Replacement for American Switch single pole 15 amp circuit breaker
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
3 pole circuit breakers are used for 3 phase lines
No, you cannot use one in place of the other.
is there an error if the upstream circuit breaker is 16A TP and the downstream circuit breaker is 16A TPN?
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.
3 pole would be for 3 phase, 4 pole would be 3 phase & neutral
before the load

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.
TPN means three pole with one pole neutral connected.
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.

Replacement for American Switch single pole 15 amp circuit breaker
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.
Yes.
