Conduit shall be run parallel or at right angles to existing walls, ceilings, and
structural members.
Support branch circuit conduits at intervals not exceeding 10 ft. and within three
feet of each outlet, junction box, cabinet or fitting. Attach individual branch
circuit conduits to structural steel members with spring steel type or beam
conduit clamps and to non-metallic structural members with one hole conduit
straps. For exposed conduits and where conduits must be suspended below
structure, single conduit runs shall be supported from structure by hangar rod
and conduit clamp assembly. Multiple conduits shall be supported by trapeze
type support suspended from structure. Do not attach conduits to ceiling
suspension system channels or suspension wires.
Attach feeder conduits larger than 1" trade diameter to or from structure on
intervals not exceeding 12 ft. with conduit beam clamps, one hole conduit straps
or trapeze type support in accordance with support systems described for branch
circuit conduits.
Exposed conduits shall be painted as specified under the PAINTING section of
the specifications, or as otherwise indicated in the Architectural documents.
Do not install conduits through structural members.

Conduits attached to building construction on opposite sides of a building
expansion joint shall be provided with an expansion and deflection coupling. In
lieu of an expansion coupling, conduits 2-1/2" and smaller may be provided with
junction boxes on both sides of the expansion joint connected by 15" of slack
flexible conduit with bonding jumper.
No conduit installation requiring cutting of cross-webs of concrete masonry units
is permitted. Conduit shall be threaded through cells or concrete masonry units
