As far as your RV is concerned nothing is different. Yes you technically have up to 50 amps available at the adapter but the 30 amp circuit breakers in your RV's power panel will only allow you to draw 30 amps. When you plug your dog bone adapter into the 50 amp outlet the adapter taps only one of the two 110 volt legs and transfers the power to your power cord as though it was plugged into a 30-amp outlet. RVs with two air conditioners would have one connected to each 120 volt leg.
For example, all the kitchen outlets and appliances might be connected to leg one and the rest would be connected to leg two. The heavy duty cord jacket is made of a durable PVC coating that is strong and weather resistant. Manufacturers try to anticipate the power requirements and balance which outlets and appliances are connected to which leg. The Surge Guard 18' Male to Female Corded Adapter has (1) 30 amp male and (1) 50 amp female molded plug ends featuring Easy-T-Pull handles, making disconnect safe, fast and easy.
In an RV wired for 50 amp service some outlets and appliances are connected to one leg while other outlets and appliances are connected to the other leg. In an RV wired for 30 amp service all outlets and appliances are connected to the single 30 amp leg. (If you flip the breaker off, both are flipped at the same time) What that means is there are TWO 50 amp breakers, usually physically connected together, supplying the RV with current. The outlet is protected by a double breaker rated at 50 amps on each leg. Each power leg can supply 120 volts to neutral or the two can supply 240 volts from Leg 1 to Leg 2.
