xantrex freedom 458 inverter problems

Has anyone had the problem of the hot wire coming into the inverter getting hot and melting the wire nut connecting it to the inverter? I've had this happen twice and when it does of course you lose all of the outlets on the inverter circuit in the motorhome. Recently one of my friends had it happen to him with the same setup. Why doesn't it pop the 30amp breaker before it gets that hot? We both have a Samsung 18 cubic ft. residential refrigerator on that circuit, but of course not using the inverter when plugged into shore power. The strange thing is you can still operate that circuit on the inverter when it happens, but of course the batteries will not get charged.

  • 1. The Wire Nut is not the correct gauge for the amp connection
    2. The 2 wires are NOT tight in the wire nut and are slightly loose and that cause minor arcing and heat build up on high amp current draws. Which gets worse as the wires get hot and more loose until it melts the wire nut. Make sure you strip back the burnt wires until you get good clean shiny copper. Doug
  • 1. The wire is too small for the current draw.
    2. Wire nut; another problem area use crimped splices.
