Change Summary

• Every recreational vehicle site equipped with a 50-ampere receptacle is now required to be equipped with a 30-ampere, 125-volt receptacle
• This ensures one 30-ampere, 125-volt receptacles to at least 20 percent of the RV sites within an RV park
• The electrical loads for modern recreational vehicles often demand a 30-ampere, 125-volt receptacle outlet

Expert Analysis

In the past, every recreational vehicle (RV) site with an electrical supply was supplied with at least one 125-volt, 20-ampere receptacle outlet, and a minimum of 20 percent of the RV sites were required to be equipped with a 50-ampere, 125/250-volt receptacle outlet.  Many modern RVs are manufactured with 30-ampere, 125-volt requirements. To facilitate these 30-ampere connections many campers were being sold “cheater” cords that adapt their 30-ampere, 125-volt RV supply cord to the 50-ampere, 125/250-volt recreational vehicle site receptacles. Since these “cheater” cords are never an acceptable solution, action by Code Making Panel-19 results in a requirement for an additional 30-ampere 125-volt receptacle at the same RV sites where 50-ampere 125/250-volt receptacles are required. This new addition of one 30-ampere, 125-volt receptacle to at least 20 percent of the RV sites within an RV park, where previously only a 50-ampere, 125/250-volt receptacle was in place, will be an equitable solution for the camper as well as campground owner. Although this action eliminates the need for “cheater” cords in newly wired recreational vehicle parks of the future, it does not generally impact existing parks. Generally NEC changes impact only new or upgraded RV parks or RV sites, but electrical professionals are encouraged to advocate for these safety upgrades.
