I have an on going debate with UL concerning HDD in hazardous locations. 
Their main concern is the motors used in the HDD and the fact that they must
be brushless, I am not debating that fact, but I have been trying to prove to
them that the motors used in the new HDDs are brushless and there is no need
to keep testing everytime we want to use a different HDD.  

Has anyone had a similar experience with UL? 

Thanks,
