We moved into a new house that only has an old NEMA 10-30 outlet for the clothes drier. I'm tempted to update it to a 14-30 by running a new ground from the subpanel.
We bought a drier and it came wired for 14-30. Conversely, I could just rewire the drier itself back to a 10-30 by using some kind of ground/chassis bonding, apparently.
I've done basic electrical but never tried to just run a 30A ground from the sub. If I went that route should I use 10 gauge NM? I don't even know if I could fish it from the sub to the outlet; I'm probably looking at cutting away drywall and then having to patch/replace (which I've never done before).
So if it were you, and you were trying to decide between the hassle involved in updating the outlet and messing with drywall, plus the effort of running a new 30A ground from the subpanel vs. rewiring the drier for the older 10-30, what would you do? I don't understand how dangerous it is to take a 14-30 drier and switch it back to 10-30. Any thoughts / suggestions?
