Import Tips & Compliance

• Provide UL File E87415 or equivalent certification proving suitability solely for QO panelboards to justify principal use with heading 8537

• Document NEMA enclosure type (e.g

• 1, 3R) and breaker compatibility; mislabeling as cabinets can trigger reclassification

• Avoid shipping with breakers installed, as assembled units shift to complete panel classification under 8537.10
