Finished installing my 10 circuit transfer switch and outside connection box. Started my Wgen7500 and connected my 25 ft power cord. Went inside to my panel and switched all 10 switches to gen and ran my whole house except dryer and A/C. Both watt meters were balanced at 1540 watt and gen never really went under any load. Ran it this way for an hour before switching back to line power and cooled the generator. Wow, I was impressed with this unit. Thanks Westinghouse.
