Biggest issue is plugging the device into a 50amp out outlet with a 30 trailer, as the shore cable and wiring from the trailers inlet to the trailer electrical panel is not protected correctly. We routinely plug in our 50amp TT with and 30 to 50 amp adapter. Just a few minutes ago DW started the microwave while the WH and portable heater were running and we are on a 30AMP outlet. The hardwired PI unit dumped the power based on low voltage.

I see no problem running an adapter on each side of the portable PI unit. The PI unit will still do it's job of looking for open grounds or neutrals, reverse polarity , low or over voltage, freguency etc.

PI units do not error or trip on amperage, that is left to the circuit breakers.
