Under What Circumstances Is It Prohibited to Install Explosion-Proof Equipment

1. Verify that the data on the electrical equipment’s nameplate aligns with the connection voltage and capacity of the machinery.

2. Ensure the equipment’s external structure is intact, and its explosion-proof performance is up to standard.

3. Check for any internal damage to the equipment.

4. Confirm that all inspection records and acceptance procedures are complete and available.

Explosion-proof equipment should be considered non-compliant if it exhibits any of the following issues: newly received explosion-proof equipment lacking explosion-proof markings, production license number, explosion-proof certification, inspection certification, or a delivery acceptance form for explosion-proof equipment. Additionally, if the equipment has lost its explosion-proof capabilities and cannot be restored to meet explosion-proof standards even after repair, it should be regarded as non-explosion-proof.
