Updating amps to condo building

reballen: in a commercial building i once worked in the DOB stated old knife blade switches on the main feed coming into the building were ok as they were grandfathered, but the insurance company told us they had to go. is that a possible route? for some reason, sometimes insurance companies ask to inspect a property. it happen to my neighbor on a small two family and they made him change some things.

also, now that i think of it, someone else i know was ordered to remove those old fuses but i think that was done by the lender during a sale. or maybe the insurance co?
