20.101 Switches installed in multi-position sockets should have sufficient making and breaking capacity. The test shall be carried out with the installation shown in Figure 12.101 and used to simulate normal operation. The switch shall be connected to the wires used for the tests in Chapter 19. The switch is usually tested at 1.1 times the rated voltage and 1.25 times the rated current. It is subjected to 200 operations at the following average rate: 30 times per minute if the rated current does not exceed 10A; 15 times per minute if the rated current is greater than 10A but less than 25A; 7.5 times per minute if the rated current is equal to or greater than 25A. For rotary switches intended for bidirectional operation, the operating element is rotated in one direction for half of the total number of operations and then in the opposite direction for the remaining number of operations. The test is carried out with an alternating current of cas#-0.6±0.05. During the test, no continuous arc shall occur: after the test, the specimen shall not have any damage that affects its continued use. ; One operation of a plug refers to one insertion and removal of its pin, and one operation of a switch refers to the movement of its moving contact from one operating position to another.
