| Cable family | Lookup multiplier | Example at 20 mm OD (mm) | Boundary |
|---|---|---|---|
| Armoured cable | 6x cable OD | 120 | Planning planning only; cable markings and manufacturer instructions govern bends |
| Portable/flexible cable | 6x cable OD | 120 | Planning planning only; cable markings and manufacturer instructions govern bends |
| Large power cable | 8x to 12x cable OD | 160 to 240 | Planning planning only; cable markings and manufacturer instructions govern bends |
| Manufacturer-specific cable | Use product data | product data | Planning planning only; cable markings and manufacturer instructions govern bends |
Notes
- Check table values for preliminary lookup and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
