well one fella said never in 20 years,others were baffled why the 89 dollar multi plug surge protector did not work. 4 refrigerators, 2 inverters, 1 convertor, bose audio system, and everything in between; toasted at approx 6 am in the morning.
For some reason only one short side of the park was affected. Those without damage; one with a progressive surge guard and one with a 30 amp ecowise voltage regulator. The eco wise survived and resumed activity.
Fortunately all the stuff is being repaired with a good success rate. Oddly enough, most in the park do not have protection. The Parks in Mexico should post at the entrance to have a better compliance rate for electrical protection. Warning; Park not responsible for high and low voltage rates which may destroy the electrical system in your RV.
