Hi folks,

Well, more on the interesting topic of fire enclosures,

CSA/UL 60950-1 has

4.7.2.2 Parts not requiring a fire enclosure
The following do not require a FIRE ENCLOSURE:
- motors;
- transformers;
- electromechanical components complying with 5.3.5

The question is since motors and transformers can be a sources of fire hazards, 
anyone know what the logic is behind this exception?

Thanks
-Dave
