Visited Tyler State Park last week to checkout our new 2020 Caravel
trailer. Plugged my 30 amp progressive electrical management protecter (9 yrs ago purchase for another trailer). 2 minutes go by, it clicks on, everything ok. Plug in the trailer. Hope sets the time on the microwave. Then we take a short walk and get back and the microwaves gone to zero. Check the surge protector and it throwing out a 03 reading, not being an electrician, chart says Hi voltage. Call park and they ask me to unplug my trailer and they send 2 guys out to check it out. They replace the 50amp & 30amp plug and breaker. He shows me the 30 amp plug and one of the poles is charred and melted. He say in the spring they'll average replacing 15 to 20 plugs a month. Everything worked fine for the rest of our stay. I bought the surge protector because a client of mine had bought a new Holiday Rambler motor home and immediate took it to Southern Colorado to stay for the summer. While there lightening hit the park and fried is motor home. Coarse it was covered by a warranty. Tried getting insurance to total it. Nope. Towed it to New Mexico, seems like back then Grey Hound had a plant there. Over 3 months replaced the electrical systems. Often wondered if my $250 progressive system would have prevented that situation. I'm not an electrical guy, so I don't know?
