Two 120
volt
circuits
are
available. One
circuit
across
"MP'
and "M2"
and another
circuit
across
'1M2"
and
"M3".
The load
on
each
i20volt
circuit
should not be
more
than
1/2
th~Sl!pacity
of
thepiant.
One 240 volt
circuit
is
available.
This
circuit
is
across
"Ml"
and "M3

•
"M2"is
,not

circuit.
If only
240yolt
current
is
used,
the

of
the
plant
may
be

'
Both 120 volt
current
and 240 volt
current
may
beused
at
the
same
time.
However,
the
total
of
either
120 volt load
plus
1/2
the
240
volt
load
should not exceed
1/2
the
capacity
of
the
plant.

only 1000

,To
