Specification Information<br />
Morrison 3 +3 Raceway is a<br />
four-circuit, eight-wire modular<br />
power 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 />

Application Notes<br />
Power infeeds connect building<br />
power supply to a cluster of<br />
interconnected power rails. Panel<br />
base infeed snaps into any outlet<br />
position in rail, 12 from either side<br />
of panel, and includes 6 foot<br />
liquid-tight conduit and pigtail for<br />
connection to floor or wall electrical<br />
box. MR3-TRPI Panel Base Infeed<br />
rotates to provide either a left- or<br />
right-hand power entry.<br />
Ceiling infeeds include 12’-6<br />
pigtail for connection into panel<br />
base through Morrison vertical<br />
raceway and ceiling infeed panel, or<br />
through standard power pole<br />
(supplied by others) adjacent to<br />
Morrison panel with power rail.<br />
Hardwire infeed, used in all New<br />
York City installations, includes<br />
junction box that mounts within<br />
non-powered panel base (any width<br />
24 or greater). Electrical contractor<br />
supplies conduit from building<br />
power supply to panel, punches<br />
infeed hole in raceway cover, and<br />
trims power connectors to length.<br />
MR3-TPNY2 includes two power<br />
connectors to power panels on both<br />
sides of infeed panel; MR3-TPNY1<br />
includes only one power connector.<br />
Template is included to modify<br />
standard N-type raceway cover<br />
(without outlet openings).<br />
Power infeed for panel base for San<br />
Francisco installations have a<br />
liquid-tight sleeve over a metallic<br />
conduit.
