As a long time reader, but not often poster I have some questions regarding installing new wiring in house remodel.
1) I realize that junction boxes have to be accessible & this is where I have a problem. In running some new wiring I would like to replace the old sections of wiring (old cloth covered type - 60± yrs old) that are uncovered. This means splicing in the middle of the run. However, it would also be an area that is going to covered with drywall in a finished room so an access opening is not possible. The total run cannot be replaced since the wire runs up into other areas that are not being redone. I really kind of hate to just cover up the old wiring again with out doing something to better it. Is there some way to accomplish this?
2) in new construction there are requirements for fastening/securing wiring to joists, studs, etc., but evidently in remodeling where new wire is fished through walls and ceilings this is not a problem - other than fastening at boxes?
3) lastly, had an licensed electrician tell me that when running new wiring in basement that runs of gray pvc electrical conduit can be used for runs perpendicular to joists instead of drilling new holes in joists. Where wires exit to run with joists can put in a "T" for wires to exit from. For example have 2" pvc conduit run along outside perimeter of basement and have 7 or 8 20A wires loose in them then have exit @ a "T" to go where they have to go. Anyone heard of this before? Is it allowed? He installed my new 200A box that was permitted & passed inspection.
Thanks,
Rob
