50 amp service not recognized

First time out in our 3200 connected to 50 amp shore power, the load management system wouldn't recognize we were connected to 50 amp service, just 30 amps. The power cable is fine as we connected to another trailer and 50 amp service was good. We disassembled the power receptacle entering the trailer and all connections were fine.

I believe there is a WFCO transfer switch (T57?) that is responsible for detection of the service type? Has anyone experienced an issue like this? I have an appointment scheduled for the dealer next week to address the issue.

The LMS senses service type. Pull the cover off your fuse box and you will see a relay block on the side wuth the white wire from your transfer switch going thru a hole (ammeter) in that relay block. That relay controls shedding of the main and garage AC.

Try pressing the button below the service type indicator lights. You can cycle to lower amperages in order to "manage" load shedding

This is the relay block inside your fuse box. It senses service type by way of being an ammeter (the hole).

The button below the service type indicators only cycled between "30" and "20" so it appears that 50 amp service wasn't sensed. Thanks for the tip on the current sensor. I was curious how the amps were sensed.
