Product Manual B

2. Mounting 5-2019

2. Anchors must be installed to an embedment depth, as recommended in the prequalification test

report defined in Note 1. For IBC 2000 and IBC 2003 applications, the minimum embedment must be

8 times the anchor diameter.

3. Anchors must be installed in a minimum of 4000 PSI compressive strength normal weight concrete.

Concrete aggregate must comply with ASTM C33. Installation in structural lightweight concrete is not

permitted unless otherwise approved by the structural engineer of record.

4. Anchors must be installed to the maximum torque specification, as recommended by the anchor

manufacturer.

5. Anchors must be installed in the locations specified on the Installation Outline Drawings or on

Seismic Requirements Installation Drawing 0179-5288.

6. Wide washers must be installed at each anchor location between the anchor head and the

equipment for tension load distribution. Wide steel washers must be Series W of American National

Standard Type A plain washers flow carbon steel washers), ANSI B18.22.1- 1965, R1975, with the

washer sizes specified on drawing 0179-5288 (Switch Installation; Seismic Requirements, sheet 2 of

3).

7. Concrete floor slab and concrete housekeeping pads must be designed and rebar-reinforced for

seismic applications, in accordance with ACI 318.

8. All housekeeping pad thicknesses must be designed in accordance with the prequalification test

report, as defined in Note 1 or a minimum of 1.5 times the anchor embedment depth, whichever is

largest.

9. All housekeeping pads must be dowelled or cast into the building structural floor slab and designed

for seismic application, as per SCI 318 and as approved by the structural engineer of record.

10. Wall mounting equipment must be installed to a rebar-reinforced structural concrete wall that is

seismically designed and approved by the engineer of record to resist the added seismic loads from

components being anchored to the wall.

11. Floor mounted equipment (with or without a housekeeping pad) must be installed to a rebar-

reinforced structural concrete floor that is seismically designed and approved by the engineer of

record to resist the added seismic leads from components being anchored to the floor.

12. When installing to a floor or wall, rebar interference must be considered.

13. Attaching seismic certified equipment to any floor or wall, other than those constructed of structural

concrete and designed to accept the seismic loads from said equipment, is not permitted by this

specification.

14. Attaching seismic certified equipment to any floor constructed of light weight concrete over steel

decking is not permitted by this specification.

15. Attaching seismic certified equipment to any concrete block walls or cinder block walls is not

permitted by this specification.

For special switch installation requirements, see written and tabulated seismic requirements listed

on drawing 0179-5288.

The installation of the seismically certified switch should be overseen by the installation project structural

engineer of record.

The Site Specific Requirements listed on page one of the "Seismic Certificate of Compliance" should be

filled out by the installation project structural engineer of record.

Drawing 0179-5288 and the Seismic Certificate of Compliance for transfer switch and seismic installation

requirements are included in the literature package of each seismically certified switch with feature code

A080-7.
