Hello… Again…
Can someone advise as to the possible age of this square D panel based on this
mod and Serial number?

Type Q0 breakers
Mod QON-16M
Ser number: NOP 758824

I’m thinking pos’ 1975?

Has a floating panel cover
Thanks in advance

Why would you ever need to know the date of manufacture of a panel? If it’s deficient, report it!

Just for S&G’s… http://en.wikipedia.org/wiki/Square_D

4point on a 1960 house
Appears the panel is an upgrade per realtor.
Trying to determine year as best as I can for the 4 point.

Note: The serial number you posted is deceptive and incorrect. As shown in your pic, it is: P758824
With that in mind, the formula listed here: How do I determine a Square D Electrical Panel Age
…would make it approximately 1986 manufacture… but take all unqualified opinions for what they are worth, and with a grain of salt!

Was there a permit for this change out?
What about the debris in the panel, either paint or texture? Did you write that up?

Why don’t you call the manufacturer?

Thanks
There was some texture in panel, but I can def’ tell this panel is not the orig’ panel, as I could tell the orig’ panel was bigger due to indent in wall left behind.
I will call the company.
Thanks to both of you
