-Before plugging into shore power the RVer may want to test the receptacle for "good ground, open circuits, reversed polarity and safe voltage."((http://50amppowerpal.com/pages/faq)) 
-Note that the tester reports conditions at the time of testing;  it might tell you if voltage is too high right now but not protect the RV if the voltage spikes later on.

 +A power tester can check for the presence of power, "good ground, open circuits, reversed polarity and safe voltage."((http://50amppowerpal.com/pages/faq))

 +The one shown here is for 120vac outlets but others are available [[https://amzn.to/3zeRJTx|for 30A outlets]] and [[https://amzn.to/4e03XPe|for 50A outlets]].

 More [[http://amzn.to/2iwu7Ra|full-featured surge protectors]] will disconnect power to the RV in over/undervolt conditions and will reconnect after a certain period of stability.   More [[http://amzn.to/2iwu7Ra|full-featured surge protectors]] will disconnect power to the RV in over/undervolt conditions and will reconnect after a certain period of stability.  
  
 +==== transfer switches ====
 +
 +A //transfer switch// allows you to run AC loads off the inverter, but switch to shore or generator power instead when that source is available.  
 +
 +  * inverter output -> transfer switch AC source 1 (default)
 +  * shore power -> transfer switch AC source 2 (use grid power when you have it)
 +
 +and 
 +
 +  * transfer switch output -> AC loads
 +
 +
 +Since RVs spend more time on pedestal power than campervans such devices are more common on RVs.  
 +
 +The switches can be manual or automatic.  On the latter, the switchover time is measured in milliseconds.
