				  CHAPTER 42 SPAS, HOT TUBS, AND HYDROMASSAGE TUBS SECTION E4201.1 SCOPE.
The provisions of this chapter shall apply to the
				  construction and installation of electric wiring and equipment associated with
				  all hot tubs and spas, and hydromassage bathtubs, whether permanently installed
				  or storable, and shall apply to metallic auxiliary equipment, such as pumps,
				  filters, and similar equipment. Electrical installations of in-ground, above
				  ground and therapeutic pools and ornamental fountains shall comply with the
				  requirements of the Indiana Electrical Code, 675 IAC 17. SECTION E4201.2
				  DEFINITIONS. (680.2)
CORD-AND-PLUG-CONNECTED LIGHTING ASSEMBLY. A lighting
				  assembly consisting of a cord-and-plug-connected transformer and a luminaire
				  intended for installation in the wall of a spa or hot tub. DRY-NICHE LUMINAIRE.
				  A luminaire intended for installation in the floor or wall of a spa.
HYDROMASSAGE BATHTUB. A permanently installed bathtub
				  equipped with a recirculating piping system, pump, and associated equipment
				  designed so it can accept, circulate, and discharge water upon each use.
				  LOW-VOLTAGE CONTACT LIMIT. A voltage not exceeding the following values:
1. 15 volts (RMS) for sinusoidal
				ac.
2. 21.2 volts peak for
				nonsinusoidal ac.
3. 30 volts for
				continuous de.
4. 12.4 volts peak
				for de that is interrupted at a rate of 10 to 200 Hz. MAXIMUM WATER LEVEL. The
				highest level that water can reach before it spills out.
NO-NICHE LUMINAIRE. A luminaire intended for installation
				  above or below the water without a niche. PACKAGED SPA OR HOT TUB EQUIPMENT
				  ASSEMBLY. A factory-fabricated unit consisting of water circulating heating and
				  control equipment mounted on a common base intended to operate a spa or hot
				  tub. Equipment may include pumps, air blowers, heaters, luminaires, controls,
				  and sanitizer generators. SELF-CONTAINED SPA OR HOT TUB. A factory-fabricated
				  unit consisting of a spa or hot tub vessel with all water circulating, heating,
				  and control equipment integral to the unit. Equipment may include pumps, air
				  blowers, heaters, luminaires, controls, and sanitizer generators.
SPA OR HOT TUB. A hydromassage pool, or tub for recreational
				  or therapeutic use, not located in health care facilities, designed for
				  immersion of users, and usually having a filter, heater, and motor-driven
				  blower. They are installed indoors or outdoors, on the ground or supporting
				  structure, or in the ground or supporting structure. Generally, a spa or hot
				  tub is not designed or intended to have its contents drained or discharged
				  after each use. STORABLE/PORTABLE SPAS AND HOT TUBS. A spa or hot tub that is
				  constructed on or above the ground with nonmetallic, molded polymeric walls or
				  inflatable fabric walls regardless of dimension.
THROUGH-WALL LIGHTING ASSEMBLY. A lighting assembly intended
				  for installation above grade, on or through the wall of a pool, consisting of
				  two interconnected groups of components separated by the pool wall. WET-NICHE
				  LUMINAIRE. A luminaire intended for installation in a structure where the
				  luminaire will be completely surrounded by water.
SECTION E4202 WIRING METHODS FOR POOLS, SPAS, HOT TUBS, AND
				  HYDROMASSAGE BATHTUBS
SECTION E4202.1 GENERAL.
Wiring methods used in conjunction with permanently installed
				  hot tubs that are installed in corrosive environments described in Section
				  E4202.2.1 shall comply with Table E4202.1, Sections E4202.2 and E4205, and
				  Chapter 38 of this code except as otherwise stated in this section. Wiring
				  methods used in conjunction with hot tubs that are not installed in
				  noncorrosive environments shall comply with Chapter 38 of this code.
				  Hydromassage bathtubs shall comply with Section E4209. (680.7; 680.14 (A) and
				  (B); 680.23(8) and (F); 680.25(A); 680.42; 680.43; and 680.70)
SECTION E4202.2 CORROSIVE ENVIRONMENT.
Areas where sanitation chemicals are stored, areas with
				  circulation pumps, automatic chlorinators or filters, open areas under decks
				  adjacent to or abutting structures, and similar locations shall be considered
				  to be corrosive environments. The air in such areas shall be considered to be
				  laden with acid, chlorine, and bromine vapors or any combination of acid,
				  chlorine, or bromine vapors; and any liquids or condensation in those areas
				  shall be considered to be laden with acids, chlorine, and bromine vapors, or
				  any combination of acid, chlorine, or bromine vapors. (680.14 (A))
SECTION E4202.2.1 WIRING METHODS.
Described in Section E4202.2 shall be listed and identified
				  for use in such areas. Rigid metal conduit (RMC), intermediate metal conduit
				  (IMC), rigid polyvinyl chloride conduit (RNC), and reinforced thermosetting
				  resin conduit shall be considered to be resistant to the corrosive environment
				  specified in Section E4202.2. (680.14 (B))
