ELECTRICAL SYSTEMS
4.8.1
A. Interior distribution systems.
(1) Electrical characteristics (phase, voltage, and number of conductors).
(2) Breakdown, by category, of the estimated connected loads, demand
factors and demand loads for each category, total demand load, diversity factor, and
total diversified demand load. Load categories shall include the following:
(a) Lighting load.
(b) Convenience outlet load.
(c) Mechanical equipment load, such as heating, air conditioning, etc.
(d) Special operating equipment loads, such as compressors,
generators, pumps and power receptacles being provided to serve special equipment.
(e) User equipment loads.
(f) Miscellaneous/other loads.
(3) Type of wiring system, such as rigid conduit, electrical metallic
tubing, nonmetallic sheathed cable, etc., and where proposed to use. (CURRENT
CRITERIA PROHIBITS EMBEDDING ALUMINUM CONDUIT IN CONCRETE.
CURRENT PROJECTS SHOULD BE REVIEWED TO MAKE SURE THAT CONDUIT,
PIPE, BARS, ANCHORS, FLASHING, OR OTHER ALUMINUM PARTS ARE NOT
EMBEDDED IN CONCRETE.)
(4) Type of conductor and insulation material, such as CU THW, AL
XHHW, etc., and where proposed to use.
(5) A statement describing proposed standards of design, such as voltage
drop, lighting intensities, type of light sources, and a statement regarding the use of
selective switching or other energy conserving features.
(6) Provide short circuit calculations.
