ELECTRICAL TEST LOW VOLTAGE CABLES

Visual and Mechanical Inspection of Low Voltage Cables

• Inspect cables for physical damage and proper connection in accordance with single line diagram.
• Cable connections shall be torque tested to manufacturer’s recommended values or values recommended in P-000.
• Verify proper terminals and crimping die are used on cable and that crimping procedure is proper.
• Verify cable color codintestg or phasing.

Electrical Tests Low Voltage Cables

1. Perform Megger Test on each cable with respect to ground and adjacent cables. For cables 250 volt and less use 500 volt megger; for cables above 250 volt to 600 volt use 1000 volt megger; for cables above 600 volts and less than 1200 volts use 2500 volt megger.
2. Perform continuity test to insure proper cable connection.
