How do you keep corrosion off the copper terminals in a circuit breaker box?

If you have corrosion problem then you also have a moisture problem. Clean up the corrosion problem first before the resistance of the connection causes heat and wire burn off. Once cleaned, there is a product on the market that can be sprayed on to the connection which will create a barrier to the moisture laden air. Once this barrier is in place the problem should be resolved. An effort should be made to remove the moisture from the air, maybe with a dehumidifier.

Can a double pole 20 amp breaker be used with 12-2 wire for a single 220 circuit?
The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
What is the minnimum size equipment grounding conductor required by the NEC for a branch-circuit protected by a 50-ampere rated circuit breaker?
#10 copper
What kind of circuit breaker should you use with aluminum wire?
Almost all circuit breakers are rated for copper (cu) or aluminum (al), there is a label on every breaker made, as long as it has the (al) marking it is suitable for use with aluminum wire
What size of electrical wire needed for 100A circuit breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated for 105 amps.
Will it hurt to use a 40 amp breaker on a water heater the wire I was sold will not fit into the 30 amp on a sq. D circuit breaker?
In the United States, if the wire is #8 copper or larger (smaller number) it will work fine on a 40 amp breaker. If the wire is #10 copper, there is something wrong with the breaker if it does not fit. Pull the breaker out of the panel and look into where the wire terminates to see why the #10 wire won't fit.
What cleans corrosion off battery terminals?
Baking soda/water will neutralize. You can use a wire brush on terminals or one of those post cleaners with wire inside (if you have posts) Sandpaper works too. Also, if you put a copper penny between & can keep it there, the corrosion will attack it vs terminals.

What is the margin of safety with selecting circuit breakers?
The NEC requires that if the intended rating of a circuit corresponds to a standard size breaker then that size breaker must be used. In most instances, "rating of a circuit" means the intended connected load plus 25%. If the intended rating of a circuit does not correspond to a standard size breaker, you can go up to the next standard size without any other adjustments. In most circumstances, besides what I've already stated, a 14 gauge copper wire cannot be connected to a breaker larger than 15 amps, 12 gauge copper to a 20 amp breaker, and 10 gauge copper to a 30 amp breaker.
What is the minnimum size equipment grounding conductor required by the NEC for a branch-circuit protected by a 50-ampere rated circuit breaker?
#10 copper
What size wire and breaker do you need for a 200 amp continuous duty circuit?
AWG 2/0 copper wire.
What kind of circuit breaker should you use with aluminum wire?
Almost all circuit breakers are rated for copper (cu) or aluminum (al), there is a label on every breaker made, as long as it has the (al) marking it is suitable for use with aluminum wire

What size amp circuit breaker should be used for a gas dryer?
Typical residential electric dryers are on 30 amp circuits, which means 10 gage copper wire. The circuit breaker should match the dryer cord rating, generally 30 amps.

What makes copper rusty?
corrosion
Why is a gold coin shiny?
it is coated in copper. copper prevent corrosion.
How many outlets and lights on a 60 amp breaker?
120 amps The above answer is wrong. A 60 amp breaker is designed to trip at 60 amps be it a single pole, double pole or a triple pole that is used on three phase equipment. The number on the handle of a breaker is the trip capacity.
