Frame foundation
A mounting pad must be constructed for proper support
of the switchgear and substation frame. Concrete slabs
can be fabricated by a local concrete products firm. See
the dimensions in the plan and profile views of Figure3.
The overall weight of the substation frame is approximately
118kg (260lbs).
