Sequence Numbering
Each CENTERLINE 2500 MCC column nameplate identifies column sequence
numbering, for example, MCC column 1 of 1 or 1 of 5.
Figure 8 - Column Nameplates
Columns are numbered to match factory-supplied MCC elevation drawings.
Numbering each column helps installers and users easily identify MCC columns
and units. If there are questions about column numbering during field
installation, inspection, or operation, the following instructions can provide
guidance.
The most important criteria for additions of columns to existing MCCs is
matching the horizontal bus, enclosure type, and network capabilities for the
complete MCC line up. The voltage, current rating, short circuit withstand, and
IP rating for all columns must be consistent.
IMPORTANT CENTERLINE 2500 MCCs are designed so functionality is not affected by the
column numbering sequence. However, we recommend that columns be
installed in sequential order.
IMPORTANT Leftmost column must be installed in the proper location for the bus to splice.
(Both ends of double-front MCCs must be installed as ends for splicing.)
