To have knowledge and experience on how to Jointing and Splicing a Electrical Wire Gauge. To know the importance on why do we have to Splice an electrical wire gauge.
2. Materials Used:
Electrical Wire Gauge 14
3. Equipment Used:
Long Nose Plier and Cutter
How to Use:
1. Find the right long-nose pliers.
-Long-nose pliers come in different sizes and shapes. Buy quality long-nose pliers that fit your hand and that are suited to the work you'll be doing. The grip varies, as does the length for pliers. Long-nose pliers are commonly 5, 6 or 8 inches long. Decide if rubber-coated handles and serrated teeth are needed for the type of job you'll be working on. 2. Open pliers carefully.
-Use caution when opening long-nose pliers. It's possible to open the pliers too far and get the jaws out of alignment. 3. Get into small areas with long-nose pliers.
-These pliers can be thought of as an extension of your hand. The long nose offers an extended reach and allows work in tight spots that your fingers or hands can't reach. Use the tip of the nose to grip items. 4. Bend or shape wire with long-nose pliers.
-Wire can be bent with long-nose pliers by placing the wire inside the teeth and grasping the wire with your other hand. The pliers act as a vise to hold the wire in one spot while you bend the wire with the other hand. Use the tip of the pliers to shape wire into intricate bends. 5. Cut wire with long-nose pliers.
-Most long-nose pliers come with a cutter that is located under the nose and above the handle. Place wire inside the cutter and close the pliers tightly to sever the wire. 6. Strip protective coating from electrical wire by placing the coated wire inside the teeth.
-Close the pliers until you feel jaws bite the plastic coating then pull the wire through the pliers. This will strip the coating from the wire. Safety Precaution:
1. Pliers should not be used for cutting hardened wire unless specifically manufactured for this purpose. 2. Never expose pliers to excessive heat. This may draw the temper and ruin the tool. 3. Always cut at right angles. Never rock from side to side or bend the wire back and forth against the cutting edges. 4. Don't bend stiff wire with light pliers. Needle nose pliers can be damaged by using the tips to bend too large a wire. Use a sturdier tool. 5. Never use pliers as a hammer nor hammer on the handles. They may crack or break, or edges may be nicked by such abuse. 6. Never extend the length of handles to secure greater leverage. Use a larger pair of pliers or a bolt cutter. 7. Pliers should not be used on nuts or bolts. A wrench will do the job better and with less risk of damage to the fastener. 8. Oil pliers occasionally. A drop of oil at the hinge will lengthen tool life and assure easy operation. 9. Safety glasses or goggles should be worn when cutting wire, etc. to protect eyes.
Electrical splices and joints are places in the continuum of wiring where new wire is added or extended.
The new wire is actually extended to the point where the intended outlet should be. It can also be branched off from other outlets as well.
When conductors are joined together, the connection between them is a splice or a joint. When two conductors are joined end to end, the connection is called a 'straight splice' or a 'straight joint'; when a third conductor is connected at right angles, it is called a 'tee splice' or 'tee joint'.
“Splice” is the preferred name in North America, where tradesmen who specialize in this trade are called 'cable splicers'....
