Inspection Details

Record the gear, panel, machine, or assembly identifier being inspected.
Verify the latest approved schematic, wiring diagram, or control drawing is available and matches the assembly under inspection.
Document when the verification was performed.
Record the inspector and confirm they are a qualified person or competent person as required by site procedure.

Point-to-Point Wiring Verification

Verify each control conductor is landed on the correct terminal and matches the schematic from source to destination.
Verify terminal designations and wire markers are present, legible, and correspond to the wiring schedule.
Check for crossed wires, reversed polarity where applicable, omitted terminations, or incorrect landing points.
Record the number of circuits tested and verified by continuity or equivalent point-to-point method.
Confirm no unintended continuity, short circuit, or cross-connection exists between unrelated control circuits.

Terminal Connections and Termination Quality

Verify all terminations are mechanically secure and installed per manufacturer instructions.
Check that conductor insulation is stripped to the correct length and no bare conductor is exposed outside the terminal.
Verify conductors are routed neatly, protected from abrasion, and not strained at terminals.
Confirm terminal torque was applied per manufacturer specification or documented torque procedure.
Inspect for loose strands, nicked insulation, pinched conductors, or other termination defects.

Accessory Device Function Checks

Verify accessory devices actuate as intended when the control circuit is tested.
Verify visual indicators illuminate or clear according to the control logic.
Confirm manual and field-operated devices change state properly and are wired to the correct terminals.
Verify auxiliary contacts, permissives, and interlocks perform the intended logic and do not bypass safety or control functions.

Safety, Documentation, and Release to Energize

Confirm lockout-tagout controls were used where required before any testing or access to energized parts, consistent with site procedure and OSHA 1910.147.
Verify meters, continuity testers, or other instruments are appropriate for the task and in good working order.
Record all non-conformances, corrective actions, and any components removed from service or held for rework.
Final disposition confirming the control wiring verification passed and the assembly may be energized.
Inspector signs to confirm the verification was completed and findings are accurate.
