Electrical Safety Evaluation of Thermocouple Circuit Design for Shock Hazard and Code Compliance

A laboratory or electrical engineering expert is required to assess a thermocouple-based schematic for potential electric shock hazards and regulatory compliance. The scope includes:

• Evaluating whether contact with bare thermocouple wires or associated water poses a shock risk to a grounded individual.

• Providing a demonstrative video or expert testimony, if necessary.

• Reviewing a prior consultant’s report to determine whether it sufficiently addressed safety concerns related to:
  A. Partially deionized water
  B. Lack of galvanic isolation
  C. Presence of unexpected voltages from non-isolated sources
  D. Corrosion concerns affecting thermocouple wire integrity

• Investigating any direct or incidental contact between bare thermocouple wires and non-galvanically isolated energized components (e.g., extension cords, power strips) for shock risk.

• Determining whether the design violates applicable electric safety codes or standards, including IEC, UL, OSHA, NEC, CSA, and NFPA 70E.

• Delivering a detailed report supported by references.

• Willingness to sign a Thermo Fisher Protective Order (NDA).
