If you have an old double outlet inside your home and you need to run a double outlet outside from this one How do you wire it?

The new receptacle has to be a GFCI receptacle. Try and locate the inside junction box on the outside of the house. The back of the old receptacle should have a 1/2 inch knockout in it. Remove it. Drill through the KO hole right through the siding to the outside. This will be the center of the new outside GFCI receptacle's junction box. Cut a new EZ box into the outside siding. Feed new wire 2C-#14 from the old box to the new box. Terminate both ends and replace covers. The new outside receptacle will need a weatherproof receptacle cover plate.

How do you extend romex wire you moved an outlet you need to extend and connect?

You need to splice the extension Romex, using wire nuts, inside a covered junction box made for the purpose. If you can do it within the original outlet box you can put a blank cover on the box. If not you may have to install a new "old work" box in wall. If you can get to wire in attic or basement you could put the junction box in one of those locations. The junction box must be accessible so you can't bury it in the wall.


How do you size a junction box?

There is no minimum height for junction boxes per NEC. Any use of a junction box that would be subjected to harsh conditions because of its height would have to be rated for the condition. Personally, in outdoor areas, I like to keep boxes at least 18" above grade in areas that get snow.
