Tomorrow, I need to let a client’s insurance company know the approximate year his electrical panel was replaced or he will be dropped. His home was built in 1959 and he is sure his panel was replaced about 20 years ago and that appears to be so because of the condition of the breakers and panel. It’s currently a Square D Panel with no replacement permit on file.
SQUARE D QO LOAD CENTER

STYLE NO. BEB36A
BOX CAT NO. QON24M125 Series G1
I called Square D yesterday and they got several people involved. They said the floating deadfront on the cover was released for production in 1981 so the panel has to be 1981 or newer. I have to redo his 4-point inspection and I’m afraid the 1981 date will still be too old for him to continue insurance with Citizens. I was hoping there would be a simple way like with serial numbers on A/C unites where the L8925xxxx in the serial number would mean something like the 25th week of 1989.
I did the inspection a month of so ago and while going back though my photos I wasn’t paying enough attention and thought the fan coil photo was part of the panel photos.
Thanks, checking the breakers for a date is a good idea. The home is a good distance from here so I may see if the client can get someone to check for a dated on the breakers in the morning.
The panel certainly doesn’t appear to be from 1959. It has Sq D Visi-Trip® breakers. Not sure when they came into the marketplace but it wasn’t 50+years ago.
The interior, box and trim will have individual date codes.It will be a 5 digit number located on the blue deadfront label under the Square D logo … Digits 1-2 = Year. Digits 2-3 = Week.
