Identify marked solar PV wire separately from generic solar cable and undocumented reel exposure.
Checkable specification fields
These are examples from the named references, not assertions about a reel you have not shown us. Match the actual jacket, tag and part number before using a product claim.
| Field | Documented example / boundary | Source |
|---|---|---|
| Southwire example | A cited aluminum Type PV construction has XLPE insulation, 2000 V marking and sizes from 6 AWG to 1000 kcmil. | [1] |
| Sample print | The maker’s sample legend includes PV WIRE, 2000V, 90°C WET OR DRY, SUN RES and sequential footage. | [1] |
| Standards distinction | UL identifies UL 4703 PV wire separately from UL 9703 distributed-generation harnesses. | [2] |
| Limit of observation | A SUN RES marking on a documented product does not establish the present life or integrity of a weathered surplus reel. | [1] |
Read, then match, the physical legend
Photograph several legible points on the outer layer and the reel label. Compare the whole line—including metal, size, date, wet/dry and voltage—to the exact manufacturer sheet. Do not copy this aluminum product’s rating to a copper reel, harness assembly or different manufacturer.
- Transcribe product designation and any UL reference as printed, not as a certification conclusion.
- Capture conductor metal/size, original reel ID, sequence marks and both end seals.
- Keep actual warehouse/outdoor exposure and visible UV or handling effects in a separate condition field.
Decide what the evidence cannot say
A product design claim and a current reel inspection answer different questions. Record duration of storage if known, open ends, broken flanges, kinks or crushed outer wraps. If history is unavailable, say so; neither appearance nor a dated manufacturer sheet proves current electrical suitability.
- Ask for photos of flange edges, cable ends and tag.
- Do not promise resale, installation, testing or compliance outcomes.
Source notes and scope
The linked references support the specific examples above. Product designs and standards can change; seller-supplied markings, measured length and current condition require separate verification. Nothing here states that this buyer stocks, tests, guarantees or accepts a particular cable, or offers installation advice.
