old SO cable

[junkhound]

I have about 60 ft of old SO 4/4 cable with cracked outer sheath (in many places), I plan to use it by installing in 1-1/4" PVC conduit, all a straight run. No damage to any internal conductor insulation and not brittle either, just the outer jacket turned brittle.

Derate of course.

Can anyone quote a code section that prohibits this?

A basic prohibition for cords in raceways.

400.12 Uses Not Permitted. Unless specifically permitted in 400.10, flexible cords, flexible cables, cord sets, and power supply cords shall not be used for the following:
(1) As a substitute for the fixed wiring of a structure
(2) Where run through holes in walls, structural ceilings, suspended ceilings, dropped ceilings, or floors
(3) Where run through doorways, windows, or similar openings
(4)Where attached to building surfaces
Exception to (4): Flexible cord and flexible cable shall be permitted to be attached to building surfaces in accordance with 368.56(B) and 590.4.
(5)Where concealed by walls, floors, or ceilings or located above suspended or dropped ceilings
Exception to (5): Flexible cords, flexible cables, and power supply cords shall be permitted if contained within an enclosure for use in other spaces used for environmental air as permitted by 300.22(C)(3).
(6)Where installed in raceways, except as otherwise permitted in this Code

If the sheathing is cracked it's time to scrap it as it is beyond the useful life of the cable, besides Infinity's comments.

OK, will use as welding cable extensions, 4 parallel 4AWG would be good for that.
