IP44 vs IP54
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP44 and IP54 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 5). IP44 is rated for > 1 mm — small wires and splashing water (all directions), while IP54 provides dust-protected and splashing water (all directions).
IP44 protects against small solid objects (1 mm) and splashing water from any direction. It is the common minimum rating for outdoor-covered fixtures and bathroom zone equipment.
IP54 is dust-protected (limited ingress, no harmful deposit) and resists splashing water from any direction. A versatile rating for industrial and outdoor-covered equipment in dusty, damp environments.

No direct NEMA equivalent.
Recommendation
IP54 offers higher overall protection than IP44. Choose IP54 for harsher environments; IP44 may suffice for milder conditions and can be more cost-effective.
