Inspection of the wire spools was always the sticking point with the inspector as well. He's always find one spool without a label. When I first questioned the label vs. the indications on the wire insulation itself, I was given this explanation:
The wire insulation typically only has the letters 'UL' and/or 'CSA' No logos. UL and CSA have rights over the use of their logos, but anyone can put 'letter' on the insulation Additionally, the use of the 'letters' on the insulation does not necessarily mean that the wire was indeed evaluated by UL or CSA. It can simply mean that the product is 'designed to meet the flammability requirments'. Further, the labels on the spool are applied by recognized 'respoolers'. If the spooling process is not carefully monitored, the insulation can be 'stretched' making it thin in some areas, perhaps compromising the rating.

This one is just a curiosity and maybe someone in this group knows the answer. Four times a year we are audited for our NRTL certifications and the inspector makes it clear that using wire in our products with the UL recognition and CSA certification marks is not sufficient. Even though we have incoming inspection records, it seems they always want to see the wire spool in our stock rooms and make sure it has the proper labels. I understand all the concerns with using an approved respooling house to maintain the integrity of the wire. What I don't understand is how a simple adhesive label on the spool is better evidence than the embossed markings that appear along the entire length of the wire. It seems to me that if someone wished to fraudulently mark a wire as approved material, the labeling of the spool is easily done and would be the least of their worries. Can anyone explain the history behind this requirement? thanks, -doug ----------- Douglas E. Powell, Compliance Engineer Advanced Energy Industries, Inc. Mail stop: 203024 1626 Sharp Point Drive Ft.
