Kitchen Remodel (conduit and Wiring)
I'm about to embark on a kitchen remodel. The house is 1912 and has a lot of knob and tube and old AC with cloth insulation. I'm in Chicago so have to use pipe for everything. I have full access in the basement so will be running a 1" pipe around perimeter. While I have access to the stud bays, I will run EMT from the basement to the 2nd floor to replace existing recepticles and add new ones.
I have a few questions
As I don't have access to the end of any stud walls, running pipe between the studs would be a lot of short sections and connectors, so I figured I'd run vertical emt from the 1" pipe in the basement (lots of junction boxes).
is this a better method than running lots of short pieces? If I were to run between studs from box to box, would I run conduit at the center height of the boxes (so I come out of right side of one box, through a stud and into the left side of another box).
Can I just pigtail the wire to the recepticle in the JB on the floor joist? So I would cut the incoming wire, pigtail the wires for the recepticle (2-4 feet above) and also pigtail the outgoing wires to the next recepticle. Or, do I have to run the wire up to the recepticle, pigtail in its box and then run it back down?
As there will be many circuits in the 1" perimeter conduit, can other circuits pass through a jb where I make a pigtail. For example, the dishwasher and one of the small appliance circuits share the same run for much of the distance, so I would be running the dishwasher circuit through 3 jb's that have vertical runs to outlets above. Is it OK to pigtail the wires for the small appliance recepticles and have the dishwasher circuit pass straight through those JB's
