Electrical wire or
conductor could be:
insulation.
a. Stranded wire Is made of multiple strands of copper or
aluminum joined together to make a
single wire.
b. Solid wire
Is made of a single strand of copper or
aluminum wire. These are used in wiring
installation inside and outside the
buildings.
Conduits/Pipes
Are tubes that are used not only to
protect wires but also to route electrical
wiring throughout a building.
Common Types of
Conduits/Pipes
a. Rigid Steel Conduit
(RSC)
Is a thick-walled threaded tubing, usually
made of hot-dipped galvanized inside
and outside and is threaded at both
ends.
b. Flexible Non-
metallic conduit or
corrugated plastic
conduit (CPC)
Is flexible corrugated plastic tubing that
is moisture-resistant and flame-
retardant. It is easy to bend and installs
with snap-lock or glued plastic fittings.

and anchor electrical conduits to its
proper position.
Connectors
Are used to attach metallic or non-
metallic conduit to the junction or utility
boxes.
COMMON WIRE SPLICES AND JOINTS
Introduction:
As a student in Electrical Installation and Maintenance, you should acquire the
important knowledge and skills in wire splices and joints and be familiar with the actual
application of every splice and joint. This will serve as your tool in performing actual
wiring installation.
15
The following are common electrical wire splices and joints.
Rat Tail or Pig Tail. This kind of joint is
commonly used to join two or more
conductors inside the junction box. It is
suitable for service where there is no
mechanical stress when wires are to be
connected in an outlet box, switch, or
conduit fitting.
Y-splice. This method of wrapping is
generally used on small cables because
the strands are flexible and can all be
wrapped in one operation.
Knotted tap. This is used where the tap
wire is under heavy tensile stress.
Plain tap joint. This is used where the
tap wire is under considerable tensile
stress circuit.
Aerial tap. This is used as a temporary
tap usually done in constructions sites.
The
easy twist will facilitate tap wire movement
16
Duplex cross joint. This is a two-tap wire
turned simultaneously and is used where
the two tap wire is under heavy tensile
stress.
Western Union Short-tie Splice. This is
the most widely used splice or joint in
interior wiring installation to extend the
length of wire from one point to another
Western Union Long Tie. This is used
extensively for outside wiring to extend
the length of wire from one end to
another.
Cross joint. The same application is done
as in plain tap but the only difference is
that this tap is a combination of two plain
taps placed side by side with each other.
Wrapped Tap or Tee Joint. This is
used on large solid conductors where it
is difficult to wrap the heavy tap wire
around the main wire.
17
EXTENSION CORD/WIRE
An extension cord is an extension of which power is drawn. It has a
male plug on one end and a surface type convenience outlet on the other end.
One of the most important considerations is the power handling capacity to
make it safe and functional. The best remedy to address the insufficiency of
available outlets is to use an extension cord or wire. We should be very
careful in inserting electrical tools or equipment in the extension cord because
the rated current of the inserted equipment or tools should not to exceed the
allowable ampacity of the flat cord.
Below is an image of an extension cord

COMMON ELECTRICAL MATERIALS Electrical materials are developed and constructed for a special purpose, such as to: 1. control the flow of current in an electrical circuit; 2. carry electrical current from the source to the load or current consuming apparatus; 3. hold and secure wires to its fixtures inside and outside houses and buildings; and 4. protect houses, buildings, appliances, and instruments from destruction and damage. The following are the most commonly used electrical materials. Materials Description Picture Convenience outlet Is a device that acts as a convenient source of electrical energy for current consuming appliances. It is where the male plug of an appliance is inserted and is usually fastened on the wall or connected in an extension cord. It may be single, duplex, triplex, or multiplex and could be surface type or flush type.
  • 19. 11 Common Types of Convenience Outlet a. Surface type This type of outlet is typically mounted on the surface portion of the wall. Three Gang Surface Type b. Flush type This type of outlet is typically buried in concrete and is attach to the utility box Male plug Is a device inserted to a convenience outlet to allow the flow of electric current. This is use in making extension wires. Lamp holders These are devices that hold the lamp and are also called Lamp Sockets or Ceiling Receptacles. These come in many designs and sizes. They are classified as flush, hanging (weather proof/chain), and surface types. Switch Is a device that connects and disconnects the flow of electric current in a circuit. There are many shapes, designs, and types and they are classified as hanging, flush, and surface types. Fuse Is a circuit protective device that automatically blows and cuts the current when overload or short circuit happens.
  • 20. 12 Circuit Breaker Is a protective device that automatically trips and cut the current when trouble in the circuit such as short circuit or overload occurs. It comes in 2 poles, 3 poles and 4 poles. Junction Box Is an octagonal shaped electrical material where connections, joints or termination of wires are being done. It is also where the flush type lamp holder is attached. This could be made of metal or plastic (PVC) Polyvinylchloride. Utility Box . Is a rectangular shaped metallic or plastic (PVC) material in which flush type convenience outlet and switch are attached. Flat Cord Is a duplex stranded wire used for temporary wiring installation and commonly used in extension cord assembly. It comes in a roll of 150 meters and sizes of gauge # 18, gauge # 16 AWG and gauge # 14 AWG (American wire gauge). Electrical Wire/Conductor Is the means in which electrical current will flow. It is usually made of copper or aluminum with or without outside
  • 21. 13 Electrical wire or conductor could be: insulation. a. Stranded wire Is made of multiple strands of copper or aluminum joined together to make a single wire. b. Solid wire Is made of a single strand of copper or aluminum wire. These are used in wiring installation inside and outside the buildings. Conduits/Pipes Are tubes that are used not only to protect wires but also to route electrical wiring throughout a building. Common Types of Conduits/Pipes a. Rigid Steel Conduit (RSC) Is a thick-walled threaded tubing, usually made of hot-dipped galvanized inside and outside and is threaded at both ends. b. Flexible Non- metallic conduit or corrugated plastic conduit (CPC) Is flexible corrugated plastic tubing that is moisture-resistant and flame- retardant. It is easy to bend and installs with snap-lock or glued plastic fittings. c. Rigid Non-metallic conduit (PVC) Is similar to plastic plumbing pipe and installs with fittings. It can be bent after being heated using portable heat gun.
  • 22. 14 d. Electrical Metallic Tubing (EMT) Are made of electro-galvanized metal. It is typically thin and lightweight. EMT is rigid but can be bent with a simple tool called a conduit bender. e. Flexible Metal Conduit (FMC) Has a spiral construction that makes it flexible so it can snake through walls and other structures. f. Liquid tight Flexible Metal Conduit (LFMC) Is a special type of flexible metal conduit that has a plastic coating and is used with sealed fittings to make it water tight. Clamps Electrical materials are used to hold and anchor electrical conduits to its proper position. Connectors Are used to attach metallic or non- metallic conduit to the junction or utility boxes. COMMON WIRE SPLICES AND JOINTS Introduction: As a student in Electrical Installation and Maintenance, you should acquire the important knowledge and skills in wire splices and joints and be familiar with the actual application of every splice and joint. This will serve as your tool in performing actual wiring installation.
  • 23. 15 The following are common electrical wire splices and joints. Rat Tail or Pig Tail. This kind of joint is commonly used to join two or more conductors inside the junction box. It is suitable for service where there is no mechanical stress when wires are to be connected in an outlet box, switch, or conduit fitting. Y-splice. This method of wrapping is generally used on small cables because the strands are flexible and can all be wrapped in one operation. Knotted tap. This is used where the tap wire is under heavy tensile stress. Plain tap joint. This is used where the tap wire is under considerable tensile stress circuit. Aerial tap. This is used as a temporary tap usually done in constructions sites. The easy twist will facilitate tap wire movement
  • 24. 16 Duplex cross joint. This is a two-tap wire turned simultaneously and is used where the two tap wire is under heavy tensile stress. Western Union Short-tie Splice. This is the most widely used splice or joint in interior wiring installation to extend the length of wire from one point to another Western Union Long Tie. This is used extensively for outside wiring to extend the length of wire from one end to another. Cross joint. The same application is done as in plain tap but the only difference is that this tap is a combination of two plain taps placed side by side with each other. Wrapped Tap or Tee Joint. This is used on large solid conductors where it is difficult to wrap the heavy tap wire around the main wire.
  • 25. 17 EXTENSION CORD/WIRE An extension cord is an extension of which power is drawn. It has a male plug on one end and a surface type convenience outlet on the other end. One of the most important considerations is the power handling capacity to make it safe and functional. The best remedy to address the insufficiency of available outlets is to use an extension cord or wire. We should be very careful in inserting electrical tools or equipment in the extension cord because the rated current of the inserted equipment or tools should not to exceed the allowable ampacity of the flat cord.
