2. Adapter • Placed on the end of a cord to adapt a two prong plug to a three prong plug. The green eyelet is attached to the center screw of the receptacle cover for grounding.

3. Armored Cable • Used mainly for inside wiring. Consists of metal armor and each of the copper conductors insulated by plastic or rubber insulation.

4. Cartridge Fuse • A device that will open a circuit and stop the flow of current when an overload or short occurs. This fuse appears in a cylinder shape with smooth ferrules at both ends.

5. Circuit breaker (three-pole; two pole) • Protective device which protects the circuit from overload. When an overload occurs, the breaker will trip, automatically opening the circuit.

6. Circuit Tester (AC or DC) • A simple device used to test the circuit and determine if power is on or off.

7. Clamp-on Circuit Tester • A portable testing instrument that snaps around the conductor to measure AC amperage.

8. Conduit Bender • Used to bend angles in thin-walled conduit.

9. Cord Cap • Used as a male plug. The cord cap is used on power tools as well as appliances in the home.

10. Cord Connector • Designed to accommodate the cord the cord cap and is sometimes referred to as the female plug.

11. Dimmer Switch • A electric light switch that may be used to apply partial power to a light fixture.

12. Duplex Receptacle • A plug for electrical devices which will accommodate two plugs (cord caps) at the same time.

13. EMT Connector • Used to connect two pieces of conduit end to end.

14. EMT Elbow • Allows a corner to be made when connecting two pieces of conduit.

15. Fishing Tape • Used to pull electrical wires through conduit.

16. Flexible Metallic Conduit • A piece of spiral shaped, interlocking zinc coated steel used to protect wiring.

17. Flexible Non-Metallic Conduit • Commonly used to connect stationary equipment to a power source.

18. Fuse Puller • Used to pull or install cartridge and knife fuses.

19. Ground Fault Interrupter • An electric outlet commonly used in areas where water is present. Provides additional safety as it contains a breaker mechanism.

20. Insulated Staple • A staple used to fasten low voltage wires to structures and has a double fold of insulation over the galvanized staple.

21. Junction Box • Device used for housing splices and mounting different types of electric fixtures.

22. Key Stock • A square metal stock in various sizes that is placed in a round shaft to hold pulleys and pillow blocks in place. (could be used with electric motors or on small gas engines)

23. Knife Fuse • It is another type of cartridge fuse and is rated for electrical service of 60 to 600 amperes.

24. Multi-Meter • A specifically designed meter used to measure AC or DC voltage, current, and ohms with accuracy.

25. Non-Metallic Cable • Must be used for inside wiring. Consists of a thermoplastic sheath, insulated conductors, and is available with or without grounding wire.

26. Non-Metallic Cable Ripper • Used to aid in the removal of the non-metallic cable insulation in order to expose the insulated wires inside.

27. Non-Metallic Clamp • Used to fasten non-metallic cable to boxes.

28. Plastic Covered Electric Cord • Used for household appliances. The stranded copper conductors are covered with plastic insulation.

29. Rigid Conduit • Used both inside and outside to provide mechanical and fire protection for wiring.

30. Romex Clamp • A specifically designed camp for non-metallic sheath cable in switch boxes.

31. Rubber Covered Electric Cord • The copper conductors are individually insulated and wrapped with paper.

32. Service Entrance Panel • The entry point for electrical power into a building. Circuit breakers are connected into the electrical system at this point.

33. Electric Soldering Iron/Gun • Used as a source of heat for metals being joined by soldering.

34. Solderless Connector • Used for splicing electrical wiring without the use of solder or tape.

35. Switch Box • Used to mount switches or receptacles flush in the wall.

36. Thermoplastic Electric Wire (TW) • Most commonly used for conductors in nonmetallic cable.

37. Thin-Walled Conduit • Also referred to as Electrical Metallic Tubing (EMT) which is used inside to provide mechanical and fire protection.

38. Three Way Toggle Switch • An electrical device used to control a circuit from two different locations. The name of the three way switch is derived from its three terminals on the switch.

39. Toggle Switch • Electrical device used to open and close a circuit from one location.

40. Uni-Bit • A cone shaped drill bit commonly used to drill holes for conduit in metal boxes or metal siding.

41. Water Proof Box • A variety of electrical boxes designed for external use where they are exposed to weather.

42. Wire Nuts • Used to connect electrical wires rapidly without the use of tape.

43. Water Proof Tape • Self-Sealing tape which chemically bonds itself to produce a waterproof splice.

44. Wire Solder • Used for soldering sheet metal seams, electrical connections and other repair work. It is available in solid or flux-cored wire.

45. Wire Stripper • Used to remove insulation from wire without damaging the wire.

46. Wire Terminals • Crimped onto the end of wire so that the wire may be attached to a screw or terminal.

47. Plug Fuse • A protective device used for overloads up to 30 amperes.

48. Rigid Non-Metallic Conduit • Commonly used to connect underground lines to a service entrance panel.
