• Prepared by Sir. Junko Pacala.
• Electrical tasks can be accomplished systematically, to save time, effort, and resources.
• Electrical tools or equipment are needed to perform tasks that cannot be done using bare hands.

Screwdrivers

• Made of steel hardened and tempered at the tip.
• Used to loosen or tighten screws with slotted heads.
• Available in various sizes and shapes.

Standard/Flat Screwdriver

• The blade tip is wedge-shaped and looks like a negative (-) sign.
• Used to drive screws with a single slot head.

Philips Screwdriver

• Has a cross tip resembling a positive (+) sign.
• Used to drive screws with cross slot heads.

Stubby Screwdriver

• Available as standard or Philips screwdrivers, featuring a 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

• It is shaped like a screwdriver or wrench.
• Used to drive screws with hexagonal slot heads.

Hammers

• Used to drive, pound, or pull out nails.
• Made of hard steel, wood, plastic, or rubber.

Claw Hammer

• A hammer with one side of the head split and curved.
• Used for extracting nails.

Mallet

• A kind of hammer.
• Often made of rubber or sometimes wood.
• Smaller than a maul or beetle.
• Usually has a relatively large head.
• Most mallets have striking faces that are softer than steel.

Ballpeen Hammer

• Also known as a machinist's hammer.
• A type of peening hammer used in metalworking.
• Has two heads, one flat and one rounded peen.
• Distinguished by a hemispherical peen, and commonly used as a tool for metalworking.

Combination Pliers (Lineman's Pliers)

• Used for gripping, holding, and cutting electrical wires, cables, and even small nails.
• Usually used by linemen in doing heavy tasks.

Side Cutting Pliers

• Used for cutting fine, medium, and big wires and cables.

Long Nose Pliers

• Used for cutting and holding fine wires.
• Can reach tight spaces or small openings other pliers cannot reach.
• Also used in making terminal loops of copper wires.

Wire Stripper

• Used for removing insulation of medium-sized wires.

Electrician's Knife

• 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 1/4" to 3/8".
• Used in making holes on metal sheets and concrete walls.

Hacksaw

• Used to cut metal conduit and armored cable.

Electrical Supplies and Materials

• Developed and constructed for a purpose, such as to:
  • Control the flow of current in an electrical circuit.
  • Carry electrical current from the source to the load.
  • Hold and secure wires to fixtures inside and outside.
  • Protect houses, buildings, appliances, and instruments from destruction and damage.

Convenience Outlet

• A device that acts as a convenient source of electrical energy for current-consuming appliances.
• Where the male plug of an appliance is inserted.
• Usually fastened on the wall or connected in an extension cord.
• Can be single, duplex, triplex, or multiplex.
• Can be surface type or flush type.

Male Plug

• A device inserted into a convenience outlet to conduct electric current.
• A flat cord is attached to it on one end and is connected to a current-consuming instrument or appliance in the other end.

Lamp Holders

• Also called lamp sockets/receptacles.
• Hold and protect the lamp.
• Available in many designs and sizes.
• Classified as flush, hanging (weather proof/chain), and surface types.

Switch

• A device that connects and disconnects the flow of electric current in a circuit.
• There are many shapes, designs, and types.
• Classified as hanging, flush, and surface types.

Fuse

• A circuit protective device that automatically blows and cuts the current when an overload or short circuit occurs.
• Different types include knife blade, cartridge, and plug type.

Circuit Breaker

• Protective device used to automatically blow and cut the current when trouble in the circuit, such as short circuit or overload, occurs.

Junction Box

• Octagonal shaped electrical material where the connections or joints of wires are located.
• The flush type lamp holder is attached there as well.
• Can be made of metal or plastic (PVC) polyvinylchloride.

Utility Box

• A rectangular shaped metallic or plastic (PVC) material.
• Flush type convenience outlet and switch are attached.

Flat Cord

• A duplex stranded wire used for temporary wiring installation.
• Commonly used in extension cord assembly.
• It comes in a roll of 150 meters.
• Available in sizes of gauge #18 and gauge #16 AWG (American wire gauge).

Electrical Wire/Conductor

• Stranded wire which is made of multiple strands joined together to make a single wire.
• Solid wire is made of a single strand of copper or aluminum wire, used in wiring installation inside and outside the buildings.

Conduits/Pipes

• Electrical materials used as the passage of wires for protection and insulation.
• These can be rigid metallic, flexible metallic conduit (FMC), rigid nonmetallic (PVC), and flexible non-metallic or corrugated plastic conduit (CPC).

Clamps

• Electrical materials used to hold and anchor electrical conduits to their proper position.

Connectors

• Used to attach metallic or non-metallic conduit to the junction or utility boxes.
