1. The document provides instructions for splicing electrical wires, which involves removing damaged sections of wire and connecting the cut ends. 2. Key steps include stripping insulation from cut wire ends, twisting the bare wire strands together, applying solder to coat the twisted wires, and insulating the spliced connection with heat shrink tubing or electrical tape. 3. Proper splicing restores electrical continuity safely by joining wire ends in a way that prevents short-circuiting and protects the connection from external damage or shorting over time.

Wires

• Steps
• 1. Locate the damaged area of the wire.The metal conductor of the wire is
covered with a plastic insulation coating that should appear smooth. A
crack, kink or burn spot on the insulation will be visible at the site of the wire
damage

3. 2. Clear the damaged area. Use a standard wire stripping tool to cut the wire
on either side of the damaged area. Evaluate the spacing of the cuts.The cuts
should be far enough from the damaged area so that the damaged wire is all
removed, but as close to the damaged area as possible to avoid cutting away
undamaged wire. If the cuts are too wide apart, the wire may not be long
enough to make the required connection.

4. 3.Discard the damaged area of the wire.

5. 4. Remove insulation from the 2 newly created ends of the wires. Remove
about 1 inch (2.5 cm) of insulation from each wire end.Choose the appropriate
wire stripping opening on a standard wire stripping tool. A standard wire
stripping tool will have multiple stripping openings.The corresponding wire
size to be stripped will be marked on the tool.
Choose an opening cutting for an unknown wire size. If you are not certain of
the wire size, pick a cutting opening that will cut fully through the insulation.
Ensure that the inner opening is big enough to allow the metal conductor
inside the insulation to pass through the cutting operation without being
damaged.
Pull the stripping tool down the wire. Affix the tool about 1 inch (2.5 cm) from
the end of the wire. Hold the tool firmly shut while pulling it down the length
of the wire.

7. 5. Form the wires. If the wire is made up of many
smaller strands twisted together, gently maneuver
the strands so they are all laying to form a smooth
cylinder. If the wire is a solid conductor wire, this will
not be necessary.

8. 6. Place heat shrink tubing.To use heat shrink tubing to
insulate the splice, cut off a piece of tubing about twice as
long as the area of the splice. Slide it on to the end of
either of the wires. Push it up the wire out of the way of
the splice so that it is not prematurely heated by the
splicing operation.

9. 7. Connect the wires by twisting. Carefully twist the wires
so that they remain in line with the rest of the wires, rather
than bending up at an angle at the twist joint.The twist
joint should have the wires snaking around each other in a
line that continues the line of the original wire.

10. 8. Prime the soldering iron. Place a small amount
of solder on the end of the tip of a heated soldering
iron. It will become a viscous liquid.

11. •9. Solder the wires. Gently press the primed tip of the
soldering iron on the center of the twisted wires.The
wires will heat enough to melt solder.Apply solder slowly
to the wires. Apply enough solder to evenly coat the
exposed wire surfaces. Do not get so much solder on the
wires that it becomes a mass or ball and prevents you
from seeing the wires.
Set the solder joint. Remove the soldering iron from the
wires. Keep the wires still until the solder re-solidifies.
The solder will dull slightly in shine as this occurs.The
solder should set within ten seconds.

13. 10. Insulate the splice.Set heat shrink tubing. If you used heat
shrink tubing to insulate the splice, slide it down over the splice.
Using a heat gun, heat the tubing so that it shrinks to fit snugly
over the splice. Do not overheat it or the tubing will crack and char.
Wrap the splice in tape. If you did not use heat shrink tubing, cover
the splice completely with a helical wrapping of electrical tape

14. EXTENSION CORD
• An extension cord is a span of flexible electrical power cable with a plug on
one end and multiple sockets on the other end. It comes in several varieties
to suit the needs of the user.
• The best remedy to address the insufficiency of available outlet is to use an
extension cord especially if the electrical gadgets need to operate at the
same time.
