Thor Forums

[Beau388]

Also realize that each Thor Industries plant is it own entity. It seems no two plants use the same electrical components in their elecrical systems and their coach use philosophies are different. Electrical systems change year by year as more electronics are added and more versatile control systems become available.

For example there are simple inverters, combination inverter chargers, inverters with internal transfer relay, and hybrid inverters. All are wired different and have different control panels or no control panels at all. The electrical systems in a 2016 23 ft Freedom Elite is vastly different from 2023 ft Entegra Cornerstone, but both are Thor Industries motorized RVs.



I had the opportunity to tour the Thor MC plant 750 in 2016. It was late summer so the were producing 2017 floor plans. I asked specifically to see the wiring harness shop on the factory's second floor. The assembly room is about 200 feet long and 50 ft wide. The walls are lined with wiring boards and test equipment. In the center were bins of connectors lugs, ties, raps and flex conduit. At that time there were 6 floor plans of the Hurricanes/Windsports, 5 floor plans of the ACEs and 6 floor plans of the of the Freedom Travelers. Each floor plans requires two individual wiring harnesses (12volt and 120/240 volt). The 29 and 31 foot models of the Hurricane/Windsport could be 30 amp or 50 amp, so two different 120/240 volt wiring harnesses for those models. The factory was completing 6 to 12 coaches per day.
