NYY-J 5X10 is a supported exact entry in the Cable Marking Decoder. The current lookup keeps NYY, J, and 5X10 as separate evidence rather than treating the complete string as one opaque code.
Segment breakdown
| Segment | Current reference meaning |
|---|---|
| NYY | PVC insulated and PVC sheathed power cable family; national designations vary. |
| J | Includes protective conductor. |
| 5X10 | 5 cores, 10 mm2 each. |
Read J in context
For this exact NYY-J row, the reference data records J as with green-yellow earth or including a protective conductor. That does not mean the same letter has the same role in every cable family. Read the whole matched row.
Read 5X10 as count plus size
The current result returns five cores and 10 mm2 each. Keep the X notation and the size together when entering the marking, and inspect the reference rows for the note attached to the entry.
Boundary of the result
The row is a marking reference. It does not calculate ampacity or replace the full manufacturer specification, applicable local requirements, or professional review.

- 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.
