Refrigerator Power Fail alarm

[GregOConnor]

I plan on setting one of these units up on the inside of my Bus so I can stop opening the refer door to see if the light is working to indicate there is 120V to my residential refer. I also plan on installing one off one leg of the 50 amp shore power supply so I can hear if power is off when I pass the parked rig
