F.A.Q

01

What data is needed for custom NEMA enclosure design and acceptance?

Provide mounting location, temperature range, dust type, water source/pressure, oil/coolant details, corrosive media, submersion depth/duration, dimensions, internal gear, door cutouts, entry directions, and material/finish requirements.

02

Are NEMA enclosures explosion-proof, corrosion-proof, or fully waterproof?

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

03

How to choose between NEMA 4 and NEMA 6?

NEMA 4 handles rain, windblown dust, splashing, and hose-directed water. NEMA 6 adds protection against temporary submersion at limited depths. The choice depends on whether water levels may rise above the base or door opening.

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, humid, chemical, wastewater, food processing, and washdown environments.

05

How do NEMA 3, NEMA 3R, and NEMA 4 differ?

NEMA 3 and 3R are for outdoor rain, sleet, snow, and external icing. NEMA 3 also protects against windblown dust, whereas NEMA 3R focuses on rain, snow, and ice without windblown dust protection.

06

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

NEMA 1 is for general indoor use, providing personnel protection and basic falling-dirt protection. NEMA 5 adds protection against indoor dust, dirt, and non-corrosive dripping liquids. NEMA 13 suits machine-tool environments exposed to oil, coolant, mist, and spraying.

07

Can NEMA types and IP ratings be directly converted?

No direct 1:1 conversion exists. NEMA types cover solid objects, water ingress, windblown dust, oils, coolants, icing, corrosion resistance, and limited submersion. IP ratings focus mainly on ingress of solids and water.

08

How to choose the right NEMA enclosure for your site?

Confirm five factors first: location, primary contaminants, water sources, presence of corrosive media, and potential submersion risk.
