Question

When running conduit...How far apart should the supports be?

Answer 1

The number of supports needed depends on the type of conduit being used. Holes or notches in framing members may serve as supports.

EMT requires supports within 3 feet of each outlet box, junction box, cabinet, or fitting and every 10 feet thereafter.

Rigid-steel conduit must also be supported within 3 feet of a box. The distance between supports may be increased to 20 feet on direct vertical runs of rigid-steel conduit from machine tools and other equipment if threaded couplings are used and the riser is supported at each end.

Answer 2

It varies with the size, type and direction.  In general, support within 3 feet of the box and then no more than 10'  between supports.  Larger conduit and vertical runs may vary.
