SaferProducts.gov consumer incident report 20141111-85772-2147438989. Severity: Incident, No Injury. Product: Generac Guardian 0052420 (Generac Guardian whole-house standby generator, model #0052420).

Meantime, I have discovered several appliances in addition to the A/V receiver that are no longer operable. He also told me that had I not been home and/or had not shut down the generator, a fire would likely have broken out. I have spoken to several people who sa
