If a product that is UL listed does not meet the local code, is it mandatory to bring that product up to the local code?
Example: a group of VAV boxes came out to a job that had a Chicago plenum ceiling. The code does not allow greenfield (Metallic Flexible Conduit) in plenum ceilings. It does however allow for Sealtite or Liquidtite in plenum ceilings.
The VAV box came UL listed from the factory with a piece of greenfield on it. Do we void the UL listing if we change the greenfield to sealtite to satisfy the local code?? Or does the UL listing supersede the AHJ?
We had a similar incident where a Chiller came out to the jobsite with greenfield on it and the inspector noted that greenfield was not acceptable for use in an area where it could get wet. (The chillers were on the roof of a building. The greenfield was below the chiller but still exposed to the elements.)
Same question, Do you void the UL listing if you change the greenfield to Sealtite??
