If you own an RV, one of the critical essentials you need to know is the correct power cord to power up your vehicle. Two primary RV power cords can be used: the 30-amp (30A) and the 50-amp (50A). While they may appear to serve the same function, specific differences differentiate them. Today, we shall delve into understanding these differences and how to choose the suitable power cord for your RV.
30A RV Power Cord
The 30A power cord is designed to supply power to a lesser extent due to its less powerful output. Its end plug usually has three prongs – a 120v hot wire, a neutral wire and a ground wire. Despite its limit in power supply, it is sufficient for smaller size RVs, with fewer power-heavy appliances.
50A RV Power Cord
On the other hand, a 50A power cord has four prongs – two 120v hot wires, a neutral wire and a ground wire. A 50A cord can deliver more power – almost double the amount of the 30A cord - making it more suitable for larger RVs with more appliances, multiple AC units, and other power-hungry systems.
Choosing the right power cord for your RV
Choosing between a 30A and a 50A power cord depends on your RV's power requirements. For smaller RVs with fewer power requirements, a 30A cord will suffice. However, for larger RVs with more appliances, a 50A will be better. Always keep in mind, using a 30A cord for a 50A RV can run the risk of overheating the cord, leading to potential fire hazards and causing significant damage.
Understanding the power requirements of your RV and the differences between the 30A and 50A cord is crucial to the smooth running of your RV. The right power cord not only reduces risk, but also enhances the efficiency of your RV.
