Joining Two Electrical Cables Together

These were common in the 70 s when aluminum wiring was used to supply 15 20 amp circuits in residential and some commercial structures.

Joining two electrical cables together. Line up the wire ends then tighten electrical caps photo 1. A solder join wires twisted together not so good. Bend the ends of the wires over each other at right angles and twist them around each other. The best way to strip wires is to use a pair of basic wire strippers.

How to twist electrical wires together when making a splice for light wire such as stereo speaker wires when two wires are joined cross about two inches of each end of prepared wire. Single screw point terminal as the name implies each terminal has just one large screw which is used to secure all the cable cores being joined together. Https youtu be 3kaisyrpykg the secrets of welding. How to do proper joint of electric wire.

Install the wire connector place the wire nut connector over all of the wires. Wiring splices are made by joining the bare metal ends of wires together. 10 to 15 a great many electrical projects require you to join splice circuit cables together. Proper joint of electric wire.

When splicing insulated wire you have to strip the insulation from the end of the wire to expose the metal core which may be solid or stranded copper. If possible you should twist the wires in line before soldering as this makes a stronger and neater join than twisting the ends together. Twisting the wires together and soldering is often the best method but there are two ways of doing this. The third part is a nut that screws over that and compresses the rubber part between the two metal parts in order to form a watertight seal.

Bus bar screw terminals with these types of terminals each cable core has its own location hole and screw for securing to a terminal. These typically are a special design used to connect an aluminum and copper wire together so that a short copper jumper or pigtail may be connected to a cu rated terminal. With the exception of stranded wire which we ll talk about below it s important to make sure the ends of all wires are lined up before twisting on the wire nut connector. Sometimes this occurs at fixture boxes but it also can occur wherever you want to branch a circuit into two or more directions.
