• Electrical Installation and Maintenance (EIM) Module 1: Preparing Electrical Tools and Materials
• Learning Objective


  Prepare electrical materials and tools for the task
• Circuit breaker


  Designed to protect electrical circuit devices from damage caused by overload or short circuit and its basic function is to interrupt the flow of current when fault is detected
• Circuit breaker


  Provides protection against overload and short circuits
• Philip screw driver


  Tool used to tighten and loosen screws with cross slot heads
• Electrical wire


  Allows the current to flow through the circuit
• Junction box


  Made of metal and plastic box in an octagonal form used in wiring installation
• Electrical tools and materials are essential elements in the preparation for a specific electrical job. Using appropriate materials and tools will help you perform the different tasks easily and efficiently.
• Lesson 1 Preparing Electrical Tools and Materials
• Conductor


  A wire or a cord which provides path for current flow
• Hot wire


  A wire through which current flows
• RSC


  Rigid Steel Conduit
• Single Pole Switch


  A simple on/off switch that connects and disconnects two terminal to control the flow of current in a circuit
• PVC Connectors


  A type of electrical fittings used to hold and connect conduit in a box
• Incandescent bulb


  An electric light with a wire filament heated until it glows
• Heat gun


  A power tool used in bending PVC conduit that blows hot air
• Lamp holder


  A type of device used for holding compatible light bulb
• Metallic Conduits


  Metal raceways classified into four; rigid steel conduit (RSC), intermediate metallic conduit or tubing (IMC or IMT), electrical metallic conduit or tubing (EMC or EMT) and the flexible metallic conduit (FMC)
• PVC


  Polyvinyl Chloride
• Electrical tools


  Handheld devices that support in achieving a task. It is designed to aid and protect the worker against electric shock while allowing him/her to work swiftly and comfortably
• Electrical materials


  Used to grasp and anchor electrical conduits to keep strong and stable position. Electrical fittings are most likely used to attach metallic and non-metallic conduit respectively
• Preparing Electrical Tools and Materials: Tools and materials are very essential to aid in any electrical operation which everyone should have sufficient knowledge and manipulative skills in proper handling of tools, electrical instruments, materials and devices in accordance to the job requirements.
