50 amp - 30 amp

I have an 2003 International. The park Iím In didnít have a 30 amp receptacle so I put an adapter and plugged into the 50 amp service plug. Would this effect the cost of electricity?

No. Some will argue that an unbalanced load will cost you more but that does not apply to 120/240 volt residential service. Besides that you are still taking power from only 1 leg whether plugged into a 30 or a 50 so it's moot anyway.

If you do the 50 to 30 amp connector do you get 30 amps or 25 amps?

Hi

50A service is 50A at 240V. Each of the two legs is a 50A 120V leg. If you could, your adapter would get you 50A instead of 30A.

Compare the electrical to your water hose. Amps is quantity (in this case available), Voltage is pressure. The 50 amp rating is overcurrent protection, your circuit breaker. The circuit breaker is the gate keeper. It is best to match your load to the rating of the wiring, like 30 amp or 50 amp. It is okay if you use a 30 amp cable on the 50 amp service because at your RV the circuits have breakers. If you try to draw more than the 50 amp quantity all at once the 50 amp rated circuit breaker will trip. If you connect to high voltage there is too much pressure and it bursts your electrical stuff (lets the *smoke out). Watts is the way your consumption is measured so cost is based on what you consumed (electrical energy converted to work).
(*smoke is what makes all of your electrical stuff work. If you let the smoke out your stuff will stop working)
