Wire nut connectors are designed for general purpose applications requiring the connection of two or more copper wires. Wire connectors feature a straight type polypropylene shell with side knurling for an easy grip. The inner spring is zinc-plated to resist corrosion and has a tight square profiel to make quick secure contact with wires and ensure connections with positive continuity. These all purpose connectors require fewer turns to meet required torque and meet or exceed UL pull out and dielectric test requirements. The tough thermoplastic shell shields against environmental extremes and resists chemical action from hydrocarbons, diluted acid or alkaline solutions. The high-dielectric shell also features a deep skirt design to prevent exposure to bare wire. Flame-retardant properties resist heat distortion up to 105 C (221 F). Use for air conditioners, ceiling fans, doorbells, indoor lighting, switches, thermostats, ballasts, large and small appliances.
