 1) A summary of the criteria upon which the electrical design
will be based. Include the proposed pertinent standards of design, such as
voltage regulation, lighting intensities and type of lighting fixtures.
2) General description of the proposed electrical systems
including their advantages and suitability for the proposed project. Include
discussions on:
(a)
Primary Distribution (Coordinate with Utility Data
Sheets):

demand load and annual consumption when applying proper demand and load
factors.
(4)
Basis for selection of secondary voltage.
(5)
Type of conductors, such as copper or aluminum.
(6)
Type of conduit or duct, if used.
(7) A statement describing pertinent standards of
design, such as voltage drop, physical characteristics of overhead or
underground circuits, clearances, etc.
