found a sub panel with a 3pole 50, 8 2pole 20's and a 2pole 30 amp breaker. it was fed from another panel, off the line side of a 150 amp main breaker. i haven't looked for the breaker that is feeding the feeder, but i should check it as well. it show's you what tenants will do to save money.
this was a before picture. it is a panel for the forklift chargers. the peice of iron was used for hanging the cords from the chargers and was bolted to the table. the equipment was relocated, so the panel was not needed anymore.
