If a UL recognized component power supply (UL1950) has been tested for abnormals and meets the requirements of clause 5.4.9, does it need to be mounted inside a fire enclosure or is it considered a "component not requiring a fire enclosure" as described in clause 4.4.5.2? In other words, can it be mounted in a plastic enclosure with holes in the bottom?
