I am trying to put a handle padlock attachment on an FY breaker, but I do not know what series of breaker I have. How do I tell whether to use the HPAFK for Series 2 FY breaker; or the HPAFYQ for Series 1 FY breaker? <br />

The series number should be plainly listed on the breaker, either on the faceplace or on the side. If not, if the breaker is newer than 1/92 it is a series 2. Use HPAFK for a Series 2 FY breaker. If it is older than 1/92, use HPAFYQ for a Series 1 FY breaker.
