Can you replace double pole with two single poles?
You can. But. Some contactors are wired up to control the on off of crank case heaters. So you have to watch that you don't wire them up wrong. Actually. More of a chance of something going wrong with a 2 pole contactor. Then a single pole contactor.But you can use a 2 pole in place of a single pole.
Can a single pole breaker go bad?
Breakers go bad, whether they are a Single pole or double pole. Just because you have two poles on a breaker, one pole can go bad, while the other still works fine. Even more fun, when you have a 400amp breaker blow, causing the other phase to blow out that side. Nice fourth of July action. Nothing to do with Ohm's law.
How do you wire a single pole breaker?

What is the Difference Between a Single and Double Pole Breaker?
The difference between a single pole and double pole breaker li es in voltage, amperage, and how they are wired.
how to wire a double pole breaker?
Well, as said earlier, one difference between a single pole and double pole breaker is how they are wired. In the following, we will examine the double pole breaker wiring.
How does a double pole breaker work?
In a double pole breaker, the electric panel, where the power comes from the transmission line, is wired to each circuit in the house. The line voltage is more or less limited by a transformer mounted on the power pole. This is often reduced to 220 volts from wire resistance and other factors. This energy reaches the house as two hot wires with the output voltage of the transformer between them. Each hot wire is attached to a hot bus bar and a third bus – the neutral bus – is connected by a third wire to the transformer. The voltage between any hot bus and the neutral bus is 120 volts, and the voltage between the two hot buses is 240 volts.
Why do you need a different breaker for each wire?
Each wire requires a different breaker because if the other one is operated, the other must still cut the circuit, otherwise, the wire stays carrying current. Circuits of a double-pole breaker have more power and that’s why it is rated for higher currents. In a double pole breaker, the wires are fatter than a single-pole breaker.
How many volts are in a 240 volt circuit?
All legs have 120 volts, but over the two heating legs, there are 240 volts, which is twice as much as 120 volts. A circuit breaker must be connected to each 120-volt leg to safeguard 240-volt devices.
