For seismic safety in California electrical installations, what is the maximum spacing between supports for rigid metal conduit in areas subject to seismic activity?
Correct Answer
D) 6 feet
California amendments to NEC Article 344.30 require closer spacing of conduit supports in seismic areas. The maximum spacing is reduced to 6 feet (compared to 10 feet in non-seismic areas) to prevent damage during earthquake motion and ensure electrical system integrity.
