Field Evaluation Service

Field Evaluation Service

General Information:

The Field Evaluation service that G&M provides is a “one-of-a-kind” inspection typically for electrical equipment or machinery that has been installed in the field, but does not bear the mark of a Nationally Recognized Test Lab (NRTL), e.g. UL, CSA, TUV, etc.  This service can be mandated by the city electrical inspector, utility, or by customer request.

Field evaluations are based on nationally recognized standards and are intended to confirm that equipment in the workplace meets a minimum level of safety.  This is a requirement that electrical inspectors will often enforce, but also shows due diligence on the end user’s part in providing a safe work environment.

G&M follows the procedures for competency of Field Evaluation Bodies (FEBs) outlined in NFPA 790.  In addition, we follow the recommended practices for equipment evaluation specified in NFPA 791.  Most importantly to our customers and local jurisdictions alike, G&M is:

  • A team of seasoned field veterans, with
  • Experience to understand the intent of the specifications, enabling us to
  • Practically apply the concepts across a wide variety of equipment and differing conditions

G&M field engineers have the experience and expertise to competently assess equipment in the field, and to quickly ascertain if it meets the intent of applicable safety standards given workplace environment and operating conditions.

G&M specializes in the following areas:

  • Switchgear Modification – Modifications made to an existing panel or switchgear in need of field inspection to UL 891. In particular bus taps made on the line or load side for connection to solar power, or line-side taps for the addition of a new section are often times required to be re-certified in the field.
  • Schematic Generation – Field generation of power schematic diagrams for control panels. It is impossible to assess basic safety requirements without an overall understanding of the components that make up each power circuit in the system.  Without a power schematic it is very difficult to assess how many circuits there are, and which components are associated with which circuits.  G&M can assist in generating this important documentation for panels that have missing diagrams or equipment that has been modified from its original design.  The schematic generated will accompany the equipment thought it’s life, and may prove to be invaluable for troubleshooting and maintenance in the future.
  • Products from Asia – Industrial products built in Asia, and particularly China, generally are not designed to meet U.S. safety requirements. If these types of products are to be subjected to U.S. regulations, it is best to have a compliant product from the factory, prior to shipment, in order to avoid retrofitting and customization on site.  G&M has an office in Beijing China, which communicates directly with factories in Asia.  Our local experts in the U.S. work with our Beijing team to communicate mandatory U.S. requirements, and bring products into compliance before they ship.
