To find the age of an ITE load center (electrical panel), look for a 5-digit date code of a single letter followed by four numbers. The last two digits are the year of manufacture, and the 1st digit is the month, encoded as: A = January, B = February, C = March, D = April, E = May, F = June, G = July, H = August, J = September, K = October, L = November, and M = December. The 2nd and 3rd digits are day of the month.  You can find the code stamped on the wiring diagram sticker on the inside of the panel door. Hopefully it’s still intact all these years later. So, for example, B2685 (shown below) was produced on February 26, 1985.

    Gould acquired ITE in 1976 and, between 1976 and 1983, the panels were branded as "ITE Gould.” Then Siemens gobbled up Gould ITE in 1983, retired the name shortly after, and transitioned to their date system over the next few years, with some overlap between the two. See our blog post How do I determine the age of a Siemens electrical panel? for that date system.
