Specification Information
Morrison 3 +3 Raceway is a
six-circuit, ten-wire modular power
distribution system, for use in
Morrison panels and Network desk
supports.3+3Raceway
components distribute three 20-amp
convenience circuits (A, B, C), with
neutral and ground, and three
protected 20-amp circuits (X, Y, Z)
with separate neutral and ground.
A, B, X, Y outlets are identical to
eight wire, 2+2 components.
Duplex outlet circuits are
designated by white letters on black
background.

Application Notes
Power rails are the primary power
distribution component of the
Morrison3+3Raceway. Each rail
provides outlet mounting positions
on both sides, and receptacles for
branching power connectors at each
end. Center supports permit lay-in
cabling from either side of the
raceway. Rail for 24 wide panel
accepts one duplex outlet or power
infeed on either side. Rails for 30
and wider panels accept two outlets
each side, 12 from either end of the
panel. Power rail for Vertical
Raceway panel accepts up to four
duplex outlets each side, two above
and two below standard worksurface
height.
Power connectors transmit power
between adjacent powered panels.
Specify straight power connector for
straight connections, and post power
connector for L, T or X post
connections.
Duplex outlets are preconfigured to
access one of the six circuits, A, B,
C, X, Y, Z, and snap into any
standard outlet location (12 from
either end of panel). Duplexes on
circuits X, Y, and Z may be
specified with an orange face, or
black face with orange triangle to
signify protected circuits for
electronic equipment; all other
duplexes are black.
If separation of cabling and
electrical wires is required, a data
shield can be attached below the
power rail. Data shields are field
installed.
