We get this question a lot. You can still use that pedestal, but you’ll need to use a 30-to-50 adapter or “dog bone” to plug into the pedestal first. This also goes for anyone in a 30-amp RV that gets placed at a 50-amp pedestal, except they need a 50-to-30 adapter. To plug in with an adapter, plug the adapter into the pedestal first, then plug the Surge Guard unit into the adapter, and finally plug in your RV power cord. Again, do all of this before turning power on at the pedestal.
