OK, yes I understand.
In my 30A days, I would measure the voltage at the pedestal plug to see how close it was to 120V. Never thought about looking for double the voltage altho I had a strange occurrence...
Meter read 175V, What?, wait. Turned out the battery in the meter was the culprit. That'll make you think when you don't want to at 10PM and trying to setup.
Back to the question, be suspicious of all your electric components for awhile...Voltage issues can take time to appear. Listen for little hums or turn on an AM radio, listen for static as you turn on/off things. Could be the component is naturally noisy, but I would list it as possibly affected. After my home got hit by lightning, I was amazed at the subtle damage.
