Can you convert a 240V circuit on your service panel to two 120V circuits?

A 240 volt breaker can be removed and replaced with 2 - 120 volt breakers.

The existing 240 volt breaker should not be used to supply 2 separate circuits.

In electrical trade terminology, the use of the word "sub", as in sub panel, refers to an auxiliary distribution panel that is fed from the main distribution panel.The circuits from a sub panel can be named the same as the circuits from the main distribution panel. A circuit name is usually named after the device that the circuit connects to.For example, range circuit, hot water tank circuit, lighting circuit, and so on.

You should always label the circuits in the panel you just installed.

The point where wires interconnect with other wires is known as a "junction". In your panel the circuit breakers are connected to the buss, each circuit breaker feeds a different circuit. Different circuits are not connected together.

Yes. You are allowed to use a neutral for one circuit from each phase of your service. For example, in a residential service, you can use the same neutral for circuits 1 and 3. In a commercial (3 phase) service, you can use a neutral for circuits 1, 3, and 5. You will experience problems if you use a neutral for two 'black' circuits or two 'red' circuits, if the circuits originate from the same phase bus bar. Also, AFCI's are sensitive to sharing neutrals, but GFCI's are not.
