Our third stay in Texas this trip. When I plugged in the surge protector (without the power cord) I had an l1fault so I switched to our thirty amp surge, it showed a ground fault. We called it in and they gave us a new site and closed this one for repair .
As you can see I also made my own plug to surge security lock. Once I screwed it together I I used a chisel to damage the screw threads. Now I leave the brass lock always connected an the red lock comes off so I can test with the surge guard by it’s self.
