Can anybody help identify the rating of this Murray meter box? My (30-ish) client is an electrician, and he has never seen one. I do not recall seeing this exact design either. We are both assuming it is a 60 amp box, with a 200 amp digital meter, feeding a 100 amp fuse panel, circa. 1956, located in basement.
(Note: Wood enclosure prevented removing panel cover without damage. Barely able to get door open, so no inside pic’s).
Thanks in advance.
