Terry, If you step back in the list it specifically allows "openings in the bottom of any size under: PVC, TFE, PTFE, FEP and neoprene insulated conductors and their connectors"

Hello: I have a question about the interpretation of UL 1950 / En 60950 sec 4.4.6 Fire enclosure construction. "The following constructions are considered to satisfy the requirement without test: .... openings in the bottom, each not larger than 40 mm sq under: @ components of FLAMMABILITY CLASS V-1 or better, or FLAMMABILITY CLASS HF -1 or better, or @ parts made of material of FLAMMABILITY CLASS V-1 or better, or FLAMMABILITY CLASS HF -1 or better;" Is there any correlation between VW-1 wire and UL 94 V-1 FLAMMABILITY CLASS ? That is to say if all parts are V-0 or V-1 and wires of VW-1 would this construction be considered to comply? What is the best way to get information on the various wire classes UL 1581, 1180, 3239 etc. Your input is appreciated! Terry J.
