How do I determine the age of an Eaton electrical panel?
Saturday, March 27, 2021
Eaton load centers uses a five-digit date code that’s at the bottom of the data sticker inside the box at the side. First digit identifies which plant manufactured it, second digit is the year, third and fourth digits are the week, and last digit is a code for the decade. So the second and final digits are the ones you want to look for. To decode the last digit:
+ is 1980 – 1989
= is 1990 – 1999
& is 2000 – 2009
! is 2010 – 2019
@ is 2020 – 2029
# is 2030 – 2039
$ is 2040 – 2049
So the F618! code shown above means that it was manufactured in 2016 (sixth year of the 2010 to 2019 decade), on the 18th week. The code is in very small type and turned sideways. We recommend that you do not open the panel box to find the date code unless you are familiar with the safety precautions to take when opening a panel.
