Vermont § 2793 - Definitions As used in this chapter:

§ 2793. Definitions As used in this chapter:

• (1) “Ballast” means a device used with an electric discharge lamp to obtain necessary
  circuit conditions (voltage, current, and waveform) for starting and operating the
  lamp. (2) “Commissioner” means the Commissioner of Public Service. (3) “Compensation” means money or any other valuable thing, regardless of form, received
  or to be received by a person for services rendered. (4) “Electricity ratio (ER)” is the ratio of furnace electricity use to total furnace
  energy use. ER = (3.412*EA/iE)/(1000*EF + 3.412 EA/iE) where EAE (average annual auxiliary electrical consumption) and EF (average annual fuel energy consumption) are defined in 10 C.F.R. Part 430, Subpart B, Appendix N. (5) “High-intensity discharge lamp” means a lamp in which light is produced by the passage
  of an electric current through a vapor or gas and in which the light-producing arc
  is stabilized by bulb wall temperature, and the arc tube has a bulb wall loading in
  excess of three watts per square centimeter. (6) “Medium voltage dry-type distribution transformer” means a transformer that: (A) has an input voltage of more than 600 volts but less than or equal to 34,500 volts; (B) is air-cooled; (C) does not use oil as a coolant; and (D) is rated for operation at a frequency of 60 hertz. (7) “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. (8) “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. (9) “Probe-start metal halide ballast” means a ballast used to operate metal halide lamps
  that does not contain an ignitor and that instead starts lamps by using a third starting
  electrode probe in the arc tube. (10) “Residential boiler” means a self-contained appliance that is primarily designed for
  space heating by means of steam or hot water and that uses only single-phase electric
  current in conjunction with natural gas, propane, or home heating oil and that has
  a heat input rate of less than 300,000 Btus per hour. (11) “Residential furnace” means a self-contained space heater designed to supply heated
  air through ducts of more than 10 inches in length and that utilizes only single-phase
  electric current or single-phase electric current or DC current in conjunction with
  natural gas, propane, or home heating oil, and that: (A) is designed to be the principal heating source for the living space of one or more
  residences; (B) is not contained within the same cabinet with a central air conditioner whose rated
  cooling capacity is above 65,000 Btus per hour; and (C) has a heat input rate of less than 225,000 Btus per hour. (12) “Single-voltage external AC to DC power supply” means a device that: (A) is designed to convert line voltage AC input into lower voltage DC output; (B) is able to convert to only one DC output voltage at a time; (C) is sold with, or intended to be used with, a separate end-use product that constitutes
  the primary power load; (D) is contained within a separate physical enclosure from the end-use product; (E) is connected to the end-use product via a removable or hard-wired male or female electrical
  connection, cable, cord, or other wiring; (F) does not have batteries or battery packs, including those that are removable, that
  physically attach directly to the power supply unit; (G) does not have a battery chemistry or type selector switch and indicator light; or
  does not have a battery chemistry or type selector switch and a state of charge meter;
  and (H) has a nameplate output power less than or equal to 250 watts. (13) “State-regulated incandescent reflector lamp” means a lamp that is not colored or
  designed for rough or vibration service applications, that has an inner reflective
  coating on the outer bulb to direct the light, an E26 medium screw base, and a rated
  voltage or voltage range that lies at least partially within 115 and 130 volts, and
  that falls into either of the following categories: (A) a blown PAR (BPAR), bulged reflector (BR), or elliptical reflector (ER) bulb shape,
  with a diameter that equals or exceeds 2.25 inches; or (B) a reflector (R), parabolic aluminized reflector (PAR), or similar bulb shape with
  a diameter of 2.25 to 2.75 inches. (14)(A) “Transformer” means a device that consists of two or more coils of insulated wire
  and that is designed to transfer alternating current by electromagnetic induction
  from one coil to another, in order to change the original voltage or current value. (B) The term “transformer” does not include:
