We have the Progressive Industries EMS-PT50X RV surge protector. We purchased an external surge protector even though our RV has one onboard. We want to make sure the pedestal is safe before we plugin. There have been a couple of occasions in which it found a bad pedestal. Thank goodness we didn’t plugin. Who knows what could have happened.
RV Electrical PSA: ALWAYS, ALWAYS, ALWAYS turn off the breaker before plugging or unplugging your RV. It prevents arcing and pitting of your plug.
