Select electric and hydraulic tools TLE_IAEI9ET-Ia-e-1 1.1 Request tools, equipment and materials II. III. Objectives a. Request tools, equipment, and materials b. Identify electric and hydraulic tools for the task Background Information Electrical task 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. This lesson will discuss the function/use of each tool or equipment used in electrical wiring installations. INFORMATION SHEET 1.1 ELECTRICAL TOOLS AND MATERIALS Pliers. They could be with insulated or uninsulated handles. The handle insulation is not considered sufficient protection alone. Other safety precaution must be observed. The common types of pliers are: Slip joint Diagonal cutting Long nose Side cutting Snap ring Retainer ring 1 Screw drivers are used to drive and pull-out screws. They come in various sizes and shapes and with either sharp or square tips. The width of the screw driver should match the width of the screw slot. Common types of screw drivers are: Standard type Phillips Offset Wire puller (fish wire) is used to pull wires into the conduit or raceway. EMT bender is a tool used to bend electrical metal tubing. Drilling Equipment is needed to make holes in building structure for passage of wires and conduit in both new and old installation, indoor or outdoor wiring. Common types of drilling tools and equipment are: Electric drill Auger brace 2 Hand drill Gimlet Drill bits Masonry bit Soldering tools are used in making splices and taps connections of wires. Soldering gun Blow torch Hammers are used to drive and pull-out nails. They are made of either hard steel or plastic. A claw hammer with fiberglass insulated handle is specially designed for electricians. Common examples of hammer are: 3 Measuring tools and instrument. The electrician uses the following measuring tools and devices to measure value of voltage, current and resistance, wire length, opening sizes of wire, conduit and other items. Sawing and cutting tool. Two of the commonly used types of saws are: 4 Electrical Materials A. Wires and Cables a. Wire is a single, usually cylindrical, flexible strand or rod of metal. b. Cables are composed of two or more electric conductors insulated from one another. They are larger than wires Types of Wire and Cable Insulation Insulations Weather Proof Slow Burning Slow Burning Weather proof Rubber – Code Compound Heat Resistant Moisture Resistant Moisture and Heat Resistant Latex (Regular) Latex (Moisture Resistant) Mineral (Metal – Sheathed) Letter Type WP SB SBW R RH RW RH RU RU M Thermoplastic Compound Thermoplastic Moisture – Resistant Thermoplastic Moisture and Heat Resistant Thermoplastic Thermoplastic and Fibrous Outer Braid Thermoplastic and Asbestos Varnish Cambric Standard Black Heat Resisting Paper Solid Type 5 T TW THW TBS T V Oil – Filled Untreated Treated Asbestos Non – impregnated Impregnated Asbestos – Varnished – Cambric Outer Asbestos Braid Lead Covered Cotton Braid Covered Silicon Asbestos A and AA AI and AIA AVA AVB SA B. Electrical Boxes Electrical boxes are made of steel and nonmetallic materials(plastic). Metal boxes are made of #14 heavy galvanized steel and available in four principal shapes: square, octagon, rectangular, and circular. C. Fuses and circuit breakers Fuses and circuit breakers are electrical protective devices which are used to interrupt the flow of current when short circuit or over current occurs. They are available in different sizes and shapes and ratings. The common types are: 6 D. Switch It is an electrical device which is used to turn ON and OFF the circuit. E. Fittings and accessories These are some electrical materials which are commonly used to fit wiring devices during wiring installation. The following are some examples of these materials: 7 Anchor and fastening devices are as follows: a. Screw b. Bolts c. Screw anchor (tox) d. Expansion bolt e. Spring wing toggle bolt Requisition slip form is a written or printed request of something that is needed.
