REMOTE
START-STOP
SWITCH
(Optional)
For
remote
control
starting
and

use
three
wires
to
connect
the
remote
switch
(SPOT,
momen¬
tary
contact,
center-off
type)
to
the
terminal
block
marked
B+,
1,

in
the
set

Use
#18
gauge

for
runs
up
to
250
feet
(76

and
larger
wire
for
longer
runs.

LOAD
WIRE
CONNECTIONS
The
generating
set
nameplate
shows
the
electrical
output
rating
of
the
set
in
watts,
volts
and
hertz.
The
portable
models
are
prewired
and
have
a
receptacle
box
with
two
duplex
120-volt
(15-ampere),
grounding
receptacles
and
two
240-volt
(20-ampere),
twist-lock
receptacles.
For
the
other
generating
sets,
the
wiring
diagram
shows
the
electrical
circuits
and
necessary
connections
for
the
available
output
voltage.
A
qualified
serviceman
orelectrician
should
make
the
installation
and
the
installation
should
be
inspected
and
approved
to
meet
all
applicable
code
re¬
quirements.
The
AC
output
box
has
provisions
to
accommodate
load
wires.
Use
flexible
conduit
and
sufficiently
large
stranded
load
wires
near
the
set
to
absorb
vibration.
Strip
the
insulation
from
the
wire
ends
as
necessary
for
clean
connections.
Connect
each
load
wire
to
the
proper
generator
output
lead
inside
the
AC
output
box.
Insulate
bare
ends
of
ungrounded
wires.
Install
a
fused
main
switch
(or
circuit
breaker)
between
the
generating
set
and
the
load.

120

or,
240

wire
(Figure

Use
the
connection
for
two-wire
service
when
one
load
exceeds
one-half
the
rated
capacity.
Balance
the
load
when
connecting
for
three-wire
service.
Current
for
any
one
output
lead
must
not
exceed
nameplate
rating.
Serious
overloading
can
damage
the
generator
windings.
When
two
or
more
single-phasecircuitsareavailable,
divide
the
load
equally
between
them.
Three-Phase,
Four-Wire,
Wye
Connected
Generators:
A
three-phase,
four-wire
generating
set
produces
single-phase
current
of
the
lower
nameplate
voltage
and
three-phase
current
of
the
higher
nameplate
voltage
(Figure
10).
For
single¬
phase
current,
connect
the
neutral
(white)
load
wire
to
the
grounded
terminal.
Connect
the
“hot”
(black)
load
wire
to
any
one
of
the
other
three

Three

circuits
are
available,
with
not
more
than
one-
third
the

of
the
generating
set
from
any
one
circuit.
For
three-phase
current,
connect
separate
load
wires
to
eachofthegeneratorterminals

Single-phase
current
of
the
higher
nameplate
voltage
is
obtained
between
any
two
three-
