boje,
as you maybe aware Lippert Components, a company of Drew Inc, has it's own website -
www.lci1.com with alot of Support info and numbered LIP Sheets concerning their components.
LIP Sheet 0058 may help with your inquiry. It shows
original configuration then a
new configuration. The original is 50A and the new is 80A in LIP0058. I would suggest you contact Keystone/or Lippert directly for their input. It appears you have a new model and repairs or mods can be accomplished with no expense to you if there is a problem. I am not an electrician just a Montana owner. Hope this helps. Click below.
