I too can see where this gets confusing. I would ask the EC to provide me paper work from the wire manufacture stating that the "goo" is not needed, and I would pass the job. Now if the connector people still want the goo, then the job might fail under 110.3(B)Again, I think the manufactures should get together and work their problems out, then notify, UL, IAEI, and contractors as to the correct way to install their products.
