Electrical boxes being buried in insulation aren't specifically discussed in the NEC, so I turned to my second book, Electrical Inspections of Existing Dwellings, courtesy of the same folks at Code ...

Electrical insulation is the cornerstone of high voltage system reliability, serving to impede undesirable current flow and thereby prevent catastrophic failures. Integral to the performance of ...

Electrical treeing represents a critical degradation mechanism in high voltage insulation systems, often leading to premature failure of polymeric materials. This phenomenon involves the progressive ...
