The table below provides an equivalent conversion from NEMA Enclosure Type Numbers to IEC
Enclosure Classification Designations. The NEMA Types meet or exceed the test requirements for the
associated IEC Classifications; for this reason this table cannot be used to convert from IEC
Classifications to NEMA Types.
The comparison is based on tests specified in IEC Publication 60529, and is from NEMA Publication 250.
