What percentage of electrical supplied RV spaces in a recreational vehicle park must have 50-ampere receptacle outlets?

1. 10 percent

2. 15 percent

3. 20 percent

4. 25 percent

The correct answer is: 20 percent

In recreational vehicle parks, there is a requirement for the percentage of RV spaces that must be equipped with 50-ampere receptacle outlets to accommodate varying power needs of users. The National Electrical Code (NEC) specifies that at least 20 percent of the electrical supplied RV spaces should feature 50-ampere receptacle outlets. This standard ensures that enough spaces are available to support larger RVs that may require more power, enhancing the functionality and appeal of the park to a broader range of RV users. This provision recognizes that while many RVs operate efficiently on lower amperages, there’s a significant number that would benefit from higher capacity outlets to run additional appliances and systems without risking overloads or inconvenience. Hence, having 20 percent of the spaces with 50-ampere receptacles is a crucial aspect of planning and safety for recreational vehicle parks.
