IP56 vs IP02
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP56 and IP02 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 6 vs 2). IP56 is rated for dust-protected and powerful water jets (12.5 mm nozzle), while IP02 provides no protection and dripping water at 15° tilt.
IP56 is dust-protected and resists powerful water jets (12.5 mm nozzle, 100 kPa). Suited to outdoor equipment subjected to heavy rain or hose-directed water.
Engineered to deliver no protection against solid objects and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. Classified as IEC 60529 ingress protection code IP02, it pairs solid level 0 with liquid level 2.

The exact difference (IP56 vs IP02)
Solid protection
IP56
Level 5 — Dust-Protected
IP02
Level 0 — No Protection
IP56 provides "Dust-Protected" (level 5), while IP02 provides "No Protection" (level 0). IP56 is 5 levels higher.
Liquid protection
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP02
Level 2 — Dripping Water at 15° Tilt
IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP02 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP56 provides 4 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IP02. Choose IP56 for harsher environments; IP02 may suffice for milder conditions and can be more cost-effective.
