mV/A/m cable data sources
Record fields for mV/A/m cable data used in Australian voltage-drop worksheets without publishing controlled cable table values.
Evidence to capture for mV/A/m cable data
Show which source fields should travel with an entered mV/A/m value without replacing the governing cable data source.
| Field | Record | Source | Boundary |
|---|---|---|---|
| mV/A/m value | Entered voltage-drop data value used by the calculator. | Project, product or standards-review source | The public table does not publish cable-data values. |
| Cable label | Metric size, conductor material and cable type tied to the value. | Cable schedule or product data | Do not reuse a value across a different cable context. |
| Installation basis | Installation method, grouping and route context noted with the value. | Design note or governing source | Installation conditions can change the applicable data. |
| Temperature basis | Ambient or conductor-temperature assumption where the source states it. | Source note or project assumption | Temperature correction is not inferred by this table. |
| Source revision | Edition, datasheet revision or project note date. | Document control record | A stale source should be rechecked before reuse. |
- Use this table to make entered cable data traceable.
- Calculator results are only as strong as the source value entered.
How mV/A/m evidence supports voltage-drop work
Record where the entered mV/A/m value came from so voltage-drop results can be reviewed against the cable family and installation context.
| Item | Value |
|---|---|
| Purpose | Show which source fields should travel with an entered mV/A/m value without replacing the governing cable data source. |
| How to use the source | Field table only; mV/A/m voltage-drop arithmetic lives on the calculator and formula chart. |
| Standards and project context | AS/NZS 3008 context noted for project review; verify current source documents before applying entered values. |
| Where judgement is still needed | Use this table for lookup, labelling or worksheet context; do not treat it as a project-specific calculation result. |
| Before relying on it | Confirm current standards, local authority requirements, DNSP conditions, project documents and manufacturer data before relying on a decision. |
Project source basis for cable data
Keep the cable data source, checked date and product context visible whenever a calculator uses the entered value.
| Item | Value |
|---|---|
| Source | AUWiring voltage-drop calculator field model and Australian cable-data record practice. |
| Source type | Project or product record model |
| Derivation basis | AUWiring field table for sourced cable-data records; no AS/NZS cable table values are reproduced. |
| Last checked | 2026-07-13 |
| Review interval | Annual or when voltage-drop calculator fields, cable-data practice or standards context changes. |
| Review trigger | Calculator field change, cable-data source change, standards update or project feedback. |
| Version used | R04-2026-07-13 |
| Australian application | Australia; project, cable product, installation method, temperature and governing source can change the value used. |
