Electrical Equipment Safety Program

(EESP)

Only electrical equipment that has been approved by the Authority Having Jurisdiction (AHJ) may be used at Berkeley Lab. Electrical utilization equipment that has been accepted, certified, labeled, or listed by a Nationally Recognized Testing Laboratory (NRTL) is considered to be acceptable to the AHJ, and is approved for use within the manufacturer’s listing intent.

Electrical utilization equipment that has NOT been accepted, certified, labeled, or listed by an NRTL, or has been modified, is not acceptable to the AHJ unless it has satisfactorily passed a documented safety inspection.

The EESP is designed to facilitate safe operation and installation of electrical equipment.

Program Guide 01

Revision 2.00

Procurement is responsible for ensuring that all purchase orders and contracts include language requiring NRTL-Listed equipment as a first consideration.

If a vendor notifies the buyer that the product is not NRTL Listed, the requestor must:

• specify an alternate product, if possible.
• notify the EESP Manager to evaluate options and arrange for an inspection upon arrival and prior to use.

Surveying is identifying and documenting non-NRTL electrical equipment into the EESP database so that an inspection can be performed. All electrical equipment that is not NRTL-labeled must be surveyed.

Divisions are responsible for surveying their own equipment, and may designate as many surveyors as necessary. Surveyors are required to take course EHS0381.

Exceptions

EESP Equipment

Survey Database Barcode

• Unmodified NRTL-Listed Equipment.
• Unused Equipment. Equipment that is not being used, e.g., in storage, staged for salvage or excess, etc. and labeled with the EQUIPMENT OUT OF SERVICE label.

Inspections follow the requirements of NFPA 791, Recommended Practice and Procedures for Unlabeled Electrical Equipment Evaluation.

A Third-Party Field Evaluation may be required for complex equipment.

Additional specific design or performance criteria that are part of the inspections are found on the reverse side.

Equipment inspections result in:

• Pass – No further action required.
• Conditional Acceptance – Equipment may be used for up to 120 days while repairs are scheduled/completed.
• Fail – Equipment must be taken out of service.

Additional criteria is found on the reverse side.

• Equipment Granted Conditional Acceptance under PUB3000, Chap 14, Work Process E.
• Equipment less than 50V, or less than 5mA.

Inspection Result Criteria

Risk Rankings

Electrical equipment inspections result in labeling of the equipment with the following:

Design and Performance Criteria

Unlisted electrical equipment is categorized according to the following risk ranking:

• High Risk: All Unlisted equipment not covered under the medium- or low-risk categories below.
• Medium Risk: Unlisted, commercial 120-240 VAC, unmodified cord-and-plug products certified by the manufacturer to recognized standard without NRTL listing (includes CE).
• Low Risk: Unlisted equipment:
• CS Listed, commercially available, unmodified cord-and-plug products, any voltage
• Unlisted, commercial 120-240 VAC, unmodified cord-and-plug products certified by a Japanese, Australian, or European manufacturer to recognized standards without NRTL listing (includes CE).
• Unlisted equipment supplied by reputable manufacturers.

Fail – Equipment must be taken out of service until repairs are completed.

Pass – Not further action required.

Conditional Acceptance – Equipment may be used for up to 120 days while repairs are scheduled/completed. If repairs are not completed within this period, the equipment is failed and must be taken out of service until repaired.

THESE LABELS ARE PLACED UNDER MANDATE OF THE AHJ, AND MAY NOT BE REMOVED EXCEPT BY THE AHJ OR SALVAGE PERSONNEL.

FAILURE TO COMPLY WITH THESE REQUIREMENTS MAY RESULT IN EQUIPMENT BEING REMOVED FROM SERVICE BY THE AHJ.

The inspector will determine, based on the type of equipment being inspected, which primary standard is most applicable to be used in conjunction with NFPA 791. These primary standards include:

• NFPA 70, National Electrical Code
• NFPA 79, Elec Standard for Industrial Machinery
• UL 508, Industrial Control Equipment
• UL 508A, Industrial Control Panels
• UL 60950-1, Standard for Safety, IT Equipment – Safety; Part 1: General Requirements
• UL 61010-1, Standard for Safety, Electrical Equipment for Measurement, Control, and Laboratory Use, Part 1
