ELECTRICITY TLE

• Electricity


  The presence of flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best known form is the flow of electrons through conductors such as copper wires.
• Electricity


  When a bunch of atoms are together and electrons are moving from one atom to the other in the same direction, this is called electricity. Electricity is the "flow of electrons". Electricity is both a basic part of nature and one of the most widely used forms of energy.
• Common electrical tools


  • Screwdrivers
  • Hammers
  • Pliers
  • Wire stripper
  • Electrician's knife
  • Portable electric drill
  • Hacksaw
• Screwdrivers


  Tools made of steel hardened and tempered at the tip, used to loosen or tighten screws with slotted heads. They come in various sizes and shapes.
• Types of screwdrivers


  • Standard/Flat screwdriver
  • Philips screwdriver
  • Stubby screwdriver
  • Allen screwdriver/wrench
• Standard/Flat screwdriver


  The blade tip is wedge-shaped and resembles a negative (-) sign. This is used to drive screws with a single slot head.
• Philips screwdriver


  This has a cross tip resembling a positive (+) sign. This is used to drive screws with cross slot heads.
• Stubby screwdriver


  This comes in either Standard or Philips screwdriver with short shank or blade and a shorted handle used to turn screws in tight spaces where a standard screwdriver cannot be used.
• Allen screwdriver/wrench


  This could be in the shape of a screwdriver or a wrench. Its function is to drive screws with hexagonal slot heads.
• Types of hammers


  • Claw hammer
  • Mallet (rubber head)
  • Ball-peen hammer
• Claw hammer


  This is a hammer with one side of the head split and curved, used for extracting nails.
• Mallet (rubber head)


  Has rubber head and is usually used to knock wooden pieces together, or to drive dowels or chisels.
• Ball-peen hammer


  It is also known as machinist's hammer used in metalworking.
• Pliers


  These tools are made from metal with insulators in the handle and are used for cutting, twisting, bending, holding and gripping wires and cables.
• Types of pliers


  • Combination pliers (lineman's pliers)
  • Side cutting pliers
  • Long nose pliers
• Combination pliers (lineman's pliers)


  This is used for gripping, holding, and cutting electrical wires and cables and even small nails. They are usually used by linemen in doing heavy tasks.
• Side cutting pliers


  This type of pliers is used for cutting fine, medium, and big wires and cables.
• Long nose pliers


  This is used for cutting and holding fine wires. This can reach tight spaces or small opening where other pliers cannot reach.
• Wire stripper


  This is a tool used for removing insulation of medium sized wires ranging from gauge #10 to gauge #16.
• Electrician's knife


  This is used by linemen to remove insulation of wire and cables in low and high voltage transmission lines.
• Portable electric drill


  A small drilling machine with a chuck capacity of ¼ to 1/2. It is used in making holes on metal sheets and concrete walls.
• Hacksaw


  This tool is used to cut metal conduit and armored cable.
• Convenience outlet


  This 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, multiplex and could be surface type or flush type.
• Types of convenience outlets

  • Surface type
  • Flush type
• Surface type outlet


  This type of outlet is typically mounted on the surface portion of the wall.
• Flush type outlet


  This type of outlet is typically buried in concrete and is attached to the utility box.
• Male plug


  This is a device inserted to a convenience outlet to allow the flow of electric current. This is used in making extension wires.
• Other common types of convenience outlets

  • Lamp holders
  • Switch
  • Fuse
  • Circuit breaker
  • Junction box
• Lamp holders


  These are devices that hold the lamp and are 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


  This is a device that connects and disconnects the flow of electric current in a circuit.
• Fuse


  This is a circuit protective device that automatically blows and cuts the current when overload or a short circuit happens.
• Circuit breaker


  This is a protective device that automatically trips and cuts the current when trouble in the circuit such as a short circuit or overload occurs. It comes in 2 poles, 3 poles and 4 poles.
• Junction box


  Is an octagonal shaped electrical material where the connections or joints of wires are being done. It is also where the flush type lamp holder is attached.
