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