During each field evaluation, we will contact the local inspector and communicate our intended process to ensure the AHJ will be completely satisfied.

We are continually involved with local Authorities Having Jurisdiction (AHJ); attending their meetings and forums to gain a complete understanding of what inspectors need and want.

According to OSHA workplace safety requirements called out in 29 CFR Section 1910.303 and the National Electric Code (NEC) – NFPA 70:2023– Article 110.2 … all “conductors and equipment” must be “approved,” “identified,” “listed” or “labeled”. In accordance with these requirements, if your local electrical inspector or building official finds installed equipment that does not comply with electrical product safety standards, that product will not be approved for use until all applicable product safety requirements have been met.

  1. Authority Having Jurisdiction (AHJ) ‘Red Tags’ equipment (pre-permit or post-permit)
  2. Manufacturer contacts the AHJ approved test lab (1-800-967-5352)
  3. Applicable requirements/specifications are determined
  4. Quote issued to the client
  5. Manufacturer accepts and signs quote
  6. Evaluation date is scheduled and conducted
  7. If product is found to be in compliance with applicable requirements/specifications the unit is labeled and a Letter of Compliance is issued which states the following:
    • Inspection site/equipment inspected
    • Standard(s) utilized in evaluation
    • Performance tests conducted
    • Label number(s) applied
    • Controlled Report No.
  8. If product is found to be non-compliant with applicable requirements/specifications a non-compliance report is issued which states the following:
    • Inspection site/equipment inspected
    • Standard(s) utilized in evaluation
    • Performance tests conducted
    • Construction and performance failures

During the field labeling process our engineers will evaluate your product for the following:
