Specification Information
Morrison 2 +2 Raceway is a
four-circuit, eight-wire modular
power distribution system, for use in
Morrison panels and Network desk
supports.2+2Raceway
components distribute two 20-amp
convenience circuits (A and B), with
neutral and ground, and two
protected 20-amp circuits (X and Y)
with separate neutral and ground.

Application Notes
Power infeeds connect building
power supply to a cluster of
interconnected power rails. Desk
support infeed snaps into the end of
any desk power rail, and includes 6
foot liquid-tight conduit and pigtail
for connection to floor or wall
electrical box. Panel/desk connector
transmits power between the end of
a desk support rail and any panel
base power rail outlet position.
Hardwire infeed, used in all New
York City installations, includes
junction box that mounts to the
inside of a desk support corner leg.
Electrical contractor supplies
conduit from building power supply
to box and trims power connector to
length. Hardwire kit includes
painted finish cover panel.
Duplex outlets are preconfigured to
access one of the four circuits, A, B,
X, Y, and snap into any standard
outlet location (12 from either end
of desk). Duplexes on circuits X and
Y may be specified with orange face
or black face with orange triangle to
signify protected circuits for
electronic equipment; all other
duplexes are black.
Power connectors transmit power
between adjacent powered desks.
Crossover transmits power
‘‘diagonally’’ between non-adjacent
desks in a cluster of 3 or 4 desk
supports.
Jumpers connect rails on either side
of a desk end panel or desk support
without outlets.
