The hazard
On certain fifth wheel and travel trailers equipped with a generator-ready option, if the fasteners on the power transfer switch are not tightened to proper specifications, the elevated electrical loads associated with RV use in higher ambient temperatures may cause overheating of the lugs and degrading of the electrical connections. This condition may result in further degradation of the electrical connections, elevated case temperatures and an increased risk of appliance and other property damage. Correction: Dealers will inspect the transfer switch for evidence of heat damage and verify the fastener torque. If the inspection reveals evidence of heat damage, the switch will be replaced.
