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