You are preparing a preliminary
site plan for a new public works
maintenance facility. On this site
plan, the electrical design
engineer requires information, such
as the location, identification,
and class of existing distribution
poles; the location,
identification, and capacity of
existing transformers; and the
size, type, and voltage of existing
overhead and underground
conductors. In what source(s)
should you look first to find this
information?
1.
The station’s electrical
distribution drawings or plans
2.
The surveyor’s field books
3.
The station master plan
4.
The electrical site plans for
all surrounding buildings or
facilities
2-32.
Electrical manholes are identified
on electrical utility drawings by
1.
number and type only
2.
symbol, dimensions, and
elevation
3.
identification number,
location, type, dimensions, and
