 ====== Shore power ====== ====== Shore power ======
-Shore power is AC power derived from the electric grid.  The most common places RVers use shore power is when plugged in at someone's house  or at an RV park with full hookups (FHU).+

 +Shore power ("grid power", "mains", "wall outlet power"is AC power derived from the electric grid.  Shore power can run AC loads directly in campers so equipped, but more commonly it powers a [[electrical:converter|converter/charger]] that runs the [[electrical:12v:intro|12v house system]].

-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. +Because of the backward-compatible 20A socket folks folks can plug in their 15A rigs at both 15A and 20A hookups.

 +Mike Sokol of RV electrical fame, says:

 +> if there’s a 20-amp circuit breaker and 12-gauge wire feeding a 15-amp outlet, it’s actually rated for 20-amps of current. There’s an exception in the code as well as UL allowing this, so don’t worry. If you’re on a 20-amp breaker with 12-gauge wiring, then you have a 20-amp circuit, even if it’s using a NEMA 5-15 outlet.((https://www.rvtravel.com/softstart946/))
