H07V-U 1X2.5 and H07V-K 1X4 share the H07 family and PVC insulation description in the imported database, but the conductor descriptions and sizes differ. Compare the complete strings in the Cable Marking Decoder.
Side-by-side comparison
| Input | Family | Construction | Conductor and size |
|---|---|---|---|
| H07V-U 1X2.5 | H07, 450/750 V harmonized cable | PVC insulation, solid conductor | Single 2.5 mm2 conductor |
| H07V-K 1X4 | H07, 450/750 V harmonized cable | PVC insulation, flexible conductor | Single 4 mm2 conductor |
The U and K distinction in this set
The current rows record U as a solid conductor and K as a flexible conductor. That distinction belongs to the exact lookup entries shown here. Do not use one row to rewrite an unrecognized marking from another product family.
Read 1X together with the size
In both current rows, 1X is part of the matched conductor notation and the size follows it. The two entries do not have the same size: one is 2.5 mm2 and the other is 4 mm2.
What a comparison cannot decide
This comparison explains the current reference rows. It does not determine ampacity, installation permission, procurement suitability, or local requirements. Use the product label and data sheet for those decisions.

Imported regional power-cord rows from MicrosoftDocs/azure-docs, harmonized cable marking guides, UL wire and cable marking guidance, and manufacturer cable data sheets; verified 2026-08-30.
- This page is a production database view built from imported rows plus exact cable-marking lookup examples.
- A conductor area or gauge shown in a marking does not determine ampacity by itself.
- Manufacturer-specific suffixes and local code requirements can change the final meaning. Verify the complete product label and data sheet before acting.
- Do not treat this decoder or guide as a safety, installation, procurement, customs, or legal compliance decision.
