Protection against electric shock
8.2
60335-1(ed.3)


Question:
Is basic insulation accessible through opening in earthed metal enclosure having paint
coating acceptable?
Rationale:
See question.
Decision:
If the opening is such that the basic insulation is accessible without making contact at the
same time with the earthed metal parts, it is considered as a class II construction and thus not
acceptable.
If the basic insulation and the earthed metal parts are accessible at the same time, this is
acceptable, as the earthing is one if the protection means.
