Connect bus duct sections with cable

[andrew1]

Would it be okay to connect two bust duct sections with cable? The bus duct and cable conductors would have the same ampacity ratings.

Design would be:

Overcurrent protection----bus duct----tap box----cable----tap box----bus duct

I have looked through the NEC and did not find anything contradicting that this is acceptable. Does anyone have any experience with a similar design or knowledge of its acceptance?

Not a problem. Have done this many times over the years to span expansion joints, change elevation, or provide an offset.

I agree with Jim. We've using the bus duct for accessible vertical portions of the run and conduit and wire for horizontal portions where it was inaccessible after installation.
