Question: I have 4/0 box attached to a 3/4 rigid conduit that is supported 3 ft. from the box is more support required. This for a motion sensor

If I remember correctly I believe you need two conduits to support a Box

See 314.23... Most likely 314.23(E) of 314.23(F)

The only time a raceway can support a box is when the box has threaded hubs. 4" box requires it's own support.
