Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Underrated circuit breaker, 15 amp vice 20 amp, rating for rear air conditioner. Forward air conditioner, same model and size, has correct 20 amp circuit breaker. Overrated fuse d8, 20 amp vice 15 amp, on ceiling lights. This was found while stationary troubleshooting a water leak. I decided to see what spare fuses I may need and I noted these discrepancies.”
