ELECTRICAL SUPPORTS AND SEISMIC RESTRAINTS 260072 – 3
a. Metallic Coatings: Hot-dip galvanized after fabrication and applied according to
MFMA-3.
3. Channel Dimensions: Selected for structural loading and applicable seismic forces.
C. Raceway and Cable Supports: As described in NECA 1.
D. Conduit and Cable Support Devices: Steel hangers, clamps, and associated fittings, designed
for types and sizes of raceway or cable to be supported.
E. Support for Conductors in Vertical Conduit: Factory-fabricated assembly consisting of threaded
body and insulating wedging plug or plugs for non-armored electrical conductors or cables in
riser conduits. Plugs shall have number, size, and shape of conductor gripping pieces as
required to suit individual conductors or cables supported. Body shall be malleable iron.
F. Structural Steel for Fabricated Supports and Restraints: ASTM A 36/A 36M, steel plates,
shapes, and bars; black and galvanized.
G. Mounting, Anchoring, and Attachment Components: Items for fastening electrical items or their
supports to building surfaces include the following:
1. Verify suitability of fasteners in subparagraph below for use in lightweight concrete or
concrete slabs less than 4 inches (100 mm) thick.
2. Powder-Actuated Fasteners: Threaded-steel stud, for use in hardened portland cement
concrete, steel, or wood, with tension, shear, and pullout capacities appropriate for
supported loads and building materials where used.
a. Available Manufacturers:
1) Hilti, Inc.
2) ITW Construction Products.
3) MKT Fastening, LLC.
4) Simpson Strong-Tie Co. Inc.
3. In the following subparagraph, use stainless steel anchors in corrosive environments.
4. Mechanical-Expansion Anchors: Insert-wedge-type, zinc-coated steel, for use in
hardened portland cement concrete with tension, shear, and pullout capacities
appropriate for supported loads and building materials in which used.
a. Available Manufacturers:
1) Cooper B-Line; a division of Cooper Industries.
2) Empire Tool and Manufacturing Co., Inc
3) Hilti, Inc.
4) ITW Construction Products.
5) MKT Fastening, LLC.
6) Powers Fasteners.
5. Clamps for Attachment to Steel Structural Elements: MSS SP-58, type suitable for
attached structural element.
6. Through Bolts: Structural type, hex head, high strength. Comply with ASTM A 325.
7. Toggle Bolts: All-steel springhead type.
8. Hanger Rods: Threaded steel.
2.3 SEISMIC-RESTRAINT COMPONENTS:
A. Rated Strength, Features, and Application Requirements for Restraint Components: As defined
in reports by an agency acceptable to authorities having jurisdiction.
1. Structural Safety Factor: Strength in tension, shear, and pullout force of components
used shall be at least five times the maximum seismic forces to which they will be
subjected.
