 Boondockers and vandwellers will likely set up their shore power to run on the 15A.  Because of the backward-compatible 20A socket they will be able to use their 15A plugs at both 15A and 20A hookups.  Boondockers and vandwellers will likely set up their shore power to run on the 15A.  Because of the backward-compatible 20A socket they will be able to use their 15A plugs at both 15A and 20A hookups.

 **IMPORTANT:**  This same connector is used residentially for electric stoves, which use 240v.  If you are having a shore power receptable installed ensure the installer knows your RV runs off 120v.   **IMPORTANT:**  This same connector is used residentially for electric stoves, which use 240v.  If you are having a shore power receptable installed ensure the installer knows your RV runs off 120v.
