withstand [120] [480] hours of exposure to the salt spray test specified in
ASTM B 117 without loss of paint or release of adhesion of the paint primer
coat to the metal surface in excess of 1.6 mm 1/16 inch from the test mark.
The described test mark and test evaluation shall be in accordance with
ASTM D 1654 with a rating of not less than 7 in accordance with TABLE 1,
(procedure A). Cut edges or otherwise damaged surfaces of hot-dip
galvanized sheet steel or mill galvanized sheet steel shall be coated with
a zinc rich paint conforming to the manufacturer's standard.
2.4.3
Finishing
Painting required for surfaces not otherwise specified and finish painting
of items only primed at the factory shall be as specified in Section 09900
PAINTS AND COATINGS.

CONDUCTORS, CONNECTORS, AND SPLICES
**************************************************************************
NOTE: Justify the selection of copper or aluminum,
based upon an analysis using life, environmental,
and cost factors.
**************************************************************************
2.5.1
Aluminum-Composition Conductors
[All-aluminum-conductors, AAC, shall be alloy 1350-H19 and comply with ASTM
B 230/B 230M and ASTM B 231/B 231M.] [All-aluminum-alloy-conductors, AAAC,
shall be alloy 6201-T81 and comply with ASTM B 398/B 398M and ASTM B 399/B
399M.] [Aluminum-conductor-steel-reinforced, ACSR, shall comply with ASTM B
232/B 232M.]
2.5.2
Copper Conductors
Hard-drawn-copper conductors shall comply with ASTM B 1 and ASTM B 8 as
appropriate for the conductor size.
2.5.3
Connectors and Splices
Connectors and splices shall be of copper alloys for copper conductors,
aluminum alloys for aluminum-composition conductors, and a type designed to
minimize galvanic corrosion for copper to aluminum-composition conductors.
Aluminum-composition, aluminum-composition to copper, and copper-to-copper
shall comply with UL 486A-486B.
2.6
MEDIUM-VOLTAGE LINES
2.6.1
Bare Medium-Voltage Lines
Bare medium-voltage line conductors shall be [all-aluminum-conductor, AAC;]
[all-aluminum-alloy-conductor, AAAC;] [aluminum-conductor-steel-reinforced,
ACSR;] [hard-drawn-copper, CU]. Conductor types shall not be mixed on any
project, unless specifically indicated. Conductors larger than No. 2 AWG
shall be stranded.
2.6.2
Insulated Medium-Voltage Lines
