General Information Chapter 1
Each plug-in and frame mounted unit also has an identification label. The unit
label is on the interior of the bottom plate of plug-in units or on the interior
right-hand side plate of the frame mounted units. The unit label for each plug-in
or frame mounted unit includes:
• catalog number/serial number.
• series letter of the unit.
• voltage rating.
• unit location.
• UL and cUL certification marking.
• device type and size.
Figure 2 - Unit Label
The catalog number or serial number and series letter are required to properly
identify the equipment to sales or factory personnel.
MCC Sequence Numbering CENTERLINE MCCs are designed so functionality is not affected by the
section installation order, for example, vertical section-numbering sequence
order.
All MCC sections carry a serial plate that identifies vertical section sequence
numbering. For example, MCC section 1 of 1, 1 of 5, and so on.
