Power Protection..Why So Few Have If Really Needed?

You can buy a 50 amp Progressive EMS for $431. A new air conditioner will cost you $1000 or more. We were just at Wilson's Riverfront Campground a few weeks and ours shut off the power like it should so I just hooked up my autoformer and we were OK for the week. I would never stay at that park again as there starting voltage was 108 before you turned anything on. They are worth the money if you go to multiple places like we do being fulltime.
