Here is the converted markdown format of the document: # Electrical Tools and Equipment Prepared by: Sir. Junko Pacala ## Electrical Tools - Electrical tasks can be accomplished systematically to save time, effort, and resources. - Most of the work cannot be done using bare hands. To do the task, electrical tools or equipment are needed to perform the job. The next slide shows a picture of a standard screwdriver, Philips screwdriver and Stubby Screwdriver ## Screwdrivers - These tools are 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. ## 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. The slide shows a picture of a blue standard/flat screwdriver ## Philips Screwdriver - This has a cross tip resembling a positive (+) sign. This is used to drive screws with cross slot heads. The slide shows a picture of an orange Philips Screwdriver ## 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. The slide shows a picture of a Stubby Screwdriver with blue handle. ## 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. The sides shows a picture of a set of Allen Screwdrivers/ Wrenches. The next slide shows a picture of hammers. ## Hammers - These are tools used in driving or pounding and pulling out nails. They are 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 The slide shows a picture of a claw hammer. ## Mallet A mallet is a kind of hammer, often made of rubber or sometimes wood, that is smaller than a maul or beetle, and usually has a relatively large head. The term is descriptive of the overall size and proportions of the tool, and not the materials it may be made of, though most mallets have striking faces that are softer than steel. The slide shows a picture of a black rubber mallet ## Ballpeen hammer - A ball-peen (also spelled ball-pein hammer, also known as a machinist's hammer, is a type of peening hammer used in metalworking. It has two heads, one flat and the other, called the peen, rounded. It is distinguished from a cross-peen hammer, diagonal-peen hammer, point-peen hammer, or chisel-peen hammer by having a hemispherical peen. It is commonly used as a tool for metalworking. The slide shows a picture of a ballpeen hammer. The next slide shows a picture of pliers. # 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. The slide shows a picture of combination pliers. ## Side Cutting Pliers - This type of pliers is used for cutting fine, medium, and big wires and cables. The slide shows a picture of a side cutting pliers. ## Long Nose Pliers - This is used for cutting and holding fine wires. This can reach tight spaces or small openings where other pliers cannot reach and is also used in making terminal loops of copper wires. The slide shows a picture of long nose pliers. ## Wire Stripper - This is a tool used for removing insulation of medium-sized wires. The slide shows a picture of a wire stripper being used. ## Electrician's Knife - This is used by linemen to remove insulation of wire and cables in low and high voltage transmission lines. The slide shows a picture of an electrician's knife. ## Portable Electric Drill - A small drilling machine with a chuck capacity of 1/4ll to 3/8II. It is used in making holes on metal sheets and concrete walls. The slide shows a picture of a portable electric drill. ## Hacksaw - This tool is used to cut metal conduit and armored cable. The slide shows a picture of a hacksaw. ## Electrical Supplies and Materials Electrical materials are developed and constructed for a special purpose, such as to: 1. control the flow of current in an electrical circuit; 2. carry electrical current from the source to the load or current consuming apparatus; 3. hold and secure wires to its fixtures inside and outside houses and buildings; and 4. 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. 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, or multiplex and could be surface type or flush type. The slide shows the image of a surface type and flush type convenience outlet. ## Male plug - A device inserted to a convenience outlet to conduct electric current. A flat cord is attached to it on one end and the other end is connected to a current-consuming instrument or appliance. The slide shows a picture of male plugs ## Lamp Holders - Devices that hold and protect the lamp and are also called Lamp Sockets/Receptacles. These come in many designs and sizes. They are classified as flush, hanging (weather proof/chain), and surface types. The slide shows four images of different flushtype lamp holder. ## Switch - A device that connects and disconnects the flow of electric current in a circuit. There are many shapes, designs, and types and they are classified as hanging, flush, and surface types. The slide shows four images of different types of electrical switches. ## Fuse a circuit protective device that automatically blows and cuts the current when overload or short circuit happens. The slide shows the three types of Fuses (knife blade, cartridge and plug type) ## Circuit Breaker - a protective device used to automatically blow and cut the current when trouble in the circuit such as short circuit or overload occurs. The slide shows an image of a circuit breaker. ## Junction Box 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. This could be made of metal or plastic (PVC) Polyvinylchloride. The slide shows pictures of types of junction boxes; metal and plastic. ## Utility Box a rectangular shaped metallic or plastic (PVC) material in which flush type convenience outlet and switch are attached. The slide shows the images of two utility boxes made of metal and plastic. ## Flat Cord a duplex stranded wire used for temporary wiring installation and commonly used in extension cord assembly. It comes in a roll of 150 meters and sizes of gauge # 18 and gauge # 16 awg (American wire gauge). The slide shows a picture of a flat cord. ## Electrical wire/Conductor - a. Stranded wire which is made of multiple strands joined together to make a single wire. - b. Solid wire is made of a single strand of copper or aluminum wire. These are used in wiring installation inside and outside the buildings. The slide shows an image of stranded wire and solid wire. ## Conduits/Pipes electrical materials used as the passage of wires for protection and insulation. These could be rigid metallic, flexible metallic conduit (FMC), rigid nonmetallic (PVC), and flexible non-metallic or corrugated plastic conduit (CPC). The slides shows images of types of conduits and pipes. ## Clamps electrical materials used to hold and anchor electrical conduits to their proper position. The slide shows the image of metal clamp and plastic clamp. ## Connectors used to attach metallic or non-metallic conduit to the junction or utility boxes. The slide show the images of metal connector and flexible non metallic connector. ## Asynchronous Activity: - REVIEW THE TOPIC: 1. ELECTRICAL SUPPLIES AND MATERIALS 2. ANSWER WORKSHEET NO. 1
