Wire Connectors

Wire connectors help electricians and maintenance professionals join, splice, or terminate wire during electrical installation, repair, and maintenance work. This category includes twist-on and wing-type connectors for copper-to-copper splices, along with crimp-style butt splices, female disconnects, spade terminals, and ring terminals for compatible wire, tabs, and studs.

Wire Connector Buying Guide

Choose wire connectors by first identifying whether the job calls for a copper-to-copper splice or a crimped wire termination. Then compare the connector style, stated wire range, compatible tab or stud size where applicable, and package quantity needed for the work.

Use Cases

Match the connector to the connection

Use twist-on or wing-type connectors for copper-to-copper wire splices. Choose butt splices to join compatible wires with a crimp, female disconnects for compatible tabs, spade terminals for compatible studs, and ring terminals for compatible stud sizes.

How to Choose

Check fit before selecting

For crimp connectors and terminals, match the listed AWG range to the wire and verify the tab or stud size required. For splice connectors, choose the style and package quantity that suit the wiring task.

Applications

Support installation, repair, and maintenance

Products represented here support everyday wiring work, electrical repairs, building wiring, lighting fixtures, luminaires, signs, and electrical maintenance tasks.

Additional Info

Compare handling and protective features

Wing-type connectors provide offset knurled wings for grip and twisting leverage. Several splice connectors use square-wire springs and deep-skirt shells to hold conductors and help cover stripped wire ends.

Represented package quantities range from 15 to 500 connectors or terminals.

22-10 AWGWire ranges shown

Crimp-style options shown cover stated ranges from 22-16 AWG through 12-10 AWG.

Up to 1,000 VStated voltage rating

One red connector is rated up to 1,000 V for lighting fixtures, luminaires, and signs.

105°CHeat distortion resistance

Several wing-type connectors resist heat distortion up to 105°C (221°F).

Planning Guide

Plan the right fit before choosing

Start With the Connection Type

Select a splice connector or a crimp termination

The category includes two distinct approaches. Twist-on and wing-type models are made for copper-to-copper splices and twist onto grouped conductors. Crimp-type products provide connections for joining wires or terminating compatible wire to tabs and studs.

  • Twist-on connectors offer a compact twisting style for copper-to-copper connections.
  • Wing-type connectors add offset, knurled wings for a firm grip and more twisting leverage.
  • Butt splices join compatible wire sizes with a crimped connection.
  • Female disconnects, spade terminals, and ring terminals support connections to compatible tabs or studs.
Confirm Compatibility

Compare wire range, contact size, and stated ratings

Crimp products have specific compatibility details that should match the job. Available examples include female disconnects and spade terminals for 22-16 AWG wire, a butt splice for 16-14 AWG wire, and a ring terminal for 12-10 AWG wire. Tab and stud dimensions also vary by terminal style.

  • Female disconnects connect 22-16 AWG wire to compatible 0.250 in. tabs.
  • Red spade terminals fit 22-16 AWG wire and compatible size 4-6 studs.
  • Yellow ring terminals fit 12-10 AWG wire and compatible 5/16 in. to 3/8 in. studs.
  • The blue butt splice is for 16-14 AWG wire and has a 600 V maximum rating.
Plan for Handling and Quantity

Choose features that fit the pace and conditions of the work

For repeated splice work, consider grip, shell coverage, environmental resistance, and pack size. Twist-on options may have color-coded housings and chemical-resistant shells. Wing-type options use adjusting plated springs and deep-skirt shells, with stated resistance to heat distortion up to 105°C (221°F).

  • Deep-skirt and long-skirt designs help reduce exposed bare wire at the connection.
  • Square-wire springs help grip conductors; adjusting springs conform to splice shape and size.
  • Some housings resist hydrocarbons and diluted acid or alkaline solutions.
  • Package quantities range from 15 pieces to 500 pieces among the products represented.
FAQ

Common questions before buying

What wire connectors are available for copper-to-copper splices?

The category includes twist-on and wing-type connectors designed for copper-to-copper wire connections and splices.

What is the difference between a butt splice and a terminal?

A butt splice joins compatible wires with a crimped connection. A terminal crimps onto wire to connect it to a compatible tab or stud.

How do I choose a crimp connector by wire size?

Match the connector's stated AWG range to the wire. Examples shown include 22-16 AWG, 16-14 AWG, and 12-10 AWG options.

Are there connectors for lighting fixtures and signs?

One red copper wire connector is rated up to 1,000 V for lighting fixtures, luminaires, and signs, and up to 600 V for building wire. Verify that stated rating against the application requirements.
