  1. 3. Electromagnetic radiation at wavelengths in vacuum between the region of transition to X-rays and the region of transition to radio waves, that is approximately between 1 nm and 1000 micrometers
  2. 4. An area containing or designed to contain a laundry tray, clothes washer, or clothes dryer.
  3. 8. Equipment or materials to which has been attached a label, symbol, or other identifying mark of an organization that is acceptable to the authority having jurisdiction and concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials, and by whose labeling the manufacturer indicates compliance with appropriate standards or performance in a specified manner.
  4. 12. A wire that is run along with or integral with a cable or conductor to provide mechanical support for the cable or conductor
  5. 14. Electromechanical systems, equipment, apparatus, or components that are restored to operating conditions. This process differs from normal servicing of equipment that remains within a facility or replacement of listed equipment on a one-to-one basis
  6. 17. Accessible conductive parts bonded together to reduce voltage gradients in a designated area
  7. 20. The necessary equipment, consisting of a circuit breaker(s) or switch(es) and fusefs) and their accessories, connected to the serving utility and intended to constitute the main control and disconnect of the serving utility
  8. 22. A contact device installed at the outlet for the connection of an attachment plug, or for the direct connection of electrical utilization equipment designed to mate with the corresponding contact device. A single receptacle is a single contact device with no other contact device on the same yoke or strap. A multiple receptacle is two or more contact devices on the same yoke or strap. (CMP-18) Informational Note: A duplex receptacle is an example of a multiple receptacle that has two receptacles on the same yoke or strap.
  9. 23. The portion of the wiring system between the load side of the overcurrent device or power-limited supply and the connected equipment
  10. 24. The total components, circuits, and equipment up to and including the PV system disconnecting means that, in combination, convert solar energy into electric energy
Down
  1. 1. An inverter intended for use in parallel with power source(s) such as an electric utility to supply common loads and capable of delivering power to the utility
  2. 2. The machine that supplies the mechanical horsepower to a generator
  3. 5. A circuit in which any spark or thermal effect is incapable of causing ignition of a mixture of flammable or combustible material in air under prescribed test conditions
  4. 6. Capable of being reached for operation, renewal, and inspection
  5. 7. The overhead conductors between the serving utility and the service point
  6. 9. A conductor installed on the supply side of a service or within a service equipment enclosure(s), or for a separately derived system, that ensures the required electrical conductivity between metal parts required to be electrically connected
  7. 10. A circuit, other than field wiring, in which any arc or thermal effect produced under intended operating conditions of the equipment is not capable, under specified test conditions, of igniting the flammable gas-air, vapor-air, or dust-air mixture
  8. 11. A device that can provide an output dc voltage and current at a higher or lower value than the input dc voltage and current
  9. 13. A system that is capable of supplying power independent of an electric power production and distribution network.
  10. 15. The current delivered at a point on the system during a short-circuit condition
  11. 16. Equipment that changes dc to ac
  12. 18. Enclosures constructed so that dust will not enter under specified test conditions
  13. 19. A structure extending over the water and supported on a fixed foundation, or on flotation, that provides access to the water.
  14. 21. A room in a building for living, sleeping, eating, or cooking, but excluding bathrooms, toilet rooms, closets, hallways, storage or utility spaces, and similar areas
