In wiring for 220v can one use 2 15a breakers instead of a ganged 30a breaker?

Yes, you just have to be sure you are grabbing power from each of the two legs.

Do some electrical breakers when they are tripped go into the off position instead of the normal tripped position I have a cutler hammer breaker that tripped but is in the off position?
Some breakers can trip totally off. If the breaker is continually turning off without a wiring issue, then the breaker could be going bad.
Can strong winds outside can trip the circuit breakers?
Strong winds can not trip a circuit breaker unless there is incorrect or loose wiring in your structure.
What makes a circuit go out without tripping the breaker?
For the entire circuit to go out, the breaker has to trip. The breaker tripping is what causes the loss of power to everything pulling power from that circut. Any single power surge at any point along the circut can cause it. If you have experienced what you are questioning, I suggest you have an electrician take a look at your wiring. You may have serious issues. Breakers a designed to protect the wiring from getting too hot. It's a safety feature for your appliances, your home and those who live in it.
Is a circuit breaker an alternative fuses?
Circuit breakers do the same thing as fuses. They interrupt current flow when a certain preset point is reached. The difference between circuit breakers and fuses are that circuit breakers are resettable and reusable, whereas fuses are one time devices that must be replaced after they blow.
Is there any alternative for fuse in house wiring system?
Yes. Circuit Breakers.

Where to find a circuit?
Circuit breakers can be found in any circuit breaker panel. New circuit breakers can be bought at any shop that sells parts for installing or repairing electrical wiring circuits.

Strong winds can not trip a circuit breaker unless there is incorrect or loose wiring in your structure.
Circuit breakers are used for what?
Circuit breakers prevent excessive current from flowing in the circuit by "tripping" when the current exceeds the circuit breaker rating. This causes the current to be cut off, and is used to protect the wiring as well as the appliances.
What amp breaker do you need for a 325 watt heater 120 VAC?
Electrical breakers are sized by the conductor that is connected to it. The conductor is sized by the current that is drawn by the circuit. The formula for amperage is I = W/E. Amps + Watts/Volts. 325/120 = 2.7 amps. A #14 copper conductor is rated at 15 amps. This is the minimum size wiring that is used for house circuits loads. The breaker for this size wiring will be a 15 amp breaker.
What type of circuit is most common in household wiring?
The most common types of circuit breaker used are MCBs. (Miniature Circuit Breakers.)The most common type of breaker used in most every residence in the U.S.A. is the non-adjustable trip breaker.
Why is it important that homes have circuit breakers?
Fuses and circuit breakers are meant to protect your home's wiring from the heat generated from fault-currents and over-currents. Over-currents happen when you exceed the amperage the fuse or breaker is rated for over a period of time (IE: drawing 20 amps on a 15 amp circuit breaker). When this occurs a fuse or circuit breaker will open the circuit so the wiring in your home will not be damaged. Over-currents happen when electricity finds a path, other than the one intended, to ground. When this happens there is very little resistance to slow the flow of electricity and the amperage through the circuit can exceed the fuse or circuit breakers rated capacity by several hundred times . These type of faults cause the fuse or circuit breaker to open the circuit very quickly.
What does QP on a square D breaker stand for?
A QP type breaker is made by Siemens for a Siemens distribution panel and should not be interchanged with Square D. A Siemens QP type bolt in breaker will bolt into a SQ distribution panel but it is up to the electrical inspector to make the call as to it being safe or not. Square D breaker types are QO and QB. You might be mistaking the QP for a QB on the breaker. The QO breaker is a plug in breaker usually used in home wiring and the QB is a bolt in breaker. QB breakers are usually specified for industrial and commercial use.
What are the standard size circuit breaker amperages?
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.

Where do you connect the two leads of a shunt trip breaker?
Usually the breaker's shunt trip coil is tied to a corresponding current transformer that is sized to the amperage that is allowed to be passed through the breaker. These types of breakers can also be connected into a distribution monitoring device. If the monitor detects a phase reversal or phase loss or voltage rise or drop the breakers shunt trip coil is remotely energized and isolates equipment down stream from the fault. Shunt trip coil circuits are also used as safety circuits where the situation calls for only one breaker to be energized at a time. If the second breaker is inadvertently closed, this would allow both breakers to be on, the second breaker's auxiliary contacts that are an internally part of that breaker will close the safety circuit and energize the shunt trip in the first breaker to causing it to open. So as you can see the two wires could be part of many wiring configurations depending on what situation calls for.
