(d) Is rated for operation at a frequency of sixty hertz.
10. "Metal halide lamp" means a high intensity discharge lamp in which the major portion of the light is produced by radiation of metal halides and their products of dissociation, possibly in combination with metallic vapors.
11. "Metal halide lamp fixture" means a light fixture designed to be operated with a metal halide lamp and a ballast for a metal halide lamp.
12. "Portable electric spa" means a factory-built electric spa or hot tub that is supplied with equipment for heating and circulating water.
13. "Probe start metal halide ballast" means a ballast used to operate metal halide lamps that does not contain an ignitor and which instead starts lamps by using a third starting electrode probe in the arc tube.
14. "Pulldown refrigerator" means a commercial refrigerator specifically designed to rapidly reduce all integrated product temperatures from ninety degrees fahrenheit to thirty-eight degrees fahrenheit over a twelve hour period when fully loaded with beverage containers.
15. "Residential pool pump" means a pump that is used to circulate and filter residential swimming pool water in order to maintain clarity and sanitation and that consists, in part, of a motor and an impeller and housing.
16. "Residential pool pump motor" means a definite purpose motor designed for use in a residential pool pump.
