I'm rebuilding my deck over Thanksgiving, and plan to upgrade the outdoor electrical features, as well (better lighting, more outlets - so I can have more POND TOYS!!!)
1. I already have electrical 12 ga wire - the kind with the black, white, and ground wires enclosed together in a flat white plastic sheath, which I assume is interior grade.
Now I've learned that there is special wire graded for "Outdoors." Since my wire will be run through metal conduit between junction boxes, will it be OK to use my interior grade wire for my outdoor project, or do I have to use "Outdoor" grade?
2. I want to install a better light outside my back door. The existing electrical box is rectangular. But the new light has a round base and fits a round junction box. Is there some way I can afix a round box to the existing rectangular box, without removing the whole thing? I'd like to add an extension of some kind, not rip into the siding of the house and the wall and remove the existing rectangualr box.
Thanks.
I looked on line, but could not find answers to my questions. I found another guy with the same exact problem as my #2, but the responses didn't seem to understand what he was trying to do, so I don't think he got correct information.
Thanks
