Hello guys,
I need to run a new circuit from the panel in the basement to the kitchen upstairs. This will feed a dishwasher, hence I guess it must be dedicated for the dishwasher only.
The problem is that there is no clear path to reach the kitchen. What I have in mind, to do things easier, is to go from the panel to the outside wall and run a pipe/tube or anything to the desired location and enter to the house.
My question is... what material the pipe/tube should be? It's any normative that defines the section of this tube/pipe depending on the cable being run inside?
On the other hand, this path could help me to run another line (this time 220v) that would enter the house at the same point but will continue to the laundry room. Can 110 and 220V wires share the same tube/pipe?
Thanks in advance.

You can have several 120 and 240 volt circuits in same conduit. Only limit is wire fill.
Sometomes you can get from downstairs through a closet(out of sight)to an attic? And then drop down wall to new location. Takes about as long to run 3/4 inch instead of 1/2 inch. I would rin 3/4 PVC. If corrosion and rust not a problem or it is easier, you can use Metal Conduit.
