If you worry about the RV park’s higher amperage rating potentially frying your 120-volt, 30-amp RV appliances, you can always get a dogbone adapter with a surge protector built-in. One of the prongs doesn’t even have a cable connected to it. On the other hand, a 30-amp to 50-amp dogbone adapter doesn’t have the “hot wire” cross bridging. It’s worth pointing out that a 50-amp to 30-amp RV adapter connects two “hot wires” at the 50-amp section. This arrangement allows you to convert 30 amp to 50 amp. However, you will need a different dogbone adapter – a 30-amp female connector and a 50-amp female connector. What if you parked your 30-amp RV in an RV park with only 50-amps of shore power? Can you plug a 30 amp into a 50 amp system? Plugging a 30-amp RV Into 50-amp Shore Power However, please understand that your maximum wattage draw will only be 3,600 watts, making it nearly impossible to run some RV appliances. So, if you ask yourself, “Can I plug my 50 amp RV into a 30 amp plug?” you know the answer. Moreover, the NEMA 14-50 female connector features bridged “hot wires” to convert the 30-amp outlet’s single “live” line into two. It has a NEMA 14-50 female connector to accommodate the 50-amp RV plug and a NEMA 14-50 male connector on the opposite side to plug into a 30-amp outlet. The adapter has two connectors on either side. It allows 120-volt electricity to flow into two “prongs,” a fundamental requirement of 50-amp systems. They differ only in the extra 120-volt prong in the 50-amp system.Īn adapter solves this issue by splitting the 30-amp system’s single 120-volt element into two. It’s worth noting that 50-amp and 30-amp systems have ground and neutral wires. This characteristic gives the 30-amp system a 3,600-watt maximum output (120 volts x 30 amps = 3,600 watts). Two are the neutral and ground wires, and another for the “hot” wire carrying 120 volts. While a 50-amp system has four prongs or holes, a 30-amp device will only have three. With 12,000 watts of power, you can run several power-hungry appliances (i.e., water heaters, ovens, refrigerators, and air conditioners). This system delivers 12,000 watts (240 volts x 50 amps = 12,000 watts). The other two prongs are the ground and neutral wires. Two prongs or holes are “hot” or “live,” each carrying 120 volts for a combined 240 volts. If we look at a typical wiring diagram for a 50-amp system, we’ll notice four “holes” in the outlet or four “prongs” in the plug. Let’s differentiate a 50-amp from a 30-amp system to appreciate the adapter’s function. A 50-amp to 30-amp RV adapter should do the trick.Ī 50-amp to 30-amp adapter splits the 30-amp outlet’s “live” or “hot” wire into two to supply sufficient power to the two “live” cables on the RV’s 50-amp system without damage or any untoward incident to either system. Unfortunately, some RV parks only have 30-amp outlets, making it problematic for 50-amp RVs. Hence, many RV parks provide shore power in 30- and 50-amp capacities. However, some power-hungry devices and machines need 240 volts or up to 50 amps of electricity. Most RVs feature 120-volt appliances requiring 30 amps of power.
