At my parents' house, they have a 240V 30A circuit going to a regular interior 2-prong outlet. I have no idea what that would have ever been used for. I pulled off the cover plate and the two hot wires are connected to the plug, and there is a very thin ground wire in the box not connected to anything.
If I were to convert this to a 6-30 outlet, is that thin ground wire enough? If not, can I run a separate ground wire to the ground rod instead of back to the breaker box?
