Twist-on wire connectors are a type of electrical connector used to fasten two or more low-voltage or extra-low-voltage electrical conductors. They are widely used in North America and several European countries in residential, commercial and industrial building power wiring, but have been banned in some other jurisdictions. Twist-on connectors are also known as wire nuts , wire connectors , cone connectors , or thimble connectors. Twist-on wire connectors are available in a variety of sizes and shapes. While their exterior covering is typically made from insulating plastic, their means of connection is a tapered coiled metal insert, which threads onto the wires and holds them securely. When such a connector is twisted onto the stripped ends of wires, the wires are drawn into the connector's metal insert and squeezed together inside it. Electrical continuity is maintained both by the direct twisted wire-to-wire contact and by contact with the metal insert.

Timothy Thiele has an associate degree in electronics and is an IBEW Local Union Electrician with over 30 years of experience in residential, commercial, and industrial wiring. While doing almost any kind of electrical wiring in your home, you'll likely run into wire connectors used to make a variety of different circuit wire connections for light fixtures, outlet receptacles, switches, and other devices. The most common type of wire connectors are little round little plastic caps, often called wire nuts , that twist over the bare ends of wires to make tight connections. Wire nut connections are reversible—they can be unscrewed in the future in the event that you need to replace any device. If you ever find wires joined with electrical tape, or the wires are twisted together and then wrapped with electrical tape, get rid of the tape and join the wires with wire nuts.

Quick Splice Connectors. This allows a single-conductor bare wire to be pushed through the hole, forming a "pigtail" section which can be attached to a grounding screw. Yellow twist on wire connectors are s Pre-Made Battery Cables. Manual r AGC fuse holders are used to protect electrical circuits from excess current using standard AGC glass fuses. Twist-on wire connectors are commonly color-coded to indicate the connector size and, hence, their capacity. The orange Pre-made battery cables are available in a variety of different lengths and are manufactured to the highest quality f They are available in vinyl Article Talk. After they cooled, the conductors were wrapped with insulating tape. Seeking a safer, more efficient connection method, Marr, working in his home workshop, developed the first pressure-type wire connector. However, this device used a "grub screw" to hold the pre-twisted conductors in position, as described in the Patent Application and shown in the associated drawing :.
