Wire Connectors

Wire Connectors for Safe & Reliable Electrical Connections

Wire connectors, commonly referred to as wire nuts, are essential electrical components used to securely join two or more electrical wires. Their primary function is to insulate and protect live wire connections, preventing accidental contact, short circuits, and electrical hazards.

At Lighting and Supplies, we offer a complete range of wire connectors designed for residential, commercial, and industrial electrical installations. Our selection supports safe power distribution, code compliance, and long-term connection reliability.

What Are Wire Connectors?

Wire connectors are protective caps or devices that fasten electrical conductors together inside junction boxes, fixtures, and enclosures. They prevent exposed wires from contacting metal surfaces or other conductors, reducing the risk of electrical faults and fire hazards.

Wire connectors are available in multiple sizes, materials, and connection styles to accommodate different wire gauges, conductor counts, and application requirements. Proper selection is critical for maintaining electrical safety and performance.

Before installing any wire connector, power to the circuit must always be turned off.

Why Proper Wire Connector Selection Matters

Electrical conductors expand when heated and contract when cooled as current flows through them. If a wire connector is undersized or improperly rated, it may loosen over time, potentially exposing live wiring.

Using a wire connector that matches:

• Wire gauge
• Number of conductors
• Application temperature rating

ensures a secure connection that remains stable through thermal expansion and contraction.

Types of Wire Connectors

Wire connectors are designed for specific installation needs and environments. Common types include:

Screw-On Wire Connectors

Standard twist-on connectors used for general electrical wiring. High-temperature versions are available for fixtures and environments exposed to heat.

Economy Wire Connectors

Cost-effective screw-on connectors suitable for light-duty residential wiring and basic electrical projects.

Wing Wire Connectors

Designed with flexible side wings to provide additional grip and torque, making them ideal for larger wire bundles and commercial applications.

Push-In Wire Connectors

Allow conductors to be inserted directly without twisting. These connectors offer fast installation and consistent connection pressure.

Nylon Pigtail & Closed-End Connectors

Used for terminating wires or creating pigtail connections inside electrical boxes.

Tap Splices & Quick Splicers

Enable tapping into an existing wire without cutting it, commonly used for quick modifications and retrofits.

Supporting Insulation & Protection

While electrical tape is not a connector, it is often used alongside wire connectors to provide additional insulation, strain relief, and protection within junction boxes.

Applications for Wire Connectors

Wire connectors are widely used in:

• Residential wiring and lighting installations
• Commercial electrical systems
• Industrial control panels
• Junction boxes and enclosures
• Lighting fixtures and devices
