COMMON WIRE SPLICES AND JOINTS

Question 1

• This kind of joint is commonly used to join two or more conductors inside the junction box.

Answer 1

RAT TAIL OR PIG TAIL

Question 2

• This method of wrapping is generally used on small cables because the strands are flexible.

Answer 2

Y-SPLICE

Question 3

• Used where the tapware is under heavy tensile stress.

Answer 3

KNOTTED TAP

Question 4

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

Answer 4

PLAIN TAP JOINT

Question 5

• Used as a temporary tap usually done in constructions sites.

Answer 5

AERIAL TAP

Question 6

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

Answer 6

DUPLEX CROSS JOINT

Question 7

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

Answer 7

WESTERN UNION SHORT TIE SPLICE

Question 8

• Used extensively for outside wiring extend the length of wire from one end to another.

Answer 8

WESTERN UNION LONG TIE

Question 9

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

Answer 9

CROSS JOINT

Question 10

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

Answer 10

WRAPPED TAP OR TEE JOINT
