Which identities should the drawing distinguish?
Keep the rack PDU identity, physical outlet label, electrical bank or circuit, and any logical control group in separate fields. A drawing can use one identifier while a management interface uses another. Do not assume identical numbering means the two records describe the same boundary.
Schneider Electric's switched rPDU troubleshooting FAQ distinguishes bank circuit breakers from outlet enablement indications. That model-family example supports checking the selected equipment arrangement. It does not establish a universal bank layout or give permission to switch an outlet.
Critical Power Drafting is independent and is not affiliated with Schneider Electric. Use the actual current manual and approved project design. Engineering sign-off is performed only by the registered engineer on the job.

Which fields belong in an outlet mapping worksheet?
Create one row per physical outlet in the scope of the drawing review. Preserve the manufacturer outlet labels exactly and retain the source revision. If the model evidence does not identify a bank, leave that mapping unresolved.
| Field | Source to record | Check |
|---|---|---|
| Rack and PDU | Project equipment schedule | Which physical PDU is being described? |
| Physical outlet | Actual manufacturer outlet identifier | No inferred renumbering |
| Electrical bank | Selected model bank diagram | Bank mapping is supported by that model |
| Protective device | Approved bank protection reference | No assumed rating from an adjacent bank |
| Incoming supply | Controlled single-line and circuit schedule | Upstream reference resolves to this PDU |
| Logical control group | Management configuration reference if relevant | Control grouping stays separate from circuit identity |
| Connected load reference | Approved cable or equipment schedule | Documentation covers the intended connection |
How can two labels conceal a mismatch?
Illustrative example. A fictional PDU-DEMO labels a physical receptacle Outlet 05. Its approved model drawing places that outlet in Bank B, while a configuration export calls a control group Group 1. A draft cable schedule records Outlet 05, Bank 1 because the writer copied the control-group number. The mismatch is a drawing query; the group number does not establish the electrical bank.
Record the model drawing, configuration export and affected cable schedule revision together. Ask the drawing owner to confirm the mapping. Do not change the live configuration, operate a breaker or move a load to make the documentation appear consistent.
When a PDU model is substituted, reopen the mapping rather than keeping the previous bank relationships. An unchanged rack name or similar-looking enclosure does not establish identical internal grouping.
What should be checked before issuing the drawing pack?
Follow each physical outlet back to the approved model evidence, then follow each incoming PDU supply to the controlled circuit schedule. Record missing links and ambiguous labels at the correct equipment level. A complete list of outlet numbers can still have an unresolved bank or supply reference.
Keep A and B project supply labels tied to the approved design. Labels alone do not prove independence, capacity or redundancy. This worksheet documents identity and references; load assessment and electrical design remain separate technical work.
Retain a revision note explaining approved mapping changes. A later reviewer should be able to distinguish a corrected label from a changed equipment arrangement. No installation, switching or energization is authorised by this drawing guide.
Common questions
What else should the bid team know?
Is an outlet control group the same as a protective bank?
Do not assume that. Check the selected model and retain separate identifiers.
Can the previous mapping be kept after a model substitution?
Only where the actual new equipment evidence and approved review support it.
Does an outlet map prove spare electrical capacity?
No. Capacity and design checks require their own authorised assessment.
