NEMA ↔ IP Rating Cross-Reference Tool
Convert between NEMA enclosure types and IEC 60529 IP codes. Pick a NEMA type to see its approximate IP equivalent, or enter an IP code to see the NEMA types that match. The mapping is approximate — NEMA also covers corrosion, ice and construction that IP does not.

NEMA to IP, at a glance
| NEMA | Approx IP | Notes |
|---|---|---|
| NEMA 1 | IP10 | Indoor, limited access. No drip or dust protection. |
| NEMA 2 | IP11 | Indoor, drip protection from above. |
| NEMA 3 | IP54 | Outdoor, rain and dust limited. No ice formation. |
| NEMA 3R | IP14 | Outdoor, rain and sleet; no dust rating. |
| NEMA 3S | IP54 | Outdoor, rain and sleet; external ice unaffected. |
| NEMA 4 | IP55 | Indoor/outdoor, splash and dust. Often cited as IP56. |
| NEMA 4X | IP66 | Outdoor, hose-down, corrosion resistant. Approx IP66. |
| NEMA 5 | IP52 | Indoor, dust limited, dripping water. |
| NEMA 6 | IP67 | Temporary immersion, outdoor. |
| NEMA 6P | IP67 | Prolonged immersion, outdoor; often IP68. |
| NEMA 12 | IP52 | Indoor, dust and dripping/oiling. Often IP54. |
| NEMA 12K | IP54 | Indoor, dust and dripping/oiling with hose test. |
| NEMA 13 | IP54 | Indoor, dust, spray and oil. |
NEMA and IP measure different things
NEMA (NEMA 250) covers ingress plus corrosion, ice formation and construction; IP (IEC 60529) covers solids and water only. A NEMA 4X enclosure is roughly IP66 but also corrosion-rated, which IP does not express. Always confirm the supplier's tested rating for your site.
- IP = solids + water (IEC 60529)
- NEMA = ingress + corrosion + ice (NEMA 250)
- Use both when exporting
From code to drawing
Once you have the rating, use the IP rating selector to confirm it from the site, and read how NEMA and IP map for enclosures and the IP rating guide for outdoor enclosures.

A NEMA 4X enclosure is approximately IP66: dust-tight and protected against powerful water jets, and it is also corrosion resistant. IP does not express the corrosion rating, so confirm the supplier's tested rating for a coastal or washdown site.
No. NEMA 250 covers ingress plus corrosion, ice and construction; IEC 60529 IP covers solids and water only. The mapping here is approximate for selection, not a substitution for the supplier's tested rating.
Outdoor under cover commonly starts at IP65; exposed or hosed sites use IP66. Use the IP rating selector to confirm from the actual site, then specify the gasket and door seal that deliver it.
Approximately. IP67 (temporary immersion) maps to about NEMA 6, and IP68 to NEMA 6P. Again, NEMA also covers ice and corrosion that IP does not, so match the full environment, not just the digits.
