Installation of Bottom Entry Conduits
Conduits can be stubbed in after the location of the
motor control center lineup has been established. Conduit
should be stubbed approximately 2 inches (51mm)
above the finished floor line. Figure 6 and Figure 7 show
the conduit entrance space available at the bottom of
standard sections. Exceptions to this available space rule
are indicated on drawings furnished by GE for specific
installations. Center the conduit beneath the section
vertical wireway to facilitate direct cable entry. Note:
Bottom rear entrance should only be used with full
rear accessibility.
