4 Wire Split to 2 circuits 110v
My 3rd floor was pre-wired with one romex cable with black, red, white and ground wire. Black and Red wire are attached to seperate 15 amp breakers on the right side of the panel, adjacent to each other. I want to split them in to two seperate circuits. Red to a living room, black to a bed room. How do I handle this? Can I use attach the black wire to a plug and wire the bed room circuit from it and run the red wire directly to the living room circuit. How do I handle the 3 neutral wires?

Welcome to the forums!
That's a 4-wire, 3-conductor cable, and it's carrying 120V on the black and the red.
It is two separate circuits. Use 14-2/G cable (black and white wires, plus ground) to extend them. In a rated box that's large enough to hold everything, splice all of the grounds together and bond those to the box, it it's metal. Splice all three neutrals together. Splice the black from one of the 2-conductor cables to the black from the panel, and splice the black from the other 2-conductor cable to the red from the panel.
In the panel, is there one 2-pole 15A breaker protecting the 4-wire cable, or are there two single-pole breakers with their handles joined with a handle tie?

You can't split to 110 volts because your house is 120 volts neutral to hot.
At the first receptacle you would have the 3-conductor cable from the panel and a 2-conductor cable to the next room.
Black of 3-conductor cable to the receptacle.
Red of the 3-conductor connected to the black of the 2-conductor.
All neutral to a pigtail. Pigtail to the receptacle.
All grounds to a pigtail(s). Pigtail(s) to receptacle and if metal box to the box.
Note the breakers must be handle tied (or a 2pole breaker) and on opposite legs of the 240v.

All White Wires in the wire nut? Or just the power in and bypass circuit
In my diagram I planned to wire nut the white attached to the box, the circuit going to the next room and a pig which will attach to the receptical. The black and white wire going to this room would attach to the receptical also.
Is this correct?

Thanks
Thankyou so much for your review and comment. I had seen something like the diagram I drew, but wasn't sure I remembered it correctly.
I will give it a try on Saturday.

You should have a second splice with the three incoming white wires plus one pigtail for the receptacle.
You should also have a third splice, with the incoming black wire, the black wire going to the living room and a pigtail for the receptacle in it.
Finally, you should have a fourth splice connecting the red wire to the black wire going to the bedroom.
I hope you have a nice deep box to hold all of this.
There are two single pole breakers.

See revised diagram.
All ground wires will be spliced together with a pig attached to the receptical in this box.
The ground is what I am still struggling with.
In my diagram I had intended to attach the power source white to the white going to the bed room circuit (The hot red to the black for the bed room) with a pig attached to the receptical. The white wire for the living room was going to be attached to the other receptical screw thereby connecting them.
If I connect all three white wires in this plug box will all of the other plugs and lights on the living room circuit have the nuetral?
The hot black wire would also attach to the receptical, with the black for the living room fed off the receptical.

I am torn betweed the first and second diagram methods. The latest connects all neutral wires with a wire nut and connects to the first plug via a pig.
The first connects two nuetral wires with a pig to the plug, but then the neutral for the other circuit is connected to the plug.

You've got it right in your revised diagram. This pigtail should, of course, be made with a piece of white wire.

White connection to the box refers to the connection to the neutral bar on my breaker panel?

There is one important question we haven't seen your answer to yet: Do the two single-pole 15A circuit breakers have their handles joined by a handle tie, or will they?

Thanks everyone.
SUCCESS!
Yes I did mean the neutral (white) wires when I was still not sure.
I have completed the wiring and it works as expected. Using a multi-meter all plugs and lights register about 118 volts +/- .3. This is also what I get at the breaker.
