If the centrifugal switch does not open at 70 to 80 percent of synchronous speed, it is important to have it repaired or replaced.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: Damage to the starting winding. This is the correct answer. If the centrifugal switch does not open at 70 to 80 percent of synchronous speed, the starting winding will continue to be energized, which can cause it to overheat and be damaged.<\/li>\n<li>Option B: Damage to the centrifugal switch. This is not the correct answer. The centrifugal switch is designed to withstand the high current that is flowing through the starting winding when the motor is starting up. If the centrifugal switch is damaged, it is usually due to a manufacturing defect or a problem with the motor.<\/li>\n<li>Option C: Overloading of running winding. This is not the correct answer. The running winding is designed to carry the full load of the motor. If the centrifugal switch does not open at 70 to 80 percent of synchronous speed, the starting winding will continue to be energized, but this will not cause the running winding to be overloaded.<\/li>\n<li>Option D: None of the above. This is not the correct answer. Option A is the correct answer.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on
