I would be hard pressed to say that my 35 years of experience is superior to a NRTL such as UL.
UL tests the stab-loc of these devices and list them as an installation method. For me to say that the stab-loc is inferior would the same as saying that I am superior to the testing lab, a step that I am not ready to make.
Most of the people that I have a chance to talk to in person that make the statement that the stab-loc is inferior could not be convinced to make the installation. When ask for a reason or substantiation the only reason I get is, I just don’t like it.
I have yet to talk to someone who can give proof that even one stab-loc failed due to the device. Either the circuit was overloaded or a poor installation was made is the only reason I have heard.
