But a 50 amp RV has two legs of service going into the rig instead of just one. So if we multiply 30 amps times 120 volts, a 30 amp RV can consume 3600 watts of power at one time. Then you will know the maximum simultaneous power capability of any electrical system (the watts). It says that you multiply the amps times the total volts. So we can determine how much difference there is in consumable power between 30 amps and 50 amps by using a common electrical formula. The volts at the campground pedestal should remain at 120 volts no matter what RV is plugged into it. Why? Let’s take a look at a very useful electrical formula to understand why 50 amp RVs can do that. A 30 amp service will usually only allow the operation of one AC unit in the RV.īut a 50 amp service can run more than one AC unit and even provide plenty of extra power at the same time. The difference between a 30 amp and a 50 amp RV service becomes especially apparent when using air conditioners. It moves electricity along to the appliances in the RV.īut a 50 amp RV service can move a lot more electricity at the same time because the wiring is much larger and more capable. So in RVs, a 30 amp service is like the garden hose. There has to be some water pressure to move the water along.īut if you have a consistent water pressure, the fire hose will move more water than a garden hose. Volts are like the water pressure that goes into the hose. But a fire hose is much larger and therefore will put out a lot more water at the end. There are different sizes of water hoses, some big, some small.įor instance, a garden hose will put out a steady stream of water.
The best analogy I have heard to describe the relationship between amps and volts is to picture a water hose. And while we are at it let’s also do the same for volts too. To understand what this means, it’s good to have a mental picture of what an amp is. There are a lot of RVs on the road that are wired for a 30 amp electrical service.

Let’s see!ĭisclosure: Please note this post may contain affiliate links. And that’s when you need to run a 30 amp RV from a 50 amp campground pedestal. This is a very common scenario in many campgrounds.īut a less common scenario is just the opposite. In a previous blog post I discussed the possibility of needing to adapt a 30 amp campground service to a 50 amp RV. This article is about using a 50 amp to 30 amp adapter when you have a 30 amp RV.
