Remote-Control Signaling and Power-Limited Circuits, Classes 1, 2, and 3: Insulated conductors
in raceway unless otherwise indicated.

3.05 WIRING INSTALLATION
Make splices and taps that are compatible with conductor material and that possess equivalent or
better mechanical strength and insulation ratings than unspliced conductors.
No wires shall be pulled in until the conduit system is complete. Ideal “Yellow 77” or other
approved pulling lubricant shall be used.
3.06 ELECTRICAL SUPPORTING DEVICE APPLICATION
Damp Locations and Outdoors: Hot-dip galvanized materials or nonmetallic, slotted channel
system components.
Dry Locations: Steel materials.
Strength of Supports: Adequate to carry present and future loads, times a safety factor of at
least four with, 200-lb minimum design load for each support element.
3.07 SUPPORT INSTALLATION
Support parallel runs of horizontal raceways together on trapeze- or bracket-type hangers.
Size supports for multiple raceways or cable runs so capacity can be increased by a 25 percent
minimum in the future.
Support individual horizontal single raceways with separate, malleable-iron pipe hangers or
clamps except use spring-steel fasteners for 1-1/2-inch and smaller single raceways above
suspended ceilings and for fastening raceways to slotted channel and angle supports.
Install sleeves for cable and raceway penetrations of concrete slabs and walls unless core-drilled
holes are used. Install sleeves for cable and raceway penetrations of masonry and fire-rated
gypsum walls and of all other fire-rated floor and wall assemblies. Install sleeves during erection
of concrete and masonry walls.
Secure electrical items and their supports to building structure, using the following methods
unless other fastening methods are indicated:
(a) Wood: Wood screws or screw-type nails.
(b) Gypsum Board: Toggle bolts. Seal around sleeves with joint compound, both sides of
wall.
