Answer 1

IEEE C57.12.28 is the industry standard for enclosure integrity of metal enclosed equipment such as compartmental transformers and switchgear.

The doors and windows must pass pry-bar and wire-probe tests to ensure that someone can not open up a gap and then stuff a 14 AWG soft-drawn wire into the enclosure.
