Learning activities:
1.1.1 Principles of knob and tube
PRINCIPLES OF KNOB AND TUBE
The open or exposed wiring method is sometimes referred to as the Open

Wiring on Insulators. (PEC section 212) It uses cleats, knobs (split or solid),
porcelain tubes and mica tubing for the support and protection of insulated
conductors run in or on buildings. It may be used for exposed work, either outside
or inside building in dry or wet locations. It shall not be used however, in the
following:
1. Commercial Garages
2. Theaters
3. Motion Picture Studious
4. Hoist ways
5. Hazardous Location
In the open or exposed wiring method, the wires are visible and are
supported by the knobs. These knobs may be the split or solid type. This is shown
in figure 1.
Figure 1. The Split and Solid knobs
Code No. Date: Developed Date: Revised Page #

Module Name
Unit of Competency Doc created date Doc modified date 1
Split knobs are used to support wires smaller than No. 8. Solid knobs are used
to support or anchor wires as big as No. 8 or bigger. Screws or nails may be used
to fasten the knobs. When a nail is used a leather washer should be placed
between the nail head and the insulator to form cushion and protect the insulator
from breaking. See figure 2.
Height of Knob
Figure 2. The Solid Knob with Leather washer for Protection
Figure 3. Shows the correct and wrong way of tying wires to the groove of a solid
knob with the wires.

Module Name
In installing an electrical wiring system with the exposed knob and tube wiring
method, the distance between conductors should be maintained at a minimum
distance of 6 cm. (2 ½ inches) apart. The knobs should also spaced 30 cm (1 feet)
apart. Figure 4 illustrates this provision of PEC.
30 cm. 1
Ft.
Figure 4. Spacing of Split Knobs and Conductors
Whenever wires pass through studs, rafters, floor joists or any wooden part
of a building, the wires are inserted in porcelain tubes or flexible mica tubing.
Porcelain tubes and mica tubing are also provided whenever wires cross each
other. It gives the wire extra protection from injury.

Module Name
Figure 5. Application of Porcelain Tubes and Mica Tubing
Some advantages of the Knob and Tube wiring:
1. It is used in temporary installation, such as construction jobs.
2. It has economical when properly installed.
3. It has a lower operating temperature because of ventilating hence, the

higher current carrying capacity of the wire.

Module Name
Safety reminders when installing knob and tube wiring
1. Apply enough pressure on the gimlet when driving it to the word board.
Never hammer it.
2. Have the auger brace oiled regularly especially the ratchet type.
3. Have your electrician’s knife sharpened enough in order not to nick the wire.
4. Use the right-sized screw driver for the right size of screw.
5. Be sure that the conductors in contact with the wiring surface are enclosed
in mica tubing.
6. Be sure your teacher has checked your work before testing.
7. Be sure the safety switch is off before making any connection. Apply tape on
all joints/splices.
8. Do not drive the split-knobs completely before the conductors or wires are
run/inserted along the grooves of the knobs.
9. Be sure to test the insulation for short and ground circuit before putting on
the power.

2.1.1 Identify Rigid Non- Metallic Conduit (PVC)
Rigid Non-Metallic Conduit (PVC)
Non-metallic conduits are electrical materials which are manufactured to be

resistant to moisture and chemical atmosphere. They are also manufactured to be
flame retardant or not easily burned. They are resistant to impact and crushing,
they do not easily get out shape because of heat. These conduits are classified
according to the materials they are made of. The most common ones are asbestos
cement conduit, polyvinyl chloride, conduit and high density polyethylene conduit.
The Philippine Electrical Code provides that rigid non-metallic conduit may
be used under the following conditions:
1. Concealed in floors, walls and ceilings
2. Direct earth burial or underground

 600 mm under streets, highways, roads, alleys, driveway and parking
lots
 460 mm under driveways and parking lots of single and two family
dwelling units
 460 mm under airport runways, including adjacent areas where
trespassing is prohibited
3. In locations subject to severe corrosive influences
4. and where subject chemicals for which the materials are specifically
approved
5. Cinder fill
6. In wet locations, provided water is prevented from entering the conduit
7. In dry and damp locations
The Philippine Electrical Code prohibits the use of rigid non-metallic conduit
under the following conditions:
1. Hazardous (Classified) locations
2. Support of fixtures
3. Physical Damage – Where subject to physical damage unless identified for
such use.

Different types of Surface Raceway
Identifying Different Types of Bend
The PVC or polyvinyl chloride rigid conduit is one of the most commonly
used conduits in electrical wiring installation today. Its preparation for installation
is much easier than the metallic rigid conduit. In preparing a non-metallic rigid
conduit for installation, an electrician needs to do cutting, heating and bending.
Like in metallic rigid conduit offset bends, 90o angle bends and other bends are
also made on PVC rigid conduit. In making bends on PVC rigid conduit, the
electrician should see to it that the internal diameter of the conduit is not reduced
and damaged so that the capacity of the conduit to accommodate maximum
number of conductors will not be lessen and to facilitate easy pulling of
conductors.
Since PVC conduits are somewhat easier to bend than a rigid conduit, it
likewise requires patience as in any other type of conduit. It is first pre-heated
over a fire or a heat gun to a desired softness. Little by little, it is bent to its
desired shape. When such is attained, it is then hardened by soaking it to cold or
lukewarm water or dampened with a wet rag.

1. Elbow
2. Offset bend is less than 90o

bend, it is used when the
conduit crosses an obstacle
or when the conduit is
entering an electrical box.
3. Round saddle bend is used

when the conduit run across
circular objects like pipes.
4. Square saddle bend is

similar to round saddle, it is
used when the conduit run
across rectangular obstacles.
Square saddle is just a
combination of two offset Obstacl

Fluorescent Lamp –is a form of electric discharge light source. It consists of a

glass tube containing mercury vapor at a low pressure and inert gas like argon
and krypton. The interior is coated with phosphor, which glows or fluoresces when
exposed to ultraviolet light.
Kinds/types of electric discharge lamps
1. Pre-heat starting, hot-cathode – requires starter (glow switch) and is pre-

heated during starting. It uses a ballast to produce high voltage to start the
lamp into operation and to limit the flow of current.
2. Cold cathode – requires high voltage in its operation. This lamp has
electrodes made of thimble-type iron. It is not pre-heated and does not require
a starter for starting. Special high voltage transformers operate it. Neon and
mercury lamps are classified under cold cathode lamps.
3. Instant-starting, hot-cathode – the lamp cathode in the instant-start is not

pre-heated. Sufficient voltage is applied across the cathodes to create an
instantaneous arc. As in preheat circuit; the cathodes are heated during lamp
operation by the arc. The instant-start lamp require single-pin bases, are
generally called slim line lamps.

Module Name
4. Hot-cathode, rapid-start – these are similar in construction to the preheat

lamps; the basic difference is in the circuitry. This circuit eliminates the delay
inherent in preheat circuits by keeping the lamp cathodes constantly energized
(preheated). When the lamp circuit is energized, the arc is struck immediately.
No external starter is required. Because of this similarity of operation, rapid
start lamps will operate satisfactorily in a preheat circuit. The reverse is not
true, because the preheat requires more current to heat the cathode than the
rapid-start ballast provides.
Operation of pre-heat type fluorescent lamp
The tube filaments, starter (glow switch), and ballast are all connected in series, which
constitute a complete circuit once the switch, is closed. As a current flow through, the gas
(inert) inside the starter glows and the electrodes are heated. Since one of the electrodes is
a bi-metal, it bends and makes contact with the other. At this instant, the circuit is
metallically complete. The filaments of the fluorescent tube are then heated and partial
ionization takes place. The bi-metals in the starter cools and the contacts open. The
magnetic field in the ballast collapses rapidly producing an inductive kick, which
establishes a current between the filaments and fires the tube into operation.

Current moves in utilizing the rare gas as conducting means and the rare
gas produces a “GLOW”. The glow generates heat and causes the bimetallic blade
to expand.
When the bimetallic blade is heated, it changes shape and touches the fixed
contact. The close contacts of the two starter contacts produce an easy path for
current flow.

Terminal block
In common with all gaseous discharge lamps, the fluorescent must be provided
with some device for limiting the current drawn by the discharge. Without a
limiting device, the current would rise to a value that would destroy the lamp. A
device or auxiliary called ballast can best meet this requirement.
The ballast for operating lamps on an alternating current consists of a small

choke coil woven on an iron core.

Module Name
This ballast serves three important functions:
1. It preheats the electrodes to make available a large supply of the electron.

2. It provides a surge of relatively large potential to start the arc between
the electrodes.
3. It prevents the arc current to increase beyond the limit set for each size
and lamp.
THE LIFE SPAN OF FLUORESCENT LAMP
The life of fluorescent lamp is affected not only in the fluctuation of voltage
and current but also by the number of times it is started. Electron emission
material is “sputtered off” from the electrodes continuously during the operation of
the lamp and in larger quantities each time the lamp starts.
Many fluorescent lamps have a rated average life span up to 30,000

continuous burning hours but with an average of 3 hours burning per start, it
could only last for 12,000 hours.

7.1 Layout and Install Incandescent Lamp
7.1.1 Identify the history and development of an Incandescent Lamp
History and development of incandescent lamp
THE INCANDESCENT LIGHT BULB
The first incandescent electric light was made in 1800 by Humphry Davy,
an English scientist. He experimented with electricity and invented an electric
battery. When he connected wires to his battery and a piece of carbon, the carbon
glowed, producing light. This is called an electric arc.
Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-
1914) was determined to devise a practical, long-lasting electric light. He found
that a carbon paper filament worked well, but burned up quickly. In 1878, he
demonstrated his new electric lamps in Newcastle, England.
The inventor Thomas Alba Edison (in the USA) experimented with
thousands of different filaments to find just the right materials to glow well and be
long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free
bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb
that could glow for over 1500 hours.
Lewis Howard Latimer (1848-1928) improved the light bulb by inventing a

carbon filament (patented in 1881); Latimer was a member of Edison's research
team, which was called "Edison's Pioneers." In 1882, Latimer developed and
patented a method of manufacturing his carbon filaments.
In 1903, Willis R. Whitney invented a treatment for the filament so that it

would not darken the inside of the bulb as it glowed. In 1910, William David
Coolidge (1873-1975) invented a tungsten filament, which lasted even longer than
the older filaments. The incandescent bulb revolutionized the world.

Edison’s first successful lamp
It is certainly true that Edison did invent the light

bulb (or at least "a" light bulb), but he was not the first. In
1860, an English physicist and electrician, Sir Joseph
Wilson Swan, produced his first experimental light bulb
using carbonized paper as a filament. Unfortunately, Swan
did not have a strong enough vacuum or sufficiently
powerful batteries and his prototype did not achieve
complete incandescence, so he turned his attentions to
other pursuits.
So it is reasonable to wonder why Edison received all of the credit, while

Swan was condemned to obscurity. The more cynical among us may suggest that
Edison was thrust into the limelight (see note below) because many among us
learn their history through films, and the vast majority of early films were made in
America by patriotic Americans.
However, none of this should detract from Edison who, working

independently, experimented with thousands of filament materials and expended
tremendous amounts of effort before discovering carbonized thread. It is also
probably fair to say that Edison did produce the first commercially viable light
bulb.
The reason why this is of interest to us here is that Edison's experiments

with light bulbs led him to discover the Edison Effect, which ultimately led to the
invention of the vacuum tube
As one final nugget of trivia, the term "limelight" comes from the
incandescent light produced by a rod of lime bathed in a flame of oxygen and
hydrogen. At the time it was invented, limelight was the brightest source of
artificial light known. One of its first uses was for lighting theater stages, and
actors and actresses were keen to position themselves "in the limelight" so as to be
seen to their best effect.
Furthermore, in 1880, Swan gave the world's first large-scale public

exhibition of electric lamps at Newcastle, England.
Edison's light bulbs employed a conducting filament mounted in a glass

bulb from which the air was evacuated leaving a vacuum. Passing electricity
through the filament caused it to heat up enough to become incandescent and
radiate light, while the vacuum prevented the filament from oxidizing and burning
up.

Operation of incandescent lamp
What makes a light bulb glow?
The thin wire, or filament, inside a light bulb resists the flow of current through it.
When electricity is passed through the bulb, the filament becomes hot and glows brightly.
To prevent the filament burning away completely, the glass bulb filled with a mixture of
inert gas (usually argon and nitrogen). The filament in most light bulbs is made of
tungsten.

Classification of Incandescent Lamp
1. Large lamps –are those normally used for interior and exterior general and
task lighting. (See figure next page)
1. Miniature lamps –are generally used in automotive, aircraft, and appliance

applications.
3. Photographic lamps –as the name implies, are used in photography and
projection service.

Kinds of High Intensity discharge lamp
1. Mercury lamp –is an electric discharge lamp in which the major portion of
the radiation is produced by the excitation of mercury atoms.
2. Metal halide lamp –is an electric discharge lamp in which the light is
produced by the radiation from an excited mixture of a metallic vapor
(mercury) and the products of the dissociation of halides (for example,
halides of thallium, indium, sodium).

2. High-pressure sodium lamp –is an electric discharge lamp in which the

radiation is produced by an excitation of sodium vapor in which the partial
pressure of the vapor during operation is of the order of 104 N/m2.
The Incandescent Filament Lamp
Construction
This lamp consist simply of a tungsten filament inside a gas-filled, sealed

glass envelop. Current passing through the high-resistance filament heats it to
incandescence, producing light. Gradual evaporation of the filament causes the
familiar blackening of the bulbs and eventual filament rupture and lamp failure.
