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

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