recessed steel channels be installed to support the switch-gear.
The floor channel sills under the front, center, and rear of the
switchgear base should be embedded in a level concrete slab with
their top surfaces flush with the finished floor.
While the equipment base center channel is not anchored to the
foundation, it is still required that the center channel sill (see Fig. 4-4)
be level with the foundation and also with the front and rear
channel sills to prevent structural distortion of the switchgear
equipment.
Only four anchor bolts are normally used for outdoor enclosures.
NOTE: The factory must be consulted for anchoring
recommendations for equipment subject to operational and/or
environmental (seismic) shock loading.
NOTE: Si l’équipement doit être assujetti à une charge de choc
opérationnelle ou environnementale (sismique), il faut consulter
le manufacturier afin d’obtenir des recommandations d’ancrage.
Anchor bolts and channels are to be provided by the purchaser; the
clamp plates (Fig. 4-5) are supplied with the equipment.
It is recommended that the anchor bolts be 5/8-inch diameter.

4-2 Assembly and Installation of
Switchgear Equipment
General Requirements
Before assembling or installing the switchgear equipment, all
components should be available at the site location. This will
facilitate switchgear component identification as well as
installation. The foundation should be prepared in accordance with
the instructions in Sections 4-1 and 4-2, and all embedded conduits
installed and capped.
NOTE: If rollers are to be used for movement of the equipment
to its permanent installation, it is recommended that the
shipping skid not be removed until the equipment is placed in
position over the anchor bolts.
NOTE: Au cas où l’utilisation de rouleaux s’avérerait nécessaire
afin d’apporter l’équipement à son emplacement permanent,
nous recommandons que l’emballage d’expédition ne soit pas
enlevé tant que l’équipement n’est pas positionné au dessus
des boulons d’ancrage.
If a transformer is not part of the installation, and/or the equipment
has been split for shipment, place the center section on the
foundation first. Assemble the remaining sections outward from the
center section, in each direction.
If the switchgear equipment is part of a Load Center Unit
Substation, the transformer section should be set on its pad first in
accordance with the instructions furnished with the transformer. All
remaining sections of the switchgear should then be installed.
NOTE: Before assembling and installing the switchgear
equipment, the foundation must be absolutely level and clear of
debris to prevent damage and possible misoperation of the
switchgear equipment.
NOTE: Il faut avant de procéder à l’assemblage et à l’installation
s’assurer que la fondation soit absolument au niveau et
exempte de débris afin de prévenir des dommages à
l’équipement du dispositif de commutation.
