Securing a Motor Control
Center
Documentation packages shipped with assembled MCCs include an MCC
elevation drawing showing an MCC floor plan layout. To secure a column to the
foundation, refer to the provided floor plan layout and the following procedures.
Refer to
for cable and conduit routing instructions.
Securing Methods
MCC columns or shipping blocks can be bolted or welded to a foundation. Two
mounting channels on the bottom of each MCC column are used for either
securing method.
Weld Down Method
for welding a MCC column or shipping block to a
foundation.
Bolt Down Method
The two mounting channels allow up to four steel M12 bolts (minimum
Property Class 8.8) for each MCC column. We recommend that these bolts be
pre-located and embedded in the foundation before installing each MCC
column. See
through
for mounting bolt locations.
