We used our Cascade last in July. Just went to check on it. It's parked under my barn and hooked up to power. Everything is dead. No lights, power control panel, no power except micro wave when plugg...
It could be a bad breaker, but not likely. I would still verify the voltage at the breaker and then start tracing the wire. If you can't easily trace the wire along its entire path, it might be difficult to troubleshoot. Is there more than one outlet in the basement compartments? If so, are all of them dead?
