Because your issue is with the lights my first guess was a bad/shorted switch. However, if it's ALL your lights, I'm assuming they are controlled by other switches. Please verify that. The next guess is going to be a bad/loose wire in the breaker panel. I would NOT turn on the AC until you find the problem. AC units don't like low voltage when they first come on. No sense in adding to your problem. Start by checking your light switch for a bad wire/switch. Is it warm after you've had the lights on for a bit? Ditto for the breaker. Are all your lights on the same breaker in the box? Finally, even though you've been hooked up to the pedestal for months, are you sure you're getting 120V from the pedestal. Verify that also....let us know how savvy you are electricly. We don't want anyone getting fried trying to 'fix' a short....Dennis
