Joining and Splicing New
MCCs
A main horizontal bus splice kit must be installed between shipping blocks of
new MCCs to connect the main horizontal bus. In addition, the neutral bus
splice kit (if required) and the ground bus splice kit must be installed between
shipping blocks. Refer to CENTERLINE 2100 Motor Control Centers Joining
and Splicing Vertical Sections Instructions, publication

Joining and Splicing
Existing MCCs
A main horizontal bus, a neutral bus (if required), and a ground bus splice kit
must be installed when adding to existing CENTERLINE MCCs. When adding
to existing MCCs, you must identify the series of the MCC that you will be
adding to. If the existing MCC is series A or B, you must consult MCC technical
support at 1.440.646.5800 and follow the prompts to Allen-Bradley>Low
Voltage Motor Control Centers>Post Shipment Support for joining and splicing
procedures. When the existing MCC is series C or later, refer to
CENTERLINE 2100 Motor Control Centers Joining and Splicing Vertical
Sections Instructions, publication
Be sure to also connect DeviceNet cables and other control cables as required.
