Electrical Tools and Materials

• Study notes on electrical tools and their functions

Electrical Materials

• Utility Box: Metallic or plastic (PVC) rectangular box for attaching flush-type convenience outlets and switches.
• Connectors/Adapters: Connects various electrical components.
• Male Plug: Device inserted into a convenience outlet to conduct electric current.
• Fuse: A circuit protection device that automatically blows and cuts the current during an overload or short circuit.
• Junction Box: An octagonal electrical box, either metal or plastic (PVC), used for wire connections or splices and attaching flush-type lamp holders.
• Conduits: Electrical materials that protect and insulate wires; types include rigid metallic, flexible metallic (FMC), rigid nonmetallic (PVC), and flexible non-metallic or corrugated plastic (CPC).
• Circuit Breaker: A protective device that automatically blows and cuts the current when there's a short circuit or overload.
• Electrical Wires: Wires or cords that provide a path for electric current to flow.
• Lamp Sockets / Holders: Devices that hold and protect lamps; come in flush, hanging, and surface types.
• Fuse Panel / Safety Switch: Immediately turns off the electric supply when a fault is detected.
• Switches: Devices that connect and disconnect electric current flow in a circuit; various shapes, designs, and types exist (hanging, flush, and surface types).
• Convenience Outlet: Acts as a source of electricity where the male plug is inserted; comes in single, duplex, triplex, and multiplex types.
• Clamps: Electrical material used to hold and anchor electrical conduits in position.
• Connectors: Used to attach metallic or non-metallic conduits to junction or utility boxes.
• Flat Cord: A duplex stranded wire for temporary wiring, typically used in extension cords; comes in 150-meter rolls in gauge #18 and #16 AWG (American wire gauge).

Electrical Tools

• Screwdrivers: Steel tools hardened and tempered at the tip for loosening or tightening screws with slotted heads; available in various sizes and shapes.
• Hammers: Tools for pounding, driving, and pulling out nails; made of hard steel, wood, plastic, or rubber.
• Pliers: Metal tools with insulated handles for holding, twisting, bending, cutting, and gripping wires and cables.
• Wire Stripper: Removes insulation from medium-sized wires, ranging from gauge #10 to gauge #16.
• Electrician's Knife: Used to remove insulation from wires and cables in low and high-voltage transmission lines.
• Portable Electric Drill: A small drilling machine with a chuck capacity of ¼‖ to 3/8‖, used for making holes in metal sheets and concrete walls
• Hacksaw: Tool used to cut metal conduits and armored cables.
