But in adding lines, you probably will run conduit and the electrician will run 4 wires for 2 lines, red, green, white and black. In my old house that's what I did and had zero issues and it was my best tweak by far.4 wires, black, red, white, and green. What you have described is 2 separate circuits, a multi conductor branch circuit, not 2 dedicated circuits. Each hot 120V conductor shares the same neutral conductor. Each hot conductor must be connected, one hot to a single pole breaker on L1 the other hot conductor to a breaker on L2. In this case only the unbalanced load of the two 120V separate circuits will return on the common neutral conductor. The balanced load of the two separate circuits are in series with one another. In other words any ac noise from one separate 120V load will flow through the loads on the other separate circuit.
When installing true dedicated circuits,
(1) hot conductor
(1) neutral conductor
(1) equipment grounding conductor.
Each dedicated branch circuit shall have its own equipment grounding conductor as per NEC. If you choose to tie all the equipment grounds together at the load ends of the branch circuits you can do so as per NEC. Some times in the case of long runs of dedicated branch circuits this will help if ground loop problems exist.
