From what I understand, my building was built in the 40's and updated in the late 90's (new means 1996, not 2006). They ran new romex but kept the old fuse panels for some reason (former owner/landlord was cheap, had to get it up to date to sell). I opened the fuse box and there are grounds and neutrals in there. The noodle/ground bus seems original too, but it's maxed out (4 circuits).

I have no problems with fuses, and I haven't blown one yet, but my family doesn't always get it when I tell them why they can't run the hair dryer in the bedroom with the A/C running... among other stuff.
