 +[[lifestyle:words_of_wisdom|Words of Wisdom]]: "...most people think that to have “RV” type shore power you need those special 30/50 amp plugs. I have a 115v plug. The male end of an extension cord (heavy gauge) that I have cable tied to the inside of my receiver hitch so it’s hidden." -- Captain_Dapper((https://www.reddit.com/r/vandwellers/comments/cnt2o0/my_stealth_window_unit_setup/ewhggpj/))

-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]].

 +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/))

 +A //shore power port// is designed to let you plug power cables into the side of your van or RV.  As discussed above, RVs typically use 30A/50A service -- they use [[https://amzn.to/2TCV4WJ|this kind of port]].
  
 +Vans typically use [[https://amzn.to/2VUwDAI|15A ports]].   [[https://amzn.to/2F8SChD|Some are pre-cabled]] so you can plug the inside cable to a [[https://amzn.to/2F7sZxI|power strip]], [[https://amzn.to/2VWXHPQ|breaker box]], or other distribution device.  A [[electrical:converter|converter/charger]] can then be wired to the distribution point.
  
 +  - use a [[https://amzn.to/2EZka7E|hole saw]] to bore the hole in the van wall to the port's specification
 +  - sand the edges to remove sharp edges
 +  - treat edges with paint, primer, rust preventive, etc to prevent rust.  The edges will not be visible once the port is installed
