22,1 When motor protection that is evident to the installer or user is furnished as part of a dispensing device, it shall provide protection under both stalled rotor and overload conditions.
22.2 A tag shall be attached to the motor circuit wires indicating the voltage from which the motor is intended to operate, in the case of motors of single voltage rating; or the voltage br which the motor has been connected, In the case 01 motors for dual voltage rating.
23.1 A switch shall be rated for the maximum load that ii controls.
23.2 A motor switch shall have a sufficient number 01 poles to control the motor or motors. A single pole switch installed in either a lighting or motor circuit shall not be connected to the grounded neutral conductor.
24 Class I, Group D, DIvision 2 Location, Lighting, Electrical, and Electronic Equipment
24.1 Lighting, electrical, and electronic equipment utilized in Class I, Group D, Division 2 hazardous locations shall also comply with outdoor use requirements for such components and, unless of the weatherproof type, shall be in a raintight enclosure, see the Rain Test, Section 39; or shall be otherwise protected to reduce the nsk of water entering a lamp holder or the enclosure for electrical and electronic equipment.
24.2 A lamp holder shall be an unswitched type. A lamp holder for a incandescent lamp shall be not larger than a medium base type. A lamp holder for an electric discharge (fluorescent) lamp shall not be of the combination type including a starter holder.
24.3 A lamp holder shall be mechanically supported and shall be wired in the assembly at the factory.
24.4 lighting, electrical, and electronic parts other than lamp holders which may produce arcs or high temperatures shall be in an enclosure complying with the requiemenls for Class I, Group D equipment for use in hazardous locations specified in the National Electrical Code. ANSINFPA 70.
24.5 lighting, electrical, and electronic parts other than lamp holders which do not produce arcs or high temperatures when operated as intended and which are located in the Class I, Group D, Division 2 hazardous location may be in a general purpose enclosure. Such enclosure shall be of metal and shall be of the total enclosed type or constructed to reduce the risk of escape of sparks or hot metal particles.
24.6 The requirement specified in 24.5 is not intended to preclude the use of small areas of glass or plastic in a Class I, Group 0, Division 2 hazardous location, where such material is required for the transmission of price and volume data, instructional information, or both. The use of nonmetallic materials shall comply with the following:
a) The total area of nonmetallic material that Is not backed up by metal panels shall not exceed 150 square inches (645 square millimeters);
b) A glass panel shall be at least 3/32 inch (2.4 mm) thick;
C) A plastic panel shall comply with Materials, Section 5;
d) The construction shall be such that breakage of the nonmetallic panel will not permit sparks or hot metal particles to enter a Class I, Group D, Division 2 hazardous location.
247 Lighting, electrical, electronic equipment, and wiring in a Class I, Group D, Division 2 hazardous location must be completely sealed off from a gasketed joint, hose, stuffing box, or hose nozzle boot In or above the Class I, Group 0. Division 2 hazardous location by means of a solid partition or enclosure.
24.8 A lighting fixture intended for mounting on a dispenser shall comply with the Standard for Electric Signs, UL 48 The dispenser and lighting fixture shall include means for secure mounting of the fixture and to reduce the risk of water entering the conduit system of the dispenser.
25 Wiring Methods
25.1 The wiring of circuits within the device shall comply with the requirements specified in 25.2 — 25.24. Splices in conductors shall be insulated and positioned to reduce the risk of high voltage parts contacting metallic parts of the dispensing device.
25.2 Conductors Intended for field connection to a 1 20-volt branch circuit protective device shall be provided and arranged such that an individual grounded neutral conductor is provided for each ungrounded supply conductor.
25.3 Except for intrinsically safe circuit rated not more than 30 volts ac (42.4 volts peak), the internal wiring of the device shall consist of wires of a type or types that have been successfully evaluated for use with respect to the temperature, ampacity, voltage and conditions of service to which the wiring may be subjected. See 21.15.
25,4 WIring resistant to fuels may be exposed to vapors of the fuels (not liquid fuel) at temperatures within the limits of the temperature rating of the wire type.
