Import Tips

• Verify voltage rating exceeds 1,000 V and document integrated 8535/8536 apparatus to confirm 8537.20 classification

• Obtain manufacturer's test certificates for arc resistance and short-circuit withstand to meet NEC/UL standards

• Avoid misclassification as low-voltage panels (8537.10); check for proper IP rating documentation
