Open, Inspect, Report of Circuit Breaker

Statement of Work (SOW) / Performance Work Statement (PWS)

This specification outlines the requirements for the repair of electronic equipment and modules, aiming to return them to a "Ready for Issue" (RFI) condition from a "Non-Ready for Issue" (NRFI) state.

• Covers the repair of complete assemblies, subassemblies, circuit card assemblies, power supplies, modules, and other specified components.

• Includes disassembly, cleaning, repair or replacement of parts, installation of field changes/firmware upgrades, re-assembly, alignment, and testing.

• Specifies that the contractor will provide all necessary spare parts, technical manuals, and consumable materials.

• Repairs must return equipment to an operational status.

• Three levels of inspection are required: incoming, in-process, and final.

• Testing includes operational tests and final performance/acceptance testing using mock-ups or Automated Test Equipment (ATE).

• Fault isolation procedures are required to identify and address the root cause of malfunctions.

• Repairs will generally not be authorized if the cost exceeds 65% of the item's acquisition cost.

• Not explicitly defined in this document, but implies work performed by the contractor.

• Contractor must use OEM parts or parts that equal or exceed OEM specifications.

• Nonstandard parts require Contracting Officer approval.

• Contractor must obtain required technical specifications and manuals.

• Contractor must affix a permanent vendor identification decal.

• All repaired items must be individually packaged, marked according to specified military standards (MIL-STD-2073-1E, MIL-STD-129), and include a copy of the test data record sheet.

• Sensitive electronic devices require specific protection measures.

• Calibration of test equipment must be traceable to the National Bureau of Standards.

Statement of Work (SOW) / Performance Work Statement (PWS)

This document describes the requirements for the inspection, overhaul, and testing of circuit breakers for the purpose of SFLC stock replenishment. The goal is to restore the circuit breakers to a condition equivalent to that of a new circuit breaker.

• Perform inspection, overhaul, and testing of circuit breakers.

• Ensure delivered circuit breakers are complete units; report any missing components or questionable conditions.

• Restore circuit breakers to a condition equal to that of a new circuit breaker.

• Disassemble and thoroughly clean all components using manufacturer-approved solvents and lint-free cloths.

• Repair or replace worn or damaged parts beyond manufacturer tolerances using only OEM parts.

• Perform detailed inspections, including arc chutes and primary/secondary disconnects.

• Inspect electrical switches, solenoids, relays, wiring, and motors for wear and damage.

• Conduct insulation resistance tests on control wiring.

• Verify operation of spring charging motors and cutoff switches.

• Fully assemble, calibrate, and test overhauled circuit breakers.

• Overhaul is intended to restore the circuit breaker to a condition equal to that of a new circuit breaker.

• All testing shall be witnessed by a Coast Guard Quality Assurance Representative (QAR).

• Testing shall be performed on contractor-supplied calibrated test equipment.

• Failed circuit breakers must be repaired and re-tested until successful.

• Specific tests include mechanical operation, insulation resistance, pole resistance, overcurrent trips, and dielectric tests as per ANSI/NEMA AB4.

• Warranty: Standard manufacturer's warranty applies, with an additional guarantee against defects leading to failure for 90 days after installation for up to two years after delivery.

• Overhaul and testing services are to be performed at the contractor's plant.

• Preservation is for warehouse storage, not immediate installation.

• Preservation is required for a period of two years minimum.

• Contractor must notify the Coast Guard Contracting Officer of any missing components or questionable conditions.

• Contractor must immediately notify the Coast Guard Contract Administrator if circuit breakers received do not match the specified part number.

• A detailed estimate for overhaul and testing must be submitted for approval prior to starting work.

• Technicians performing shipboard assessments and testing ashore must be employed by the original equipment manufacturer or an accredited firm (NETA).

• A written report detailing defective parts, OEM part numbers, labor hours, and costs must be submitted.

• Only OEM parts are acceptable for replacement.

• All test equipment must be calibrated and traceable to National standards.

• Overhauled breaker assemblies must be delivered completely assembled and ready for installation.

• Contractor must maintain a documented Quality Control (QC) Program conforming to ANSI/ASQ Q9001-2008.

• Preservation, packaging, and marking must comply with specified standards (MIL-STD-2073-1 E, MIL-STD-129R, etc.).

• Acceptance will be made at destination by a Government representative.
