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.

High power connectors come in three sizes with each size rated for 50 amp, amp, and amp current capacity

Make a quick, secure wire connection without crimping. For technical drawings and 3-D models, click on a part number. Suitable for use in tight spaces, these connectors have a narrow profile that takes up less space than standard wire splicing connectors. Use them to make quick, secure wire connections without crimping. Grounding connectors have a hole in the top that allows a single ground wire through while multiple wires remain connected inside. Make quick, watertight connections for underground applications without any crimping. These connectors are filled with silicone, so they seal out moisture and prevent corrosion.

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. Never use tape in place of wire nuts—it's simply not secure enough, and it's vulnerable to damage. Some people like to use wire nuts and wrap them with tape. This fine to do, but you probably won't find any wire nut manufacturers advising you to do it.

Please improve this article by adding secondary or tertiary sources. 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. He then caps them with a sleeve which he rigidly secures in place by means of the grub screw, which on account of its long thread bearing may be tightened very securely without danger of stripping. These feedthrough connectors are typically green, and are also called "screw-on grounding connectors". Power Distribution Blocks. Quick Splice Connectors. ATC Fuse Holders. Molded Connectors.
