Electrician question?

[14holestogie]

I am no electrician, but I've done some in my older homes.

You can replace the 2 prong plugs with 3 prong plugs, but if only 2 strand wire was used originally, the only advantage would be you could plug in the newer grounded plugs. The outlet itself would not be grounded unless 3 wire cable was used and would still be unprotected.
