You would need a 20 amp switch when the load controlled by the switch can draw as much as 20 amps. If you have a 20 Amp breaker supplying the circuit then you need to size all switches and outlets on that circuit to 20 amps.
If the wire to the switch is AWG #12 you need a 20 amp switch because it is a 20 amp circuit.
Yes, what you are looking for is a double pole double throw switch. The center lugs are connected to the incoming line. Then the top lugs could be connected to the electric heater and the bottom lugs connected to the condenser. The trouble lies in finding a switch with a rating of 20 amps. These types of switches are usually used with a stand-by generator and rated at 100A and greater. Think I remember seeing one at 60A once. You might want to think of using a DPDT relay rated at 30A with a 120 volt coil. With a switch to operate it the relay. Depends in what part of the country you live, long winters switch off for heater, long summers switch off for conderser.
No, they each need their own breaker of the right amp. Neither of them would cause the breaker to trip if there was a problem.
The switch would be open.
If a single pole switch is wired to be a master switch, the switch would have to be in the on position for any other control devices to operate. Turning the master switch off would eliminate power to all devices (and/or loads) which it was serving. For example, some homes have a switch to control their outside light. If the outside light has a photo eye (the light will only come on at night), the switch is the master switch. Another example would be the breakers in an electrical panel. Each breaker would be the "master switch" for the circuit it protects. The main breaker in the panel would be the "master switch" for the entire home.
If the wire to the switch is AWG #12 you need a 20 amp switch because it is a 20 amp circuit.
because it would be easier

It would have been a lot better.
The fan motor has probably failed.
Ck fuse number 18 in the IPM.That would be under the hood and it is a 20amp fuse.
because zac has got beuatiful eyes!!!!
Yes it would because they have the same ingredients in them
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
it would be an adverb because it would not be describing a noun as what an adjective would do but insted it is describing a verb so i think it would be an adverb
It would be very slow going and the walls would be very thick.
I think its singular i know its wierd but would it be the most insted of just most.
