Dividends Horizon
3+1 Circuit Electrical
The Dividends Horizon 3+1 electrical system
is designed for areas where power usage is
The wire configuration of the 8-wire/4
circuit electrical system is (see chart):
for circuits #1, 2 and 3
for circuits #1, 2 and 3
yellow) for circuit 4
Circuits 1, 2 and 3 have shared neutral and
grounds for convenience power while circuit
4 has a separate ground and neutral for
designated/isolated power or to support
uninterrupted power supply (UPS).
Compatibility
All Dividends Horizon power systems
use components that appear similar.
However, components from the three
different power systems are not functionally,
fully interchangeable. 3+1 components
can be connected to 3+3 wire systems,
however only 3+1 will function.

3+1 Duplex Receptacles
Duplex receptacles used in 3+1
electrical systems are:
1(pattern number DE1DR1)
2 (pattern number DE1DR2)
3 (pattern number DE1DR3)
(pattern number DE1DR4)
Isolated duplex receptacle number 4
has an orange-colored triangle on black
background to identify an isolated duplex.
An optional orange-colored isolated
duplex is also available. It has the isolated
identifying triangle outlined in black.

3+1 Electrical System Technical
Specifications
The 3+1 electrical system consists of
four 20 amp, 120 volt, 60-Hertz circuits.
The circuits will accommodate 120 volt
single phase, 120/240 volt split phase and
120/208 volt three phase power. System
components are 20 amp capacity. The
National Electric Code (NEC) limits continuous
loads to 80% of capacity or 16 amps.
Wires
Typically, each circuit can power 8-10 duplex
convenience outlets with normal loads. In
heavier load situations, such as computer
systems, each circuit will power 3-5 duplex
outlets. If each workstation has two convenience
duplex outlets and one protected duplex, the
8-wire (4-circuit) system can supply a cluster
of 6 -10 workstations from each infeed.
Surge Suppressors
Dividends Horizon surge suppressors
(pattern number DE1SS) plug into any
terminal block position to provide surge
protection for all duplexes on that circuit.
Note: When connected, surge suppressors take
the place of a duplex receptacle resulting in the
elimination of one duplex position from the circuit.
Independent Neutral Electrical Systems
Dividends Horizon offers a 2+1 electrical system
with independent neutrals as a standard special.
It is our belief that independent neutrals are
an independent neutral electrical system, a
Dividends Horizon solution can be provided. For
further information, list pricing and schematic
drawings, contact Knoll Customer Service.
