  1. Materials

  1. Read and translate the text.


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.

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


  1. 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

  1. 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.

Electrical safety

Although electricity is a part of everyday life, it still has many hazards. Following a few simple safety rules can save your life.

Electricity shocks people when their bodies become part of an electrical path between

  • A live wire and the ground

or

  • Two live wires with opposite charges

Being shocked can cause serious burns. It can also paralyze muscles.

Electrocution is also a major risk when working with electricity.

To reduce electrical safety hazards always

  • De-energize power sources before working with electrical equipment

  • Follow lockout/ tagout procedures

Remember: all electricity, including static electricity, can be dangerous. Never take risks.

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.

other.

2. Which of the following is NOT true according to the article?

A Armored cable is a newer kind of wire.

B NM cable is found in newer buildings.

C Wires are unsafe in old buildings

D SE cable is not used underground.

  1. Wire Codes

  1. Read and translate the text.

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.


  1. Read the cheat sheet about wiring codes. Then, choose the correct answers.

1. What is the purpose of the cheat sheet?

A to help electricians choose the right wires

B to explain why wiring codes are complicated

C to give advice about the best kind of wire

B Certain wires are used for specific locations.

C Wires are marked on the protective casing.

D Wires are rated depending on thickness.

3. What should electricians do before installing a wire?

A find a good location

B read the wire's heat marking

C determine the wire gauge

D inspect the water resistant marking
