DIFFERENCE BETWEEN MODELS.
a.
The major difference between the DISE and PDISE systems are:
(1) The DISE models (M40, M60, M1OO and M200) use thermal-magnetic
circuit breakers while the PDISE models (M40 A/P, M60 A/P, M1OO A/P and M200
A/P) use hydraulic-magnetic circuit breakers.
(2) The DISE models use one
length of wire for each model inside the enclosure assembly while the PDISE
models use different lengths of wire due to bus bar location and type of
circuit breaker.
(3) The DISE models have ground fault circuit interruption
while the PDISE models do not use the ground fault circuit interruption
circuit breaker.
(4)
The inside covers for DISE models are designed
differently from PDISE models due to size of circuit breakers.
b.
Three-Phase DISE and PDISE Equipment.
The M40, M40A/P, M1OO,
M1OOA/P, M200, and M200 A/P systems require a 3-phase electrical power source
rated at 208V ac, 50/60 Hz for input power.
These systems will provide 3-phase
(208 V ac, 50/60 Hz) or single-phase (120 V ac, 50/60 Hz) electrical power,
depending on which output receptacles are used.
These three systems will
interconnect to provide a 3-phase plus single-phase electrical network of up to
72 kW total capacity.
c.
Single-Phase DISE and PDISE Equipment.
The M60 and M60 A/P systems
requires a single-phase electrical power source rated at 120 V ac, 50/60 Hz,
for input power.
This system will provide only single-phase (120 V ac,
50/60 Hz) electrical power at the output receptacles.
d.
Electrical Utility Assembly.
The M46 system connects to the M60
system outputs or to the single-phase outputs of the 3-phase systems (M40, M40
A/P, M1OO, M1OO A/P, M200 and M200 A/P).
The M46 system consists of various
electrical cables, lights for illumination, and standard household type duplex
receptacles for plugging in electrical loads not to exceed the rating of the
circuit breaker.
e.
Common Features.
(1) DISE and PDISE Feeder/Distribution Centers.
(a) Each center uses a 4-foot (1.2 m) pigtail cable to connect
to the generator.
(b) Each center is equipped with a master circuit breaker rated
at the maximum permissible load.
(c) Each center is equipped with phase indicator lights which
indicate the presence of input power.
(d) Each center
is equipped with branch circuits that are
individually protected with circuit breakers.
(2) DISE and PDISE Cables.
(a) Cables are equipped with at least one phase wire, one
neutral wire, and one ground wire.
