Restraining Electrical Equipment
Restraints are used to prevent equipment and systems from moving horizontally, vertically, or from turning over. The purpose of restraining is to prevent equipment from damaging itself (rendering it non-functional) or damaging adjacent systems that need to remain operational during an Extreme Event. The restraint or anchoring systems must provide a direct load path to the main structure of the building. In all cases, the use of gravity and friction are not acceptable forms of restraint.
Typical equipment will include transformers, switch gears, motor control centers, bus ducts, cable trays and electrical panels.
Seismic Spring Isolators Our restrained spring type isolators with housings are designed to prevent excessive equipment movement due to seismic and wind forces. |
||
Seismic Restraint Brackets Our standardized seismic equipment restraint brackets save installation time and effort and match a variety of equipment base styles. |
Pads Type N and NSN neoprene rubber pads can be cut to specific sizes to match loading conditions. Type RD neoprene mounts include a threaded insert for attachment. Both options provide effective high frequency isolation on stiff structures. |

| Component | Design Considerations | |
|---|---|---|
Indoor base mounted | Anchor equipment to housekeeping pads, keeping in mind anchor edge distance and anchor embedment depth |  |
| Ensure that housekeeping pads have been reinforced and positively attached to the building structure for the designed equipment’s seismic and overturning loads | ||
| Verify that housekeeping pads have adequate depth for anchor embedment | ||
| Establish that restraint brackets are adequately attached to the equipment | ||
| Vibration control products shall be seismically rated and should not affect the restraint system | ||
| Cable trays and bus ducts | The restraint system needs to be attached to the building structure |  |
| Confirm that restraint anchor location (wall, beam, column or slab) can withstand seismic load | ||
| Anchors need to be seismically approved |
