First of all, your Allegro has a 50-Amp service input. SO, if you're plugged into a 30-Amp campsite power box then you are using a 50-to-30-Amp adapter. Hopefully, you are using a standard adapter and not something homemade for this.
With this said, your current indicates that your RV has something else running because your Air Conditioner unit only pulls 5-8 Amps when running and maybe up to 12-AMPS when it is starting up. SO, I recommend that you turn OFF whatever else you have running (on 110-VAC) that is drawing so much current. Remember, 30-Amps means 30-Amps, and that's all you have available at the campsite, MAXIMUM!
It is common for people with a rig that runs on 50-AMP Service having to ration their use of power when they have to use a 30-Amp service, but regardless, your meter on your Surge Protector should not be indicating such high current readings normally.
