I have one question related to my own home and one related to a project a friend would like me to help him with.
Question number one:
I'm planning on running a new circuit to my upstairs with just one outlet on it dedicated for use by a window air conditioner. I'm planning on using 12g and making it a 20A outlet, even though our current window AC model is very efficient and doesn't require this. I figure if I'm going to go to the trouble I may as well use the heavier guage for any possible future needs.
I happen to have an extra 20A GFCI outlet in my parts pile and I was wondering if I should use this or not. I don't know if this is recommend or not for window AC units, so I'd like to know what you guys think - GFCI or standard?
Question numero dos:
My friend recently had a new service drop and panel installed in his ~60 year old home. He has the old tar-paper insulated copper wiring with no ground still running throughout the house.
This is especially unerving in places like his kitchen, where he's been running items like his refridgerator and microwave that require a grounded circuit without any grounding. Actually, he had a range hood, coffee pot, AND his fridge all hooked up to a three-outlet expander that was in turn plugged into a two-to-three prong adapter.
If we were to run a few new circuits (I've been prompting him to run a seperate one dedicated to just the fridge), could we make use of the old outlet work boxes? In other words, could we disconnect and then cap off/insulate the old wiring and leave it unused but still present within the old work boxes, then run the new wiring in and make use of that with new outlets?
If not, what's the correct procedure for rehabbing old outlets? We could use new "old work" boxes, but this would be an extra hassle and in some instances look odd.
Any advice is appreciated guys!
