1. JOINTS IN ELECTRICAL CONDUCTORS
Sarvagna Skill Development Centre
Bangalore.
Pig-tail/rat-tail/twisted joint

2. Used in a junction box and for connecting branch circuits. joint is
suitable for pieces where there is no mechanical stress on the
conductors

3. Married Joint
The married joint is an electrical joint used for
joining multi-strand cables. A married joint is
used where electrical conductivity is required,
along with compactness.

4. Tee Joint
This joint could be used in overhead
distribution lines where the electrical
energy is to be tapped for service
connections

5. Britannia Straight Joint
This joint is used in overhead lines where considerable
tensile strength is required. It is also used both for
inside and outside wiring where single conductors of
diameter 4 mm or more are used

6. Britannia Tee Joint
This joint is used for overhead lines for tapping the
electrical energy perpendicular to the service lines.

7. Western union joint
This joint is used in overhead lines for extending the length of wire
where the joint is subjected to considerable tensile stress.

8. Scarfed Joint
This joint is used in large single
conductors where good appearance and
compactness required and there is no
strain on the wire.

9. Plain tap Joint
This joint is the most frequently used, and
is quickly made.

10. Aerial tap Joint
This is used as a temporary tap usually done in
construction sites. This joint is suitable for low
current circuits only.

11. Knotted tap Joint
A knotted tap joint is designed to
take considerable tensile stress

12. Duplex-cross tap Joint
It is used where two tap conductors need to
extend away from the branch conductor in
the opposite direction.

13. Double-cross tap Joint
This joint is used where two wires are to be tapped
at the same time
