Choosing the right drill for the job
Most jobs can be done using a simple rotary
drill. It can be used for wood and plywood. It can also be used for drywall,
plaster, copper and steel. Of course, you need to have the right
drill bits too.
What about for harder materials like brick
and concrete? A hammer drill works well for blocks, brick,
mortar and stone. A rotary hammer works best for materials
like concrete and cement.
Sometimes the terms hammer drill and
rotary hammer are used to mean the same tool. However, a hammer drill chips
away at the material. A rotary hammer pounds away at it to make a hole.
Exercises
1. Before you read
the passage, talk about these questions.
1. What are some materials electricians work
with on the job?
2. What are some tools electricians might

Electrician
Occupations
Outlook
The job of an electrician involves putting
in and maintaining electrical power systems. This is done in homes and
businesses.
The work of an electrician is occasionally
demanding. Electricians must lift heavy objects and climb
ladders.
The work may require them to bend, stand,
kneel, or stoop down low for long periods.
To be successful, electricians need to
work fast. In order to grab and release tools quickly, they wear
a tool belt. To prevent electric shook, electricians usually turn off the
power source before working. They turn on the power when they are done.
Electricians also use sharp tools to split wires.
Exercises

Fixing Underground Wires
Fixing underground wires sounds
difficult. But it’s actually simple. You just need to splice some
wires.
To begin, switch
off the electricity. Accidental shocks are always a risk
when working with electricity. Next, test
the electricity to make sure it is off. Push a button
on the same circuit. If it is safe, dig
into the ground. Inspect the wires, and
find the damaged part. Cut it off. Next, strip the insulation off the
wires. Twist the ends of the wires
together. Then, pull on them to make sure they are joined.
If they are, bind the ends together with
tape. After that, install I waterproof insulation
plastic covering on the wires. Then connect the electricity.
Exercises
2. Read
the instructions for fixing underground wires. Then, choose the correct
answers.
1. What are the instructions mostly about?
A why it is important to replace wires
B how to fix a damaged wire
C what insulation is made out of
D how to inspect an electric circuit
2. Why should the electricity be switched off?
A to make sure the wires aren't damaged
B to avoid getting shocked by the wires
C to make it easier to find the wires
D to check that the wires are connected
3. What is the last step in the instructions?
A strip the insulation from the wires
B inspect the underground wires
C install waterproof insulation
D turn on the electricity again
3.

10. Measurements
1. Read and translate the text.
Know Your
Measurements
Fasteners and tools use imperial
measurements or metric, and knowing the difference is important. It
prevents you from rounding off a fastener, damaging tools, or
causing injury. If you don’t know an item’s size, use a micrometer or
other caliper to measure it. Check centimeters or millimeters
for metric tools. Look at inches for imperial tools.
You will also need to know larger
measurements, such as feet, yards, and meters. These
measurements are often used in building plans.
Temperature measurements are also
important to know. Some countries measure degress using the Fahrenheit
scale and others use the Celsius scale. You may need to convert
from one scale to the other.

13. Types of Wires
1. Read and translate
the text.
There are many different types of
electrical wire and cable. Knob and tube (K& T) wiring is one of the
oldest types of wiring. Older types of cable are armored cable (AC) and metal-clad
(MC) cable. Both of these are insulated by steel. These were replaced
in newer construction by nonmetallic (NM) sheath cable. However,
replacement is not required if the wire or cable jacket is still good.
Check them to make sure there is no bare conductor or wire showing. Underground
feeder (UF) cable and service entrance (SE) cable are used outdoors.
However, SE cable is only approved for above-ground use.

Reading Wire Codes
Wiring
codes are complicated. Here are some tips to make your job simpler.
1.Before
installing any wire, read the gauge. Each wire has a number embossed
on its sheath. The number refers to the diameter of the wire.
2.Know
the rating for wire gauges. Wires with larger numbers are lesser in
diameter. So, zero, or ought gauge wire has a bigger diameter than a 14
gauge.
3.
Remember that different kinds of wires go in different locations. An ‘H’
on a wire means the maximum amount of heat it can stand is 165
Fahrenheit. A ‘W’ means you can put it in a damp area. It is water resistant.
