So far, it seems that there is a group of breakers which is classified as being acceptable for use in other manufacturers' panels. I still don't see how that equates to being able to use an appropriately listed and classifed Murray or C-H breaker in, for example, a GE panel.
GE's label on the panel door and instructions for a standard residential grade panel say "use only GE breakers" or something similar.
From the 1999 NEC, section 110-3(b) "Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling."
The GE "instructions ... in the ... labeling" clearly state "use only GE ...".
Why is it not a code violation to use anything other than a GE breaker in a so-labeled GE panel? Taking that argument a step further, is it not true that all any manufacturer has to do is label their panel with "use only our breakers/components" and use of any alternate brand breaker/component becomes a code violation?
This has nothing to do with whether the breakers themselves are listed and/or classified for use in another manufacturers' panel. It's coming at it from the other direction where a manufacturer restricts use of any installed components to their own brand and puts that in a label on the panel.
Am I really misintepreting something here?
