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 Chapter 4 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
See Figure 13 on page 35 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
page 31 through page 33 for mounting bolt locations.
