How do I determine the age of a Murray electrical panel?

Tuesday, February 1, 2022

The date of manufacture of newer Murray panels—the ones produced since Siemens took over the brand in the 1990s—can be found at the bottom of the paper data plate on the inside of the panel door, as shown in the example above. But Murray Electrical was founded way back in 1899 and went through several changes of ownership before Siemens took over, including by Arrow Hart and Crouse Hinds in the 1970s. We are not familiar with how to determine the age of the older Murray panel boards. Siemens stopped producing Murray brand panels in 2019, but the panel design is compatible with Siemens circuit breakers.
