Hi guys- I want to add a receptacle 6 feet above an existing receptacle for a flat screen TV. I happen to have some 14/3 romex here, but no 14/2. As far as code goes, Can I pull the red wire out of the sheath - effectively turning my 14/3 into 14/2?

I want to install a standby generator at my house. It will be one of those Generac 16k units, LP fueled. I had arranged for an electrician to come out and do the work, and he was a no show. I have had no luck getting anyone else to be able to commit before winter, so I was contemplating taking on the initial install piece myself. Assuming I can arrange for getting a unit delivered and set on a concrete pad, I need some help with some things, and then I'll hand it off to an electrician who won't have much work to do other than wire the transfer switch to the main panel, something I'd rather let a pro handle. But I feel if I can get a good feel for what materials I need to get all the parts and pieces in place, I would like to try doing the bulk of the work. The generator will install on a pad that is next to a pedestal where the LP feed has already been trenched and mounted. So at this point all I need from propane tech is the final connection from their regulator to the generator once its in place. As far as electrical, I have an 2" underground conduit coming up behind the pad location. This conduit runs underground approximately 30 feet and comes up next to the outside wall of my garage, which is attached to the house. So my first question is needing to know what type of wire I need to run through this conduit to attach to the generator, and I would assume I'd have some type of electrical box on the garage side to terminate this wire. Then I would assume I'd need a 2nd wire to run from this connection box up and over the garage trusses across the garage and down into the utility room inside the house where the main panel and future transfer switch are located. If that assumption is correct, what type of wire would this involve? From here I'd just bring the wire that will connect to transfer switch into the house and then I'd let a licensed electrician do the rest. Am I missing any steps or do I need to do something differently? To summarize, I basically need to know what wire to run through the underground conduit from generator, what type of mounting box would I attach to side of garage to join the underground wire with the wire running inside the garage down into the transfer switch. Any help would be greatly appreciated.
