Hang it from the Bus

Perhaps the most successful product Litelab has
introduced in the last 20 years, BusRun has been
adopted worldwide thanks to the following features:
■■
■■
■■
Electrical code variants for bus combined with its far
greater current capacity greatly reduce installation
cost with no compromise on your design.
BusRun’s structural integrity allows for unique
features when suspended or recessed.
Litelab innovations have allowed BusRun to
do double duty, including HVAC integration,
supporting hanging objects, or becoming part
of a ceiling structure allowing the designer much
greater flexibility at much lower cost.
The next time you have a need for a linear power
source let Litelab’s application engineers assist in
allowing your design to reach its full potential – take
the Bus and leave the driving to us.

Hanging
Because BusRun Busway is structurally selfsupporting,there’s no need for extra stabilizing
elements—BusRun can hang independently from
mounting points up to 10 feet apart. Not so with
structurally flimsy track. Track requires more
frequently spaced pendants and often ‘long’ runs are
mounted to a sturdier element for support. Couple
this with the number of extra costly feeds required
for track by electrical codes. With BusRun you have
a lighting system that is both clean and beautiful
compared to standard track.

Surface
Because of its virtually seamless design, lengths
of Surface-Mount BusRun meet neatly end-to-end,
with all necessary hardware concealed internally.
The long runs allowed for BusRun Busway by
electrical codes result in fewer feeds for less
clutter and significant savings. BusRun fitters
recess completely into the BusRun Busway, rather
than hanging below it, to further minimize visual
distraction above the connected load.

Recessed
Recessed BusRun fully integrates with the structural
environment and blends seamlessly into the ceiling.
Unlike recessed track housings, which install
separately from the track, recessed BusRun has
integrated flanges. And, because a single feed can
power up to 260 feet of BusRun, it’s easier to provide
fewer feed connections than would be necessary
for track.

A snap-in cover plate attaches to the
mounting channel - providing a finished
appearance for the sprinkler head.
Air flows around the BusRun
extrusion and through a knockout
in the mounting channel and into
an HVAC duct (installed by others).
Sprinkler Heads.. No Problem!
LiteLab specializes in recessed bus systems that
multitask, performing as part of an air handling
system, providing extra circuits for emergency
power, smoke alarms and security systems,
and incorporating some of the most advanced
technologies, like occupancy sensors and fiber
optic communications. We also provide systems
with interrupted power and extrusion penetrations
for sprinklers, and other requirements.

Mounting brackets are angled 90°

Miter Cut BusRun
BusRun has the unique weight bearing capacity
of accepting a load of up to 100lbs/45kg between
hanging points—ßimagine the possibilities:
monitors, merchandise, works of art… the
potential is almost endless. BusRun provides
flexible solutions to give your project the added
advantage.
Does your installation require unique shapes?
BusRun can be cut and welded into a variety of
geometries, and is capable of accommodating
both horizontal and vertical orientations. Its
unique structural strength also lets it be supported in unique ways—allowing it to become
an integral aspect of your unique architectural
aesthetic.

Recessed in Wood Ceilings...
Busrun Busway can also function as the main
runner of support in most panel ceiling systems.
Its unique structural strength will support
ceiling loads, and it can tie into most paneled
ceiling support grids. Just another feature that
allows BusRun to multitask for you.
Busrun Busway provides many unique mounting
techniques that allow it to be incorporated into
wood ceiling systems for a aesthetically pleasing solution. Consult our application engineers.

DESIGN IDEAS
Emergency circuits (highlighted
in yellow) can be integrated within
runs of BusRun and daisy-chained
reducing the numbers of feeds
required.
Primary circuits are daisy-chained
and wired independently of the
emergency circuits.
Integrated Emergency Circuits...
It is no longer necessary for egress systems to
be unsightly. With BusRun, emergency circuits
can be incorporated directly into the busway
system with matching fixtures and tamper
resistant fitters.
All connections can be made within
the BusRun extrusion and covered
with a splice plate. This eliminates
the need for a separate junction
box or long built-in wire whips.
