INSPECTION
AFTER
LOAD
CABLE
INSTALLATION
PRIOR
TO
INSTALLATION
Before
any
installation
work
is
performed
,
study
all
drawings
furnished
by
the
General
Electric
Company
for
the
particular
installation
.
These
include
arrangement
drawings
(
front
,
end
and
plan
view
)
,
connection
diagrams
and
schedule
of
equip
-
ment
.
Any
material
external
to
the
equipment
which
may
be
required
to
meet
any
local
codes
(
railings
,
etc
.
)
is
not
furnished
.
To
prevent
heating
,
there
should
be
no
closed
loop
of
steel
around
a
single
conductor
or
group
of
conductors
which
does
not
include
all
the
conductors
(
including
the
neutral
)
of
the
circuit
.
If
the
conductors
must
pass
through
separate
holes
in
a
piece
of
steel
,
slots
should
be
cut
between
the
holes
.
Do
not
allow
cables
carrying
heavy
current
to
come
near
instruments
or
meters
as
this
may
affect
their
accuracy
.
Use
the
minimum
amount
of
cable
necessary
to
accomplish
the
connections
.
The
increased
resis
-
tance
of
longer
cables
generates
unnecessary
heat
.
Load
cable
lashing
should
be
checked
bi
-
monthly
.
INSTALLATION
PROCEDURES
FOR
LOAD
CABLE
WITH
SHORT
CIRCUIT
PROTECTION
Locate
the
load
cable
braces
which
can
be
found
every
18
"
on
the
back
of
the
switchboard
.
Run
and
bend
the
load
cable
in
the
most
convenient
manner
,
making
sure
that
the
load
cable
is
up
against
the
load
cable
brace
closest
to
the
component
’
s
load
terminals
(
see
Figure
7
E
)
and
to
every
load
cable
brace
above
or
below
,
depending
if
the
load
cable
will
exit
the
switchboard
on
top
or
bottom
(
see
Figure
7
F
)
.
After
running
the
load
cable
up
against
the
load
cable
braces
and
using
a
polyester
braided
rope
having
a
tensile
strength
of
2000
lbs
.
minimum
,
lash
the
load
cable
to
the
load
cable
brace
,
making
4
revolutions
around
the
cable
and
the
brace
.
Tie
a
knot
to
the
cable
brace
after
completion
of
the
last
revolution
.
All
revolutions
should
be
made
as
tight
as
possible
so
as
to
prevent
whipping
during
short
circuits
.
