Use only AWG # 10 copper.
No, you cannot use an existing 8 3 wire hooked to a 30amp breaker for a heater that requires 10 2 wire. The wire gauge and breaker size need to match the specific requirements of the new heater to ensure safety and proper function. You will need to upgrade the wiring to accommodate the 10 2 wire needed for the 5000-watt 240-volt heater.
For a 100' run from the panel to the RV using a 30amp breaker, you should use 10 gauge wire to ensure safe and efficient power delivery. This wire gauge is appropriate for the distance and the current capacity of the breaker.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
Check the MFG for the amps it uses, if it is suppose to be on a regular 20amp line, then replace the breaker with a 20amp breaker. With the 30amp breaker,it will work, but if there is a surge, you could send too much power to the appliance and fry it. Most refrigerators, are just on a regular 120v household outlet. Besides a 30amp breaker must have 10ga wire, if the wire is 12ga,it can not be attached to a 30amp breaker.
The minimum size wire a 20 amp breaker needs to be connected to is a #12 wire. The 15 is probably connected to a #14 right now which is only rated for 15 amps. Remember the breaker is sized to the wires ampacity not the load .

Read the literature for the ac condensing unit, or the tag on the outside of the unit. Minimum circuit ampacity= minimum breaker, wire and fuse size. Maximum circuit ampacity= the maximum size. Your circuit breaker, wire size and disconnect fuses should all be at or between those 2 numbers.
The recommended wire size for a 50 amp breaker is typically 6-gauge wire.
