20 Amp House circuit will not power camper, generator will

Thank you for the quick replies, to answer the first question, yes the generator still powers everything I am trying to power, i ran the a/c, lights, radio and fridge for about 45 minutes without a problem. To answer the second question, in my other troubleshooting I had only the converter hooked up, no other 12V circuits attached to the converter so I don't think the fridge could be part of the problem. Thanks again for the replies,
Matt
