Notes 1) NEC = National Electrical Code
2) NEMA = National Electrical Manufacturers Association
3) The IP rating provided as an approximate comparison. A more accurate comparison is not possible, since different
ingress protection tests and assessment criteria apply.
The NEMA types cover the corresponding IP ratings but not the other way round. In general, NEMA/UL enclosure
protection testing is subject to stricter criteria.
4) For enclosures with knockouts.
