Cable Tray Fitting Radius Selection Table
Cable Tray Fitting Radius Selection Table lookup table with assumptions and boundary notes.
Scope
Cable tray fitting planning only. Cable bend limits, tray series, fitting catalogue data, and installation conditions govern actual radius selection.
Lookup table
Compare common cable tray fitting radius labels and cable outside-diameter multiplier source links.
Scroll sideways to keep row labels aligned with hidden columns.
| Fitting type | Typical radius lookup | Example at 30 mm cable OD (mm) | Boundary |
|---|---|---|---|
| Horizontal elbow | 9x cable OD | 270 | radius planning only; cable bend limit and tray fitting catalogue govern actual selection |
| Vertical inside elbow | 12x cable OD | 360 | radius planning only; cable bend limit and tray fitting catalogue govern actual selection |
| Vertical outside elbow | 12x cable OD | 360 | radius planning only; cable bend limit and tray fitting catalogue govern actual selection |
| Horizontal tee | 9x cable OD | 270 | radius planning only; cable bend limit and tray fitting catalogue govern actual selection |
| Horizontal cross | 9x cable OD | 270 | radius planning only; cable bend limit and tray fitting catalogue govern actual selection |
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.
