Circuit and disconnect marking survey

Use it with your own records.

1. Download the workbook and open 12 Circuit markings.
2. Enter your site and room scope and the project or policy reference.
3. Use the blank amber table for actual records. The fictional example below it is a reference.
4. Insert table rows when needed. Keep identifiers as text, including leading zeros.
5. Follow guide 12 to complete the checks and record unresolved items.

Before you start

1. Define whether the task covers equipment source text, a disconnect purpose marking, a directory entry, or another specific marking object, and list the included equipment.
2. Collect the equipment register, current drawing and circuit schedule references, marking policy, and the electrical reviewer responsible for the accepted disposition.
3. Establish the permitted observation method and explicitly identify markings or areas that cannot be examined within that scope.
4. Prepare evidence references that connect both the visible wording and its physical marking object to the supplied equipment under review.

Complete the register

1. Enter the supplied Equipment ID separately from the panel or disconnect entered under Marking object; do not substitute one identity for the other.
2. Record the full location and enough physical context to distinguish the marking from similar labels on nearby equipment.
3. Transcribe Observed purpose exactly, including omissions, damage, or partial text. Preserve uncertain characters rather than reconstructing them.
4. Enter the documented relationship with its parent board or disconnect, circuit or suffix where provided, and the actual source revision.
5. Write the Finding as a precise comparison of observed and documented values, or as a clearly bounded missing-information condition.
6. Assign the electrical reviewer and retain proposed action separately from the accepted Disposition. Link any text and document changes to that decision.
7. Add the final observation evidence only after the accepted work is complete and record which specific marking comparison it supports.

Walk through the example

For DISC-G12-301 in DC01 / H1, enter CDU-G12-301 as the supplied equipment and DISC-G12-301 as the marking object. Record the observed purpose as missing, while retaining the separate fact that the disconnect asset sticker is readable. In Documented reference, cite ELEC-G12-301 revision 2 and its stated supplying relationship. Mark the row awaiting electrical review and link the context observation. When the owner issues DEC-G12-301, enter that decision and the accepted purpose text without overwriting the original missing-text finding. After CH-G12-301 is completed through the appropriate process, attach EV-G12-302 showing the disconnect identity and final face. The reviewer compares that evidence with the decision and enters the real review date. This closes the stated purpose-marking discrepancy. It does not claim the survey inspected inaccessible equipment or established an electrically safe work condition. Retain the missing-purpose observation as the before-state so the closed row explains why the accepted face was required.

Handle common exceptions

A circuit number is readable but its parent board is absent.

Preserve the partial text and ask the electrical reviewer to establish the complete source reference before releasing a correction.

The current schedule and drawing disagree.

Record both document identifiers and revisions, explain the exact conflict, and keep the accepted relationship unresolved pending owner disposition.

The corrected text is visible but the photo omits the object identity.

Retain the photo as text evidence and obtain accepted contextual evidence connecting it to the surveyed marking object before closure.

Review and close

1. Check that the final face belongs to the same marking object identified in the finding and identifies the intended supplied equipment.
2. Compare the complete final wording with the accepted disposition, including parent source references and circuit suffixes.
3. Confirm any required record revision is linked and distinguish original observation, owner decision, and final installation evidence.
4. Keep unresolved source questions assigned to the electrical owner rather than closing them through a proposed label value.
5. Enter the actual identity-review date and describe the survey scope without implying authority to operate equipment or assess electrical safety.
