Across
- 2. means: The switch, breaker, or device you use to completely shut off power to a circuit.
- 4. A normal, dry spot where your electrical equipment isn't overly exposed to damage, moisture, or explosions.
- 10. Any device, fixture, or material used to generate, transmit, or use electricity.
- 11. Any channel designed to hold wires (conduit, tubing, wireway, etc.).
- 13. It's connected to a source of voltage.
- 15. Hidden permanently by the building's structure.
- 20. The point where you actually tap into the wiring to run your equipment (a receptacle or light box).
- 21. (as applied to electrical equipment): It's certified by a legit organization (like the Standards Council of Canada) following the right safety rules.
- 23. The device at an outlet for plugging things in (a wall socket).
- 25. set: A flexible cord with a plug on one end and a connector on the other.
- 26. A switch used only to disconnect equipment, not meant to be opened while power is flowing.
- 29. A complete lighting unit (the fixture plus the lamp).
- 30. Separated from other metal surfaces by a material or air space that stops current flow.
- 34. (as applied to wiring methods): It's not permanently hidden in the wall/ceiling, and you can pull it out without wrecking the building.
- 36. (as applied to equipment): You can easily get to it because it's not locked up or too high up.
- 37. The max current a wire can safely handle continuously without getting too hot.
- 38. The circuit that runs from the main service box to the branch circuit overcurrent devices (like the wires supplying a subpanel).
- 40. A pipe-like channel (not tubing) that wires are pulled through.
- 42. tray: A support system (like a trough or ladder) for running wires and cables.
- 43. conductor: No covering.
- 45. (as applied to live parts): Live parts you can accidentally touch.
- 48. A completely enclosed metal trough for wires that allows them to be laid in and removed after installation.
- 49. conductor: Has a full dielectric cover for proper electrical strength.
- 51. How regularly a piece of equipment is expected to run (e.g., continuous, intermittent, short-time).
- 53. authority: The power company!
- 54. person: Someone qualified, or someone who's been warned about the dangers and told they can work with the equipment.
- 55. An enclosure where dust can't get inside.
- 56. The assembly with buses, breakers, and controls installed in a cabinet (your fuse/breaker panel).
- 57. You can quickly get to it without climbing or moving stuff.
Down
- 1. Over 1000 V AC or over 1500 V DC.
- 3. Up to 30 V AC or 60 V DC.
- 5. Protected by covers, fences, barriers, etc., to prevent accidental contact.
- 6. An area where explosive gases or dusts are (or might be) present, requiring special electrical gear.
- 7. A room or series of rooms rented under one agreement (includes dwelling units, hotel rooms, etc.).
- 8. All the wiring and connection work from where the power company hands it off to where your equipment uses it.
- 9. location: Where liquids might drip, splash, or flow onto the electrical gear.
- 12. A metal wrapping for a wire to protect it physically, but it doesn't make it perfectly sealed.
- 14. A device that shuts off the circuit quickly if it detects a tiny bit of current leaking to ground (for safety).
- 16. A place where people assemble, process, or store stuff (not just an office or dwelling).
- 17. A fuse or circuit breaker that automatically opens the circuit under too much current (overload or short-circuit).
- 18. A box tough enough to contain an internal explosion and not let it spark a surrounding explosive atmosphere.
- 19. The metal rod or buried object connecting the grounding conductor to the earth.
- 22. permission: Written approval from the inspection department.
- 24. Safely and effectively connected to the earth (ground).
- 27. conductor: Has a dielectric cover, but it's not thick enough to be considered insulation.
- 28. A standalone structure or one separated by firewalls.
- 31. The people enforcing the rules are okay with it.
- 32. A complete factory-made wire assembly, possibly with multiple insulated conductors.
- 33. (as applied to electrical equipment): No electrical connection to a power source, no charge, and at the same voltage as the earth (ground).
- 35. circuit: The wiring that runs from your fuse/breaker panel out to your light(s) or outlet(s).
- 39. Someone who knows the equipment, how it works, and the dangers involved.
- 40. Anything that's built to carry electric current (a wire).
- 41. A suite (like an apartment) with cooking, living, sleeping, and bathroom facilities.
- 44. Connecting all the metal, non-current-carrying parts together to create a safe, low-resistance path for electricity.
- 46. A continuous cover on a cable, primarily to provide a hermetic (air/liquid-tight) seal.
- 47. A room with a tub or shower, and maybe a sink/toilet too.
- 50. Over 30 V AC up to 1000 V AC, or over 60 V DC up to 1500 V DC.
- 52. (as applied to electrical equipment): Gear designed to be easily moved, usually powered by a flexible cord and plug.
