Support Bracket
Additional Notes
If the MCC installation has the plenum exhausting to the left of the
lineup, then a plenum support (supplied with the order) maybe required.
If there are other cabinets to the left of the 800 Amp 1512A, like in Figure
B.18,
Figure B.18 – 800 Amp 1512A with another Arc Shield Cabinet
then the support is not required. But if there are no supporting cabinets to
the left of the 800 Amp 1512A, then the bracket must be used to support
the extension like in Figure B.19. With the bracket, four screws and
silicone caulking are supplied to secure and seal all holes to prevent exhaust
gases from escaping in the even of an arc fault.
