45 Tests On Supply Cords
45.1 Flexing
45.1.1 An appliance In which intended operation of movable parts mechanically affects wiring or other insulated live parts. induding a supply-cord reel, shall operate successfully in the intended manner for the number of cycles specified in 45.1.2 while connected to a supply circuit in accordance with 37.1. There shall be no electrical or mechanical breakdown of the appliance and, after the test, the appliance shall comply with the requirements for dielectric voltage-withstand in 43.1.
Exception: If an interloc* switch de-er7ecgizes the wving or uninsulated live parts when flexed, the test may be conducted without energizing the sample.
45.1.2 The number of cycles otflexng is to be:
a) Fifty if flexing occurs only during installation or inspection of electrical field-winng connections.
b) Six thousand for a supply-cord reel or if flexing occurs only during regular prescribed
servicing — such as lubrication, resetting of protectors. or the like.
c) Thirty thousand if flexing occurs only during the compaction cycle — such as if a motor were mounted on a movable ram.
d) One hundred thousand if flexing occurs during loading or unloading of the compacting
con’ipartmerit.
45.1.3 In a test to determine whether an appliance complies with the requirement in 45.1.1. any mechanical arrangement may be employed to operate the movable member at a rate of approximately 12 cycles per minute. The movable member, it other than a cord reel, Is to be operated so that It will reach the actual limits of travel in both directions during each cycfe
45.1.4 To determine whether a supply-cord reel complies with the requirements in 45.1.1, the test is to be conducted with the supply cord not connected to the source of supply. Unreeling of the cord is to be arranged so that there will be a maximum tendency to abrade the cord insulation and wear parts in contact with the cord. The rectlon of tension on the cord during the test is to be in accordance with usage during normal service, The cord is to be unreeled 30 inches (762 mm) or more dunng the test and recoiled on the reel automatically. A latching mechanism may be disengaged to conduct the test.
45.2 Strain relief
45.2.1 The strain-relief means for a flexible cord shall withstand for 1 minute without displacement a direct pull of 35 lb-f (156 N) applied to the cord, with the connections within the appliance disconnected.
45.2.2 A 35-lb (16-kg) weight is to be suspended from the cord arid supported by the appliance so that the strain-relief means will be stressed from any angle that the construction of the appliance permits. The strain relief is not acceptable If, at the point of disconnection of the conductors, there is such movement of the cord as to indicate that stress would have resulted on the connections.
453 Push-back relief
45.3.1 To determine compliance with 12.1.1.12. a product shall be tested in accordance with 45.3.2 without occurrence of any of the conditions specified in 12.1.1.12 (a) — (d).
45.3.2 The supply cord is to be held 1 inch (25.4 mm) from the point where the cord emerges from the product and is then to be pushed back into the product. The cord is to be pushed back into the product in 1-inch (25.4-mmf increments until the cord buckles or the force to push the cord into the product exceeds 6 lbf (26.7 N). The supply cord within the product is to be manipulated to determine compliance with 12.1.1.12.
46 Overload Test On Switches
46.1 A switch or other device that controls a motor and has not been investigated and found to be acceptable for the purpose, shall perform acceptably when subjected to an overload test consisting of 50 cycles of operation, making and breaking the locked-rotor current of the motor. There shall be no electrical or mechanical breakdown of the device or undue pitting or burning of the contacts as a result of the overload test and the fuse in the grounding connection shall not open.
Exception: This requirement does not apply to a switch or other device intertocked so that it will not have to break the locked-rotor current of the motor.
46.2 To determine whether a switch or other control device complies with the requirement in 46.1. the appliance is to be connected to a grounded supply circuit of rated frequency and voftage in accordance with 37.1, with the rotor of the motor locked in position. During the test, exposed dead metal parts of the appliance are to be connected to ground through a 3-A plug fuse and the connection is to be such that any single-pole, current-ruptunng device is in an ungrounded conductor of the supply circuit, The device is to be operated at a rate of not more than 10 cycles per minute. except that a faster rate of operation may be employed with the concurrence of those concerned.
