IP20 finger-safe ratings can be conditional, requiring proper preparation to achieve the rating.

• A. True
• B. False
• C. Not related to finger-safe rating
• D. Only applies to enclosures

Answer: (B)

IP ratings are fixed protections defined by a standard and confirmed by tests. IP20 means the enclosure protects against solid objects larger than 12.5 mm and has no special protection against liquids. The idea of a “conditional” finger-safe rating implies you must prepare something to achieve the rating, but the rating isn’t something you earn by a setup step—you rely on the product’s design and testing to meet the specification. If the enclosure is designed and tested to IP20, it has that rating; if you modify it in a way that compromises the seal or openings, you could lose the rating, but that’s about maintaining the rating, not about a conditional qualification to obtain it. So the statement isn’t correct.
