Wireways
Each MCC has horizontal and vertical wireways for continuous dedicated wire and cable location.
Horizontal Wireways
Horizontal wireways are located at the top and bottom of each
MCC section. Horizontal wireways extend the full width and
depth of the MCC. The top and bottom are horizontal wireways
6 in. (152.4 mm) high. Complete wireway access from front to
rear is available for back-to-back configured MCC sections.
Horizontal wireways have removable front covers that are held
in place by captive screws. Openings in the side plate of the
section allow access to the top and bottom horizontal wireways
between joined sections. Plates are provided to cover these
openings for sections located at the end of a MCC lineup.
Horizontal wireways are isolated from the power bus. Horizontal
wireways for incoming line sections are reduced depth to
maintain isolation from the incoming line area.
Vertical Wireway
The vertical wireway is located on the right side of each section and extends 78 in. (1981 mm), between the top and the
bottom horizontal wireway. The vertical wireway is approximately 7 in. (178 mm) deep. The standard vertical wireway is
4.37 in. (111 mm) wide. Vertical wireways are also available in 9.37 in. (238 mm) widths.
The vertical wireway is isolated from power bus and is independent of unit space. Vertical wireways are not present in
sections with frame-mount units.
Vertical wireways are covered with steel doors and held in place by at least three door latches.
Vertical wireway tie bars are available to help you keep your cable wireways organized.
Master Nameplate
The MCC master nameplate, when specified, measure 2.0 in. x 6.0 in. (50.8 mm x 152.4 mm) and is available with up to five
lines of engraving and is located on the top horizontal wireway cover.
