The
branch
circuit
panel
for
the
computer
should
be
in
a
convenient,
well-lighted
area
of
the
computer
room.
Protect
the
individual
branch
circuits
on
the
panel
with
circuit
breakers
properly
rated
according
to
the
manufacturer's
specifications
and
applicable
codes.
Label
each
circuit
breaker
to
identify
the
branch
circuit
it
controls.
The
power
requirements
for
I/O
equipment
are

The
grounding
wire
of
the
branch
circuit
must
have
insulation
and
be
equal
in
size
to
the
neutral
and
phase
conductors.
Terminate
branch
circuits
as
close
as
possible
to
the
unit
they
supply-within
3
meters
(10 feet).
Run
branch
circuits
in
either
rigid
or
nonrigid
metallic
conduit
(or
in
compliance
with
local
or
national
standards).
The
conduit
system
should
be
continuous,
uninterrupted,
and
connected
to
the
building
or
transformer
ground;
see
Figure
I-Ion
page
1-9.
