My $300 waterproof and ten feature state of the art surge protector to protect my entire electrical system for my cabover from A1 Auto - which saved me any potential disaster 3 times already....
One RV Park showing reverse polarity....
One RV Park showing low voltage....
At my stepbrother's place in northern California showing excessive high Hz....
I was like, hey bro - I had to reset my surge protector a few hours ago as for whatever reason your garage outlet showed a higher frequency output than it was suppose to flow since I am plugged in with my extension cord on your grid...
Stepbrother stated, oh you mean that immensely over rated expensive surge protector that you rave about as state of the art that any 6 other typical surge protectors can protect it anyway with that price...
Nope - my house doesn't have any electrical issues at all....Although my son's power supply unit on his computer did fry earlier this morning as he was troubleshooting it for diagnostics and -YOU MEAN TO TELL ME THAT SURGE DETECTOR OF YOUR'S ACTUALLY DETECTED THAT FROM ANOTHER CIRCUIT ?????
And my portable floorboard refrigerator-heater that's thermostat controlled from Scamazon - keeps the water and fruit nice and cold when on the road.
