End view showing metal inserts Twist-on connectors used in a junction box Twist-on wire connectors. 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 ...
A rat-tail splice, also known as a twist splice or a pig-tail splice, is a basic electrical splice that can be done with both solid and stranded wire. It is made by taking two or more bare wires and wrapping them together symmetrically around the common axis of both wires. The bare splice can be insulated with electrical tape or by other means.
Lineman's pliers are used in the electrical trade to cut, straighten, and bend wire, and also to twist wires together when making splices. Lineman's can be used to strip wire and some types of cable, although wire strippers are more commonly used for this purpose as they can strip wire more quickly without damaging the conductors themselves.
Twist-locking types are used for heavy industrial and commercial equipment, where increased protection against accidental disconnection is required. The numerals preceding the hyphen encode the number of poles (current-carrying terminals) and wires connected to it, the voltage, and single- or three-phase power.
Ideal no. 65 Al-Cu twist-on wire nut with distinctive purple color. Special twist-on connectors (or "wire nuts") are available for joining aluminum to copper wire, which are pre-filled with an antioxidant compound made of zinc dust in polybutene base [17] with silicon dioxide added to the compound to abrade the wires. As of 2014 there was only ...
The movable (less fixed) connector is classified as a plug (denoted P), [37] designed to attach to a wire, cable or removable electrical assembly. [38] This convention is currently defined in ASME Y14.44-2008, which supersedes IEEE 200-1975 , which in turn derives from the long-withdrawn MIL-STD-16 (from the 1950s), highlighting the heritage of ...
In British English the general term is socket, but there are numerous common alternatives, including power point, [5] plug socket, [6] wall socket, [7] and wall plug. [8] In American English receptacle and outlet are common, sometimes with qualifiers such as wall outlet , electrical outlet and electrical receptacle , all of these sometimes to ...
The wire may be wrapped directly under the head of a screw, may be held by a metal plate forced against the wire by a screw, or may be held by what is, in effect, a set screw in the side of a metal tube. The wire may be directly stripped of insulation and inserted under the head of a screw or into the terminal.
