Just because your fuze box has been updated with a new panel does not mean the wiring has been updated. When a service change has been made, the code does not dictate that the rest of the branch circuits in the home also needs to be updated as it would be very expensive.

The issue here is the wiring, not the service. If you have clothing wiring; you dont have a ground wire as there is only 2 wires available (you may have metal boxes but that doesnt mean they are grounded) (also you may have BX cable but may not be rated as being used as a ground conductor.

If your interested in looking it up in the NEC code it is Article 406.3 (3)

The code specifies that only when something is updated (like wiring in the walls or new circuits) shall be updated with current codes. if it is existing its fine.
