NOTE 2: The date codes listed above are used to identify the year and week of manufacture; i.e., 8430 indicates the thirtieth week of 1984, and 8636 indicates the thirty-sixth week of 1986. These date codes may be found on the top, side, or bottom of the circuit breakers.

NOTE 3: As an example, the unit may have the additional date code of R8642, where "R" designates a retest by Mechanical Products, 86 indicates the year 1986, and 42 indicates the 42nd week of 1986.
