Power infeeds
The recommended electrical system for the UPLIFT
Power and Data Rail is the Byrne 8-Trac System. How-
ever, we have also designed the Power and Data Rail
to accept the Dekko 8-Wire System. This can help
prevent any delays if one of those two suppliers is ex
-
periencing long lead times.
The first type of power infeeds for the UPLIFT Pow
-
er and Data Rail is the Plug-in infeed (see fig.1) which
plugs into either a wall outlet or a floor outlet and can
be installed by anyone. Plug-in feeds are supplied by
a single 20 amp circuit that typically supplies your of-
fice wall outlets.
The second type of power infeed is the Hardwire in-
feed (see fig.2). The hardwire infeed connections must
be made by a licensed electrician.
The Power infeed accommodates up to four 20 amp circuits and consists of four line conductors,
two neutrals, and two grounds. Per National Electrical Code (NEC) requirements, up to 13 duplex
receptacles may be used per circuit, with a total of 52 available receptacles if all four circuits are
used. The line conductors are 12 AWG, and share a 12 AWG ground and a 10 AWG neutral conduc-
tor. The fourth circuit is isolated and dedicated and is serviced by its own line, neutral, and isolated
ground conductors. The Byrne 8-Trac System can be wired in both single and three-phase config
-
urations, 240/120V, 208/120V respectively (see Byrne 8-Trac wiring diagram below).
This power rail system utilizes (4) circuits; (3) for general purpose that share a common neutral and
ground, and (1) circuit that has a dedicated neutral and ground. This dedicated circuit is sometimes
used as the “computer” circuit since it does not share a neutral conductor, thereby reducing the
chance for electrical noise originating from other loads that may be plugged in. But many users plug
their computers into any of the 4 circuits without issues. Byrne duplex receptacles are marked as 1, 2,
3, and 4. Receptacles marked 1, 2, and 3 connect to the three general purpose circuits and the recep-
tacle marked 4 connects to the dedicated circuit. IF you optionally choose to only plug computers
into the dedicated circuit you may need to use additional power infeeds and an electrical designer
can help with this - as a general rule, you can assume 250W (2.08A) for each computer receptacle
and 180W (1.5A) for each general purpose receptacle when calculating for each 20A circuit.
