Every camping season brings the same wave of emails: shore power connectors overheating, right around the same stretch of extreme summer heat. It’s not a coincidence. Running air conditioners and other high-draw appliances pushes an RV’s electrical system harder than almost anything else it does all year \u2014 and if a connector in that circuit isn’t in top shape, that’s exactly where the strain shows up first.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

Reports of shore power plug meltdown tend to spike during extreme heat spells \u2014 precisely when air conditioners and other appliances are drawing the most current, and precisely when a marginal connector has nowhere to hide.<\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Why the 30-amp pedestal outlet takes the brunt of it<\/h2>\t\t\t\t<\/div>\n\t\t\t\t

Of all the connections in a shore power circuit, the pedestal-side plug tends to show the most wear. It looks rugged, but a 30-amp connector is only rated to carry 50% more current than a standard household 20-amp outlet \u2014 not the wide margin its size might suggest. Add in a busy camping season’s worth of plugging, unplugging, and weather exposure, and it’s easy to see why this is where problems tend to start.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
