The National Electric Code (NEC) specifies a minimum radius for conduit bends in order to avoid damage to both the conduit and conductors. The code further specifies that the total of all bends in a conduit run must not exceed 360°.
The NEC specifies in Chapter 9, Table 2 the minimum radius to the center-line of the conduit of other bends must be no less than the values listed in the table.

Saddles are typically used to route conduit around obstructions such as existing ductwork or piping. A saddle can have 1-4 bends depending on the need.

The National Electric Code (NEC) specifies the minimum size for cable tray systems which includes ladder, ventilated trough, ventilated channel, solid bottom and other similar structures. It’s important to note that cable trays are mechanical support systems and not raceways. Raceways are included in another section of the code.

Proper cable tray sizing is complicated and often existing cable trays are overloaded per the code. If you have questions or would like some engineering assistance to properly size your cable tray installation please contact us.
