VR For vertical raceway
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.
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 panel). 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.
Power infeeds connect building
power supply to a cluster of
interconnected power rails. Panel
base infeed snaps into any outlet
position in rail, 12 from either side
of panel, and includes 6 foot
liquid-tight conduit and pigtail for
connection to floor or wall electrical
box. MR3-ERPI Panel Base Infeed
rotates to provide either a left- or
right-hand power entry.
Ceiling infeeds include
12-6pigtail for connection into
panel base through Morrison
vertical raceway and ceiling infeed
panel, or through standard power
pole (supplied by others) adjacent to
Morrison panel with power rail.
Hardwire infeed, used in all New
York City installations, includes
junction box that mounts within
non-powered panel base (any width
24 or greater). Electrical contractor
supplies conduit from building
power supply to panel, punches
infeed hole in raceway cover, and
trims power connectors to length.
MR3-EPNY2 includes two power
connectors to power panels on both
sides of infeed panel; MR3-EPNY1
includes only one power connector.
Template is included to modify
standard N-type raceway cover
(without outlet openings).
Power infeed for Panel base for San
Francisco installations have a
liquid-tight sleeve over a metallic
flexible conduit.
