F.A.Q

01

What information is required for custom NEMA enclosure design and acceptance?

Provide: installation location, temperature range, dust type, water source/pressure, oil/coolant details, corrosive media, submersion depth/duration, dimensions, internal equipment, cutouts, cable entry, and material/finish requirements.

02

Does a NEMA enclosure mean explosion-proof, corrosion-resistant, or completely waterproof?

No. NEMA ratings define protection against specific environmental factors, but do not automatically grant explosion-proof ratings, universal chemical compatibility, absolute waterproofing, continuous submersion, or high-pressure washdown capability.

03

How to choose between NEMA 4 and NEMA 6?

NEMA 4 resists rain, windblown dust, splashing, and hose-directed water; NEMA 6 adds protection against temporary limited-depth submersion. The key difference is whether water might submerge the enclosure base or door frame.

04

What is the difference between NEMA 4 and NEMA 4X?

NEMA 4 protects against windblown dust, rain, snow, splashing, and hose-directed water. NEMA 4X adds corrosion resistance, ideal for coastal, chemical, wastewater, food processing, and washdown environments.

05

How to distinguish between NEMA 3, NEMA 3R, and NEMA 4?

Both NEMA 3 and 3R handle outdoor rain, sleet, snow, and icing. NEMA 3 also protects against windblown dust, whereas NEMA 3R does not prioritize windblown dust protection.

06

What are the differences between NEMA 1, NEMA 5, and NEMA 13?

NEMA 1 is for general indoor use (personnel and falling dirt protection). NEMA 5 adds protection against settling dust, dirt, and dripping non-corrosive liquids. NEMA 13 is designed for machine-tool environments exposed to oil, coolant, mist, and splashing.

07

Can NEMA types and IP ratings be directly converted?

No direct 1:1 conversion exists. NEMA covers ingress of solids and water, plus windblown dust, oil, coolant, external icing, corrosion, and temporary submersion. IP ratings primarily classify ingress of solids and water.

08

How to choose the right NEMA enclosure based on site conditions?

First verify 5 factors: mounting location, primary contaminants, water sources, corrosive media, and potential submersion risk.
