Across
  1. 3. outlet: A device attached to a circuit to allow electricity to be drawn off for appliances or lighting.
  2. 4. Set of wires, usually encased in an outer protective jacket.
  3. 7. – Ground-Fault Circuit-Interrupter Device that disconnects a circuit whenever it detects that the electric current is not balanced between the hot side and the return neutral side. Current leakage through the body of a person who is grounded and accidentally touching the energized
  4. 9. Magnetism that occurs when a current is passed through a device of coiled wire wrapping an iron core.
  5. 12. The part of an electrical wiring system that extends from the panel to a set of outlets.
  6. 13. The internal material of a cable or cord that conducts electricity. Copper is the most common material used for electrical wiring. Silver is the best conductor, but is expensive. Because it does not corrode, gold is used for high-quality surface-to-surface contacts.
  7. 15. breaker A safety device that breaks the circuit when it is overloaded.
  8. 18. Device for interrupting an electrical circuit to prevent excess current.
  9. 20. The complete path of an electric current.
  10. 22. Conductor through which electric current enters or leaves a device or material.
  11. 23. – American Wire Gauge Standardized wire gauge system in the US for non-ferrous conductors (i.e., non-iron and non-steel). Lower gauge numbers indicate larger conductor size.
  12. 24. Current Current which moves in a single direction in a steady flow. Normal household electricity is alternating current (AC) which repeatedly reverses its direction. However, many electronics devices require DC (eg. battery powered devices), and therefore must convert household current into DC before use.
Down
  1. 1. Pipes or enclosed channels through which wires are run.
  2. 2. receptacle Type of electrical receptacle or outlet that accommodates two plugs (one above the other).
  3. 5. – Amps/Amperes/Ampacity/Rated Amperage Measurement of the flow rate of electricity. If you think in terms of water through a hose, amperage would be a measure of water volume flowing through the hose.
  4. 6. Safety device consisting of a strip of wire that melts and breaks an electric circuit if the current exceeds a safe level.
  5. 7. Unit of thickness of a wire or metal sheet. Smaller gauge is larger wire.
  6. 8. line Conductors run to supply power from the main service panel to a sub panel.
  7. 10. The rate of flow of electrical energy through a conductor or wire, comparable to the amount of water flowing in a pipe. Electric current is measured in amperes or “amps”.
  8. 11. The flow of electrons in a conductor.
  9. 14. – Alternating Current Electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction. AC is the form in which electric power is delivered to businesses and residences.
  10. 16. circuit Closed path that allows energy or electricity to flow.
  11. 17. Visible discharge or electricity between two points.
  12. 18. Container in which chemical energy is converted into electricity.
  13. 19. To compress a wire in an electrical fitting.
  14. 21. panel Housing box that divides an electrical power feed system into subsidiary circuits (also known as a breaker box, panel board, fuse box, or distribution panel).
  15. 22. (electrical metallic tubing): Thin-walled metal conduit used as a raceway.
