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 than 6.7 ft (2042.16 mm) a unit operating handle
extender should be added (catalog number 2100H-NE1).
