Jw, I would bet the UL testers do not test things in a "real world" enviroment.

The manufacturer will provide an installation technique or procedure upon which the UL tests the device, and it probably passes.

I can't imagine a UL tester installing them at a production rate, and on thier knees all day long for years.

The ole saying " it looks good on paper" comes to mind here.....


Dnk.....
