Chain Surge Protectors / UPS in series

[mookie1590]

I'd probably say not to, there are some parts that let voltage flow when it reaches so many volts, then opens up like a blood gate. If two of these are together it could cause issues. Just like a simple resistor, 2 in series adds the ohms where as if it's parallel they will divided each other so 10 ohms and 10 ohms in parallel is 5 but in series is 20 ohms. If I had a bunch I'd crack them open and run some experiments, put my oscilloscope on it and test this idea, even then I could just google some schematics but honestly I'm in lazy pos mode Right now.

 

Maybe some users here would be so kind to run these tests themselves. my lab is 10 feet awwawy and I don't really feel like it spongebob.jpeggy
