Installation Procedures
Location Planning
When planning the location for your CENTERLINE MCC, consider the
following:
• Conduits
• Busways
• Overall height of installation area
• Alignment with other equipment
• Future needs
• Ambient temperature
The area must be level and the environment must be compatible with
the NEMA enclosure rating of the equipment
Documentation packages shipped with assembled MCCs include an
MCC elevation drawing and an MCC floor plan layout.
Height Considerations
If the MCC is equipped with optional external mounting channels or is
mounted on a pad, the height from the floor to the center of the top
handles must be checked for compliance with NFPA 70 National
Electrical Code (NEC) Article 404.8 and UL Standard 845. If the
distance from the floor to the center of the highest handle is greater
then 6.7 ft (2042.16 mm) a unit operating handle extender should be
added (catalog number 2100H-NE1).
