3. Terminologies Supply – to provide with Materials – consumable Utility – designed for general use.

4. The following are electrical devices and materials used in the assembly of basic electrical gadgets such as extension cord, lamp shade, etc. These are developed and constructed for a special purpose such as to: Control the flow of current in an electrical circuit. Carry electrical current from the source to the load or current consuming apparatus.

5. Control the flow of current in an electrical circuit. Carry electrical current from the source to the load or current consuming apparatus. Hold and secure wires to its fixtures inside and outside houses and buildings. Protect the houses, buildings, appliances and instruments from any destruction and damage.

6. CONVENIENCE OUTLET Convenience Outlet is 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 usually fastened on the wall or connected in an extension cord. It maybe single, duplex, triplex or multiplex and could be surface type or flush type .

7. CONVENIENCE OUTLET

8. MALE / AC PLUG Male Plug - is 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.

9. MALE / AC PLUG

10. LAMP HOLDER Lamp Holder – This is an electrical device that is used to hold and protect incandescent or compact fluorescent lamp. It is also called as “Lamp Socket/Receptacle”.

11. LAMP HOLDER

12. SWITCH Switch - is a device that connects and disconnects the flow of electric current in a circuit. Switches are classified as hanging, flush and surface types.

13. SWITCH

14. FUSE Fuse - a circuit protective device that automatically blows and cuts the current when overload or short circuit happens.

20. CIRCUIT BREAKER Circuit Breaker - a protective device used to cut or interrupt automatically the current when trouble in the circuit such as short circuit or overload occurs.

21. CIRCUIT BREAKER

22. UTILITY BOX Utility Box - a rectangular shaped metallic or plastic (PVC) material in which flush type convenience outlet and switch are attached.

23. UTILITY BOX

24. JUNCTION BOX 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 .

25. JUNCTION BOX

26. FLAT CORD Flat Cord - a duplex stranded wire used for temporary wiring installation and commonly used in extension cord assembly.

27. FLAT CORD

28. ELECTRICAL WIRE OR CONDUCTOR Electrical Wire/Conductor - electrical material that could be: Stranded wire which is made of multiple strands joined together to make a single wire. Solid wire is made of a single strand of copper or aluminum wire. These are used in wiring installation inside and outside the buildings.

29. ELECTRICAL WIRE OR CONDUCTOR

30. ELECTRICAL CONDUITS / PIPES Electrical Conduits/Pipes - electrical materials used as the passage of wires for protection and insulation. These could be rigid metallic, flexible metallic conduit (FMC), rigid non-metallic (PVC), and flexible non-metallic or corrugated plastic conduit (CPC).

31. ELECTRICAL CONDUITS / PIPES Rigid Non-metallic conduit (PVC) and Metallic conduit

32. ELECTRICAL CONDUITS / PIPES Flexible Non-metallic conduit or corrugated plastic conduit (CPC)

33. ELECTRICAL CONDUITS / PIPES

34. ELECTRICAL TAPE Electrical Tape – used to protect and cover live or open wires.

35. ELECTRICAL TAPE

36. ACTIVITY By group, name the 5 actual electrical supplies and materials that your groupmates brought to school. Write your answers in a 1/4 sheet of paper. Afterwards, present your answers to the class using the realias. Note: every correct answer is equivalent to 4 points. 20 for the highest score and 0 for the lowest score.

37. Quiz Direction: Identify the given electrical supply. Write the answer at the back of your big notebook.

38. ELECTRICAL CONDUITS AND ACCESSORIES Prepared by: MR. JHUNALVIN B. SANTOS TLE 8 Teacher

39. TYPES OF ELECTRICAL CONDUITS

40. PVC CONDUIT PIPE PVC Conduit Pipe – are popular type of electrical conduit used for above ground and underground applications. These conduits are made of high quality PVC and are flexible in nature. The pipes have high electrical strength and impact resistance.

41. PVC CONDUIT PIPE

42. RIGID STEEL CONDUIT Rigid Steel Conduit – This heavy-duty pipe has threaded ends.

43. ELECTRICAL METALLIC TUBING (EMT) Electrical Metallic Tubing (EMT) – These conduits are relatively easy to bend, cut, and form. This light gauge pipe is also known as thin wall conduit.

44. ELECTRICAL METALLIC TUBING (EMT)

45. NONMETALLIC CONDUITS OR PVC CONDUITS Nonmetallic Conduits or PVC Conduits – These are circular in shape and generally corrugated. These conduits are used in underground installations. These are popular because these provide high strength, have a low absorption rate, watertight joints, and have low installation costs.

46. NONMETALLIC CONDUITS OR PVC CONDUITS

47. GALVANIZED RIGID CONDUITS (GRC) Galvanized Rigid Conduits (GRC) – These metallic conduits are coated with zinc for increasing resistance to corrosion and abrasion.

48. GALVANIZED RIGID CONDUITS (GRC)

49. INTERMEDIATE METAL CONDUITS (IMC) Intermediate Metal Conduits (IMC) - These have circular raceways that are rigid and have thinner walls as compared to rigid metal conduits.

50. INTERMEDIATE METAL CONDUITS (IMC)

51. FLEXIBLE METALIC CONDUIT Flexible Metallic Conduit – This is a variety of piping used to hold electrical wires and similar cabling.

52. FLEXIBLE METALIC CONDUIT

53. ELECTRICAL CONDUIT ACCESSORIES

54. CONDULETS Condulets – These are used for a fitting resembling a pipe or box with a removable cover for access to electric conduits.

55. CONDULETS

56. CONDULETS

57. CLAMPS Clamps- electrical materials used to hold and anchor electrical conduits to their proper position.

58. CLAMPS

59. CONNECTORS Connectors – These are devices used for joining electrical circuits as an interface using a mechanical assembly. Also, these are used for attaching metallic or non-metallic conduit to the junction or utility boxes.
