    BRIEF

    Policy Summary

    The Berkeley Lab Electrical Equipment Safety Program (EESP) is designed to ensure safe operation and installation of electrical utilization equipment. This is achieved by purchasing equipment with a Nationally Recognized Testing Laboratory (NRTL) certification, or through a Berkeley Lab inspection and approval process, with final approval by the Berkeley Lab Electrical Safety Authority Having Jurisdiction (AHJ).

    Who Should Read This Policy

    Any Berkeley Lab employee, subcontractor, or affiliate who purchases or builds electrical utilization equipment for use at Berkeley Lab that has a potential of 50 volts or greater anywhere in the equipment

    Electrical Equipment Safety

    Publication date:

    POLICY

    A. Purpose

    The Lawrence Berkeley National Laboratory (Berkeley Lab) Electrical Equipment Safety Program (EESP) is designed to ensure the safe operation and installation of electrical utilization equipment. This is achieved by purchasing equipment with a Nationally Recognized Testing Laboratory (NRTL) certification, or through a Berkeley Lab inspection and approval process, with final approval by the Berkeley Lab Electrical Safety Authority Having Jurisdiction (AHJ).

    B. Persons Affected

    Any Berkeley Lab employee, subcontractor, or affiliate who purchases or builds electrical utilization equipment for use at Berkeley Lab that has a potential of 50 volts or greater anywhere in the equipment.

    C. Exceptions

    The following types of electrical equipment do not require inspection and approval prior to use:

    1. Unmodified NRTL-Listed Equipment: Equipment that is listed by an NRTL and has not been modified.
    2. Unused Equipment: Equipment that is not being used (e.g., in storage, staged for salvage or excess, etc.). Equipment that is not being used must be labeled with the EQUIPMENT OUT OF SERVICE label (see Appendix B) so it is clear it is not in use.
    3. Equipment Granted Conditional Acceptance Under Work Process E: Prototype or proof-of-concept equipment (e.g., test chassis, benchtop experiment) in the process of being built to test the validity of a design and that is under the exclusive control of the designer if used for less than three months. Equipment being developed that exceeds a three-month period may be acceptable but requires Conditional Acceptance per Work Process E.
    4. Equipment Considered Nonhazardous: Equipment in any of the following categories is considered nonhazardous:


    Note: Equipment that is connected to AC only via a step-down transformer/AC adapter with voltage output less than 50 volts is exempt, but the transformer/AC adapter must be NRTL Listed.

    D. Policy Statement

    1. The Berkeley Lab Electrical Equipment Safety Program (EESP) is designed to ensure the safe operation and installation of electrical utilization equipment. Only electrical utilization equipment that has been approved by the AHJ may be used at Berkeley Lab. Electrical utilization equipment that has been Accepted, Certified, Labeled, or Listed by an NRTL is considered acceptable to the AHJ, and is approved for use provided the equipment is installed and used within the manufacturer's listing intent. Electrical utilization equipment that has NOT been Accepted, Certified, Labeled, or Listed by an NRTL is not acceptable to the AHJ unless it has satisfactorily passed a documented safety inspection. To meet this requirement, Berkeley Lab has established the EESP.
    2. Upon installation, and prior to energization, newly purchased or Berkeley Lab–built electrical utilization equipment:
