Specific cable / buyer evidence

Read the whole cable rating, not just one letter

A familiar type suffix or an XLPE/PVC description is a starting point for identification, not a complete cable rating. UL notes that markings can appear on cable, marker tape, reel tag or carton. Record the actual text and the source of each claim rather than filling gaps from a generic type decoder.

Submit cable details
Distinct buyer question

Separate exact type, voltage, wet/dry, jacket material and tag evidence for a surplus reel.

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.

FieldDocumented example / boundarySource
Where markings appearUL says some required information can reside on cable, under a sheath, on a tag/reel or smallest container.[1]
Wet-location wordingUL identifies explicit “WET,” “WET LOCATION” or “90C Wet or Dry” product markings as relevant evidence.[1]
Material-level propertyLAPP’s PVC and XLPE breakdown-voltage values are kV/mm material data—not a finished cable nameplate voltage.[2]
Multiple type namesUL explains that a product marked with multiple Type designations was evaluated for the uses of those marked Types.[1]

Write what the offered cable actually states

A correct transcription keeps THWN-2, RHH/RHW-2 or another type string, the voltage and any temperature/wet/dry qualifier together. A partly unreadable sequence should remain qualified as missing evidence. Ask for the corresponding reel tag and exact manufacturer datasheet, including a product number.

  • Photograph several full print repeats; show voltage units and type modifiers.
  • Record insulation and jacket material only when the actual product record supports them.
  • Do not infer 1000 V, direct burial, sunlight or a temperature from a jacket color.

Keep material science apart from nameplate ratings

An insulation-material property chart compares polymers under specified test conditions. It does not assign finished-cable voltage, current capacity or listing status. Other layers, thickness and product evaluation matter; do not use a material abbreviation as a substitute for the offered reel’s print.

  • Identify whether a statement came from a cable label, reel tag, maker sheet or generic materials chart.
  • Present no installation, code-compliance or acceptance decision.

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.
