Looks perfectly normal to me. I often see a few volts different between legs on our hard wired HW50C and the amperage draw will reflect what's running on each leg.

With those numbers, why would you expect a error message ?

I don’t see reason for error but I do wonder why the 2 amp leg shows a lower voltage than the 22 amp leg, worth looking into.

Progressive doesn't care about amps, it monitors volts.

Its not going to fault out and show errors unless the volts go below something like 109 or above something like 123 volts.

Amps will be determined by what you turn on. Up to 50 amps on each leg. They don't have to match.

TwinBoat just posted an article on "50amp service". Well worth the read. Certainly explains all the readings you are getting - which are fine! Voltage can be different on Legs 1 and 2 coming into the coach and amps will almost always be different depending on what equipment you are using.

Sounds ok. What is the expectation or problem being experienced?

I'm guessing that you're wondering why one is 22 amps and the other is 2 amps. You're Progressive unit is there to monitor VOLTAGE. So the 117 and 115 are the volts coming into your coach on the two 50 amp circuits. Being a couple of volts different is no big deal.

The AMPS you're seeing is what YOUR coach is currently USING in power. Something(s) that you're using in the coach is drawing 22 amps on half of the circuit, like your air conditioning. The other circuit is using 2 amps. If you turn something else on in the coach.....the 2 amps can jump to 15, 18, 25, etc.
