How do I determine the age of a Siemens electrical panel?
Saturday, March 27, 2021
Most Siemens load centers have the date of manufacture stamped in ink on the back of the panel box near the bottom as shown above. In some panels, the date may be emboosed in the metal instead of stamped in ink. The date may be partially concealed by wiring in the panel. We recommend that you do not open a panel to look for the date stamp unless you are familiar with the necessary safety precautions.
Siemens panels from the 1980s to early ‘90s may have a small stamp near the top of the data sticker, like this one from 1988.
Also, some newer Siemens panels have the manufacture date stamped on the data sticker on the inside of the panel door, like in the photo below.
