A GFCI breaker monitors the imbalance of current between the ungrounded (hot) and grounded (neutral) conductor of a given circuit. With the exception of small amounts of leak-age, the current returning to the power supply in a typical 2-wire circuit will be equal to the current leaving the power supply. If the difference between the current leaving and returning through the current transformer of the GFCI exceeds 5 mA (61 mA), the solid-state circuitry opens the switching contacts and de-energizes the circuit. Touch the neutral or hot and you change this current which will trip the breaker.
No, a two pole GFCI breaker must be wired to both hot wires of a circuit in order to function properly. Using only one side will not provide the necessary ground fault protection.
No, a 2 pole breaker is designed for a 240-volt circuit or for two separate 120-volt circuits that are out of phase with each other. For a 120-volt single-phase circuit, you would typically use a single-pole breaker.
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
No, you cannot use two separate 15 amp single pole breakers in place of a double pole 30 amp breaker. A double pole breaker is designed to simultaneously disconnect both circuit conductors, whereas using two single pole breakers would not provide the necessary protection for the circuit. It is important to use the correct size and type of breaker as specified by the electrical code for safety and functionality.

Yes, the rating of a 3 pole circuit breaker is the same for each conductor that is connected to it. A three pole breaker rated at 30 amps will have 3 #10 wires from it that connect to the load.
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire

No, the three individual poles of a three phase circuit breaker are not electrically connected to each other. If they were, a fault would develop internal to the breaker.
You can use a 15 amp single pole breaker to convert your 30 amp double pole breaker to 15 amp 120v. Simply replace the 30 amp breaker with the 15 amp breaker in the circuit breaker panel. Make sure to match the wire size in the circuit with the appropriate amperage rating of the new breaker.
