Isolation Transformer trips when connecting shore power sometimes

Occasionally when I plug in shore power, the Isolation Transformer trips out. I then have to lift the boards up and reset it, and all is fine. Any ideas why?

I have a multiplus inverter and a steel hulled boat. All the wiring is fine. I believe that later versions of the Isolation transformer don't have a trip at all.

The tripping maybe caused by inrush current into the transformers windings,when you first turn the shore power on, maybe lookup how to reduce inrush current on a large transformer
