e. The type of wiring system, such as rigid conduit, electrical metallic tubing,
nonmetallic sheathed cable, etc., and the location of each type proposed for use.
f. The types of conductors, such as rubber insulated, varnished cambric, insulated lead
covered, etc., and the location of each type proposed for use.
g. The proposed design allowance for voltage drop and the designed lighting intensities.
h. A description of the proposed types of lighting fixtures.
i. The short circuit currents for all protective devices and switchgear. Select and
indicate the set points and operating ranges of all protective devices and ensure that
the electrical system is properly coordinated.
j. The type and arrangement of telephone, signal, security and fire alarm systems.  Provide an equipment ground wire for equipment circuits of 225 amperes and less.
