C. MOTIVATION
Matching Type
1. Are you familiar with what you have seen in the pictures?
D. Lesson Proper
A splice joint is a method of joining two members end to end in woodworking.
The splice is used when the material being joined is not available in the length required.
It is an alternative to other joints such as the butt joint and the scarf joint.
Types of Common Wire Splices and Joints
1. Rat Tail or Pig Tail
This kind of joints is commonly used to join two or more conductors
inside the junction box.
2. Aerial Tap
This is used as a temporary tap usually done in construction site.
3. Plain Tap Joint
This is used where the tap wire under considerable tensile circuit.
4. Knotted Tap
This is used where the tap wire is under heavy tensile stress.
5. Western Union
Long-tie Splice
This is used extensively for outside wiring to extend the length of wire
from one end to another.
E. Generalization
Splicing and joining wires has a vital role in our daily lives. It is very necessary to
have knowledge in connecting wires. This usually help us in maintaining the safety
when doing splicing and joining wires.
Activity:
The class will be divided into 3 groups.
Each group will perform the proper splicing and joining of wires such as Rat Tail or Pig
Tail, Aerial Tap, Plain Tap Joint, Knotted Tap and Western Union Long-tie Splice.
Each group will use Wires, Long Nose Plier, Plier, Diagonal Plier, Cutter.
The grading system will be based upon the scoring rubrics below.
