Rat Tail or Pig Tail. This kind of joint is commonly used to join two or more conductors inside the junction box. It is suitable for service where there is no mechanical stress when wires are to be connected in an outlet box, switch, or conduit fitting.



Western Union Short-tie Splice. This is the



Aerial tap. This is used as a temporary tap usually done in constructions sites. The easy twist will facilitate tap wire movement.



done as in plain tap and the only difference is that this tap is a combination of two plain taps place side by side with each other.



This is used on large solid conductors where it is difficult to wrap the heavy tap wire around the main wire.



Plain tap joint. This is used where the tap wire is under considerable tensile stress circuit.



most widely used splice or joint in interior wiring installation to extend the length of wire from one point to another.



Double Cross joint. The same application is



Wrapped Tap or Tee Joint.



Hook. This is a kind of splice that has a rounded head and is use to hung the wire.



Knotted tap. This is



Y-splice. This method of wrapping is



used where the tap wire is under heavy tensile stress.



generally used on small cables because the strands are flexible and all can be wrapped in one operation.



Duplex cross joint. This is a



Octopus Joint. It has a four



two-tap wire turned simultaneously and is used where the two tap wire is under heavy tensile stress.



wire thatthat combined together to hold each other tightly.



Western Union Long Tie. This is used extensively for outside wiring to extend the length of wire from one end to another.



Duplex joint. This is a used where twin wire is employed. that is two-wire cables.it consist of two bell hanger’s joint spaced so that they do not come opposite eacher. erotheer



Split tap splice This is used for large wire (14mm2 and larger) because it is easier to wrapped a single wire at a turn than to wrapped them all at once.



Single Wrapped Splice. This is used for large wire (14mm2 and larger) because it is easier to wrapped a single wire at a turn than to wrapped them all at once. is used



Running Butt Splice This is formed by butting together the end of two cable lengths to extend the run or length of circuit. And classified as single wrapped splice and multi wrapped splice.



Turn Back Joint This is used to connect two continuous run conductor under extreme tension.



Tap Splices. This are made when the end of one stranded conductors is to be connected at some point along the run of another stranded conductors. they are classified as ordinary split and y-splice.
