IP30 vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP30 and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 0) and liquid protection (level 0 vs 8). IP30 is rated for > 2.5 mm — tool / wire and no protection, while IPX8 provides no protection and continuous immersion (manufacturer-specified).
IP30 protects against tools and 2.5 mm solid objects but offers no water protection. A basic indoor rating for equipment in dry, low-dust environments where only tool-access protection is required.
IPX8 protects against continuous immersion under manufacturer-specified conditions (depth and duration), with solid protection not specified. The standard for submersible consumer electronics.

The exact difference (IP30 vs IPX8)
Solid protection
IP30
Level 3 — > 2.5 mm — Tool / Wire
IPX8
Level 0 — No Protection
IP30 provides "> 2.5 mm — Tool / Wire" (level 3), while IPX8 provides "No Protection" (level 0). IP30 is 3 levels higher.
Liquid protection
IP30
Level 0 — No Protection
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP30 provides "No Protection" (level 0), while IPX8 provides "Continuous Immersion (manufacturer-specified)" (level 8). IPX8 is 8 levels higher.

Recommendation
IPX8 offers higher overall protection than IP30. Choose IPX8 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
