ECN Forum Forums Code Related Discussion NEC & other Code issues Terminal barrier strips instead of wire nuts?

Does anyone know if the terminal blocks shown are UL Listed?? Or are they a Recognized Component. If the latter then they cannot be used off-hand in place of Listed connectors, only as a part of a Listed product after evaluation of the total product. Also, if Listed, are they required to be secured in-place and what is the tightening torque for the terminals?
