Across
  1. 3. breaker - overcurrent protection device that automatically shuts off the current in a circuit if an overload occurs
  2. 4. - luminous electrical discharge (bright, electrical sparking) through the air that occurs when high voltages exist across a gap between conductors
  3. 6. - material in which an electrical current moves easily
  4. 8. - overcurrent protection device that has an internal part that melts and shuts off the current in a circuit if there is an overload
  5. 10. current - electrical current that passes through a part of the body
  6. 12. fault - loss of current from a circuit to a ground connection
  7. 14. - personal protective equipment (eye protection, hard hat, special clothing, etc.)
  8. 15. - movement of electrical charge
  9. 17. - physical electrical connection to the earth
  10. 19. - strength of an electrical current, measured in amperes
  11. 21. - measure of electrical force
  12. 22. - complete path for the flow of current
  13. 23. - material's ability to decrease or stop electrical current
  14. 26. wiring - permanent wiring installed in homes and other buildings
  15. 27. - amount of energy used each second, measured in watts
  16. 29. used to describe the rate of electrical output
Down
  1. 1. - joining electrical parts to assure a conductive path
  2. 2. - at ground potential (0 volts) because of a connection to ground
  3. 5. - material that does not conduct electricity easily
  4. 7. - Occupational Safety and Health Administration-Federal agency in the U.S. Department of Labor that establishes and enforces work-place safety and health regulations
  5. 9. person - someone who has received mandated training on the hazards and on the construction and operation of equipment involved in a task
  6. 11. - covering or barrier that separates you from live electrical parts
  7. 13. - shutting off the energy sources to circuits and equipment and depleting any stored energy
  8. 16. current - any current that is not in its intended path
  9. 18. - too much current in a circuit
  10. 20. gauge - wire size or diameter (technically, the cross-sectional area)
  11. 22. - cardiopulmonary resuscitation-emergency procedure that involves giving artificial breathing and heart massage to someone who is not breathing or does not have a pulse (requires special training)
  12. 24. - automatic opening (turning off) of a circuit by a GFCI or circuit breaker
  13. 25. - chance that injury or death will occur
  14. 28. - unit of measurement for electrical resistance
  15. 30. - unit used to measure current
