What is a rat-tail splice?
A rat-tail splice, also known as a twist splice or a pig-tail splice, is a very 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 other means.

How To Splice A Wire?
The first one is stripping wires prior to splicing, while the second one is splicing with the help of a twist-on wire cap that is often called "a wire nut." Follow these basic steps to perform splicing. As a rule, all manipulations should be performed within a junction box.
What is mechanical splicing?
Mechanical splicing is the technique that allows joining fiber optic cables manually using only tools without a special electrical device. The fibers are connected using a special index matching liquid. The mechanical splice that connects the fibers is usually about 6 cm long. A covering is used to speed up the splicing process.
How does fusion splicing work?
During fusion splicing, a special kind of fusion splicer machine is used to connect the two fibers. The ends are attached using electrical heat by creating an electrical arc. Thanks to the use of the machine, the connection between the two fibers is transparent and non reflective. Do mind that fusion splicing is more pricey than the mechanical one; however, it is considered higher quality and gives a longer life to the spliced cables. With fusion splicing, there is less reduction of the electrical current and less transmission loss. Fusion splicing is typically performed by a skilled technician. The typical loss of light transmission during the fusion splicing is around 0.1 dB, and the insertion loss is even less than this.

What happens if you don't splice electrical wires correctly?
Splicing electrical wires - that is, the electrical connection or joining of two or more wires that conduct electricity in a building - is a task that can be learned easily, but if the splice is not made correctly, the electrical system will be unreliable and unsafe, risking fire or shock hazards.
How to strip bare wire?
For intermediate-sized electrical wires such as #14 copper wire (a 15-Amp electrical circuit) or #12 copper wire (a 20-Amp electrical circuit), you can usually strip about 3/4" of bare wire (special stripping tools are available that won't damage the wire or you can work carefully with wire cutters or a knife), and you can twist your wires together (clockwise) by holding the wires in one hand and twisting the bare ends using a single pair of pliers.
How to prevent wire twisting?
The way to prevent this is to make certain the twist is started with all the wires bent at approximately a right angle. (Don't bend current-conducting electrical wires at a sharp angle however.) Then if the bent wires are interlocked and held with pliers, the twist will continue as started.
