Attachment R - 26 08 00 - Electrical Shore Ties CSTO (Rev B) - Section 2.4.6 Testing.pdf

This document is a technical specification section for Electrical Shore Ties installation and acceptance testing under Coast Guard contract SILC-CSTO-36-11.

The specification establishes comprehensive requirements for installation, testing, and acceptance of electrical shore tie systems. Key installation requirements include: use of compression lugs specifically designed for DLO cable with oxide inhibitor and heat shrink sleeves; prohibition of Allen screws or mechanical clamps for terminations; rotation clips with single hole lugs to prevent short circuiting; and stud adapters on circuit breakers for landing lugs. All acceptance testing must be performed in the presence of a Coast Guard inspector or Contracting Officer's Representative, with written test reports submitted within one week of completion. Prior to installation, all new electrical equipment undergoes inspection to identify and remedy any damage. The specification mandates conductor color coding standards for different voltage systems (450V Delta, 230V Delta, 480V/277V, and 208/120V), with detailed insulation resistance testing requirements using a direct current megohmmeter at voltages specified by operating voltage ranges. Minimum acceptable insulation resistance values are established for lighting, power, instrumentation/control, and audio/telephone circuits across three temperature ranges (40°F, 70°F, and 140°F). Additional acceptance testing includes conductor resistance tests for load division verification, operability testing, clearance checks, enclosure tightness testing with water hose nozzles at 50 psig pressure, and electrical system acceptance testing using resistive/reactive load banks at power mounds.
