A 30 amp plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements. A 50 amp plug has four prongs – two 120 volt hot wires, a neutral wire and a ground wire – that supply two separate 50 amp, 120 volt feeds.
Can I plug my 30 amp RV into a 50 amp plug without damage?
The short answer is yes, but it's not as simple as just plugging in your RV and hoping for the best. You really need to understand what you are doing and take appropriate safety measures to mitigate the risk of damage to your electrical system.Nov 16, 2020
