Name HW Due 530/19 ART 430, 440 1. The motor disconnecting means is not required to be in sight from the motor and the driven machinery location, provided_ (a) the (b) the provisions for locking are permanently installed on, or at, the switch or circuit breaker used as the controller disconnecting means (c) locating the motor disconnecting means within sight of the motor is impractical or introduces additional or increased hazards to people or property (d) all of these controller disconnecting means is capable of being individually locked in the open position 2. The disconnecting means for the controller and motor must open all ungrounded supply must be designed so that no pole can be operated independently. (a) True conductors and (b) False The motor disconnecting means must whether it is in the open (off) or closed (on) position. (a) plainly indicate (b) provide current (c) be in the upper position (d) none of these e than one motor disconnecting means is provided in the same motor branch circuit, only one af 4. Where mor the disconnecting means is required to be readily accessible. (a) True (b) False 5. The motor disconnecting means can be a (a) circuit breaker (b) motor-circuit switch rated in horsepower (c) molded-case switch (d) any of these (d) locked-rotor current (c)amperes (a) horsepower (b) watts 7. A horsepower-rated inverse-time circuit breaker can serve as both a motor controller and disconnecting means if (a) it opens all ungrounded conductors (b) it is protected by an overcurrent device in each ungrounded conductor (c) it is manually operable, or both power and manually operable (d) all of these 8. Article 440 applies to electric motor-driven air-conditioning and refrigerating equipment that has a herm refrigerant motor-compressor. (a) True (b) False 9. The rules of_, as applicable, apply to air-conditioning and refrigerating equipment that do not incorpo hermetic refrigerant motor-compressor (a) Article 422 (c) Article 430 (d) all of these (b) Article 424 10. Equipment such as_ are considered appliances, and the provisions of Article 422 are applicable in ado to Article 440 (a) room air conditioners (c) drinking water coolers and beverage dispensers (b) household refrigerators and freezers (d) all of these

11. A disconnecting means that serves a hermetic refrigerant motor-compressor must be selected on the bass of the nameplate rated-load current or branch-circuit selection current, whichever is greater. It must have an ampere rating of at least percent of the nameplate rated-load current or branch-circuit selection current whichever is greater (a) 125 (d) 115 (b)80 (c) 100 12. For cord-connected equipment such as, a separable connector or an attachment plug and receptacle is permitted to serve as the disconnecting means. (a) room air conditioners (c) drinking water coolers and beverage dispensers (b) household refrigerators and freezers (d) all of these 13. The disconnecting means for air-conditioning and refrigerating equipment must be from the a conditioning or refrigerating equipment. (d) a and b (a) readily accessible (c) a or b (b) within sight 14. Disconnecting means must be located within sight from and readily accessible from the air-conditioning or refrigerating equipment. The disconnecting means is permitted to be installed the refrigerating equipment, but not on panels that are designed to allow access to the air-conditioning or refrigeration equipment. (a) on air-conditioning or (d) none of these (c) a or b (b) within 15. Short-circuit and ground-fault protection for an individual motor compressor must not exceed_percent of the motor-compressor rated-load current or branch-circuit protection current, whichever is greater (a) 80 (d) 250 (c) 175 (b) 125 16. The rating of the branch-circuit short-circuit and ground-fault protection device for an individual motor- compressor must not exceed_ percent of the rated-load current or branch-circuit selection current, whichever is greater, if the protection device will carry the starting current of the motor. (a) 100 (d) none of these (b)125 (c)175 17. Branch-circuit conductors supplying a single motor-compressor must have an ampacity not less than percent of either the motor-compressor rated-load current or the branch-circuit selection current, whichever i greater (a) 125 (d) 80 (c) 250 (b) 100 18. Conductors supplying more than one motor-compressor must have an ampacity not less than the sum of the rated load or branch-circuit current ratings, whichever is larger, of all the motor-compressors plus the full load currents of any other motors, plus_ percent of the highest motor or motor compressor rating in the gro (a) 80 (d) 100 (b) 50 19. A hermetic motor-compressor controller must have a_current rating not less than the respective nameplate rating(s) on the compressor (a) continuous-duty full-load (d) a and b (c) a or b (b) locked-rotor 20. The rating of the attachment plug and receptacle must not exceed at 250v for a cord-and-plug connected air conditioner (a)15A (c) 30A (d) 40A (b)20A
