But in order to be courteous to other campers and the campground, if there is a 50 amp receptacle for your 50 amp plug definitely use it. You likely won’t know until you have to try it. This could strain your appliances and ultimately break them.ĭetermining just how much you can run, especially while using an air conditioner or heater, on your limited power supply is not easy. When you plug your 50 amp plug into that 30 amp receptacle, expect only one-third of the amount of power you are used to getting. That is over three times the power supplied by the 30 amp plug and receptacle. As we saw above, 30 amps are 3600 watts or 30 x 120. The discrepancies lie in the fact that the amps to power or watts aren’t exactly proportional. If this happens, the 30 amp receptacle could burn up and become unusable something that is likely to upset the campground owner. It isn’t always safe to assume the campers breakers will trip either. If you use too many you will be bogged down, not only in your rig but those hooked up to the same circuit and could even overload the campgrounds electrical system. If you are used to having 50 amps worth of power, and your RV is designed to run on this amount of electricity, it can be difficult to determine how many appliances you can use on a lesser amount. So why are campground owners so concerned about plugging in plugs with different amperages than there receptacles by use of an adapter? Because you will be drawing a lot of electricity from that lower wattage circuit. What Concerns Are There When Using an Adapter? You will have less electricity available to consume and will have to be savvy about what you are running and when. If you plug a 30 amp plug into a 50 amp receptacle with an adapter, you still receive 30 amps, your rig doesn’t magically become a 50 amp system.Īdditionally, and importantly, if you plug at 50 amp plug into a 30 amp receptacle with the assistance of an adapter, your RV only receives 30 amps or 3600 watts. However, this doesn’t necessarily mean that the flow of electricity increases or decreases. Adapters can be used to plug a 50 amp plug into a 30 amp receptacle and vice versa. Then there is a neutral prong and a ground wire. This is because two of the prongs are each 120-volt transmitter and each supply electricity to their own “main” lines. It has been mentioned that a 50 amp plug has four prongs. Therefore, if you tend to run a lot of appliances simultaneously or have a bigger RV you will likely be equipped with a 50 amp system. This uses a four-pronged plug and must be hooked up to the appropriate 50 amp receptacle.Ī 50 amp set up can provide 12000 watts of electricity, much more than 3600 watts of a 30 amp system. If you have a bigger RV, especially one with more than one rooftop air conditioner or residential-sized appliances ( like washers, entertainment systems, and refrigerators) you will need a 50 amp electrical system. On this system, you can expect an RV to have multiple outlets, a television, one rooftop air conditioner, a microwave, and a refrigerator. These are popular with small to moderate-sized RVs that don’t typically draw a lot of power. For the purposes of this post, we will be looking at 30 amp systems and 50 amp systems as possible power sources.ģ0 amp systems use a three-prong plug to distribute 30 amps or 3600 watts of electricity to your rig. Having a host of appliances in your RV means that you will need an energy source to run them.
