Frustrated by your local energy codes?
Are stringent energy codes impacting the way you highlight, promote and sell your merchandise? With energy
codes throughout North America establishing power limits for commercial and retail lighting environments, the
ability to apply trac lighting effectively is becoming increasingly difficult. Expressed in watts-per-square-foot,
these codes mandate total power consumption of installed lighting fixtures for a given space. Because of its
inherent flexibility, line-voltage trac lighting is typically assigned an arbitrary multiplier for purposes of energy
calculations. Depending on the specific code, these multipliers can range from 30 to 70 watts per foot of trac,
regardless of the actual power consumed by the specified fixtures. Therefore, even though a trac lighting
installation may employ energy efficient fixtures, the watts-per-linear-foot power consumption formula still
applies, effectively penalizing an otherwise energy-conscious design.
Fortunately, there is a simple solution to this dilemma. By specifying a Juno current limiting solution with
your trac lighting, energy codes permit the current limiter rating to be substituted for the linear footage
formula. This means that trac installations can be designed using ultra-efficient fixtures, and effortlessly
achieve code compliance.
The Solutions
Juno Lighting Group can help you meet the challenge of energy code compliance with
either a Current Limiting Subpanel or Current Limiting Trac Feeds. The Subpanel solution
installs between the branch circuit breaker and the trac lighting equipment and provides
the lowest installed-cost solution. The Current Limiting Trac Feeds are intended to be
installed at every trac feed location in place of a standard non-limiting feed, making it
perfect for either new construction or upgrading existing circuits in a remodel or retrofit
application. By incorporating either current limiting solution into company-wide trac
lighting specifications, multi-facility organizations can be assured of lighting code
compliance regardless of location. And no matter which system is best suited to a given
application — subpanel or trac feed — Juno is your one-stop supplier for both solutions.
How the Devices Work
Both systems utilize supplementary current limiting circuit breakers, designed to limit
available wattage based on the actual lighting design criteria, thereby avoiding the
“watts-per-linear-foot penalty” imposed by energy codes. Trac lighting density and
performance can be optimized, and configuration flexibility can be retained, without
exceeding code-mandated power utilization limits.
Optimize Your Energy Usage
To optimize your energy usage and to maximize operating cost savings, combining energy
efficient LED, high-performance ceramic metal halide (CMH) and economical compact
fluorescent trac fixtures with either current limiting solution can reduce calculated energy
use by as much as 75% or more versus standard halogen fixtures. This enables you to
provide the lighting you need to effectively highlight merchandise and increase sales.

Case Study
Background
A leading specialty retailer with more than 1,000
locations nationwide planned to renovate each location.
The rebranding efforts of the retail store locations
included extensive trac lighting, providing the retailer
with the flexibility to move, replace and redesign
merchandising displays.
With their rebranding efforts, the retailer recognized
that greater efficiencies could be realized, not only in
energy, but in overall maintenance costs by using
Juno’s energy efficient, high performance LED trac
fixtures. But this energy savings wasn’t enough when
the new energy codes were enforced.
Challenge
With new energy codes throughout North America placing
a mandatory limit on lighting density, trac lighting had an
additional burden: an automatic VA (wattage) calculation
per linear foot of trac. ASHRAE 90.1, the basis for many
municipal energy codes around the country, assigns
30-watts per linear foot of trac. California’s Title 24 code
assigns 45-watts and other more stringent codes may
assign up to 70-watts per linear foot.
Using California Title 24’s 45-watts per linear foot
calculation, the retailer’s lighting layout had the calculated
potential of using over 35,000 watts in a single store
according to the energy code. This was an enormous
exaggeration above the actual planned wattage of 7000
watts per store and 8.75-watts per linear foot of trac.
With stores projected to open in just a few weeks,
redesigning the stores again and eliminating a large
portion of trac lighting was not an option.
Solution
To solve this problem, the retailer called on
the expertise of their local Juno Lighting
Group National Account Sales Manager.
Working around the clock to meet a nearly
impossible build schedule, and working
closely with the California Energy
Commission to obtain early acceptance and
to avoid delaying any store openings, the
solution was a sub-branch current limiting
panel. This panel would limit the amount of
wattage used on each trac, consequently
eliminating the penalty for the calculated
potential maximum load/unused wattage.
The Juno Current Limiting Subpanel
reduced the retailer’s calculated potential/
unused wattage by over 75%. In fact, the
retailer selected their current limiters to total
8000 watts, leaving them with additional
flexibility for expansion while still easily
complying with the local energy codes.

Energy Code Calculations
Illustrated below is an example of what current limiting means
for trac lighting relative to today’s energy codes. The standard
layout without a current limiting solution consists of 100’ of single
circuit trac (4 circuits x 25’ each) with 32 LED trac fixtures, each
consuming 24W maximum, for a total connected load of 768W.
Per the Title 24 energy code, the wattage calculation would be
a much greater 4500W.
The scenario with the Trac-Master Current Limiting Subpanel uses the original 100’ of
single circuit trac, broken down into four 25’ runs, with each monitored by a 2-Amp
current limiting supplementary protector that is closely matched to the actual
connected load plus a small buffer. This results in the minimum calculated watts per
the energy codes, making the wattage calculation independent of trac length.
In a real application, there would be many more trac lighting circuits, resulting in
an even greater calculated wattage reduction.
Calculations Example
Without Current Limiting
Track length determines wattage calculation
Actual Connected Load = 24W x 32 Fixtures = 768W
100 ft of trac = 4500W*

Current Limiting Subpanels
The Juno Current Limiting Subpanel
permits you to take full advantage of
any line voltage trac lighting without
being penalized by watts-per-linear-foot
energy code calculations. The subpanel
is typically installed out-of-sight in an
electrical control room, providing a
centralized location for installation wiring
and breaker access in the event of a
circuit overload. The Current Limiting
Subpanel installs between the branch
circuit breaker and the trac lighting
equipment. This limits the amount of
power that is available to operate the
trac circuit to only the wattage needed
per the lighting plan. Installation labor
is minimized since multiple trac runs
can be fed from a single current limiting
circuit breaker.
The subpanel is offered in any
configuration from 1 thru 42 circuits
and is available in either surface or
flush mount versions. Current limiting
is provided by supplementary current
limiting breakers that are selected
at the time of order based on the
actual lighting loads specified.
Breakers are rated 120/277V and are
available in 0.5A, 1A, 2A, 3A, 4A, 5A,
6A, 7A, 8A, 10A, 13A and 15A current
ratings. Note that Juno recommends
that breakers be loaded to maximum
of 80% of rating to avoid nuisance
tripping. All Current Limiting
Subpanels are factory pre-assembled
and customized for your specific
application . . . no programming is
required. Complimentary factory
assistance is available to guide you
through the simple specification process.
