal connections. Ideal for residential, commercial, or industrial use, these connectors ensure reliable performance and safe wire splicing in a compact, easy-to-install form.
