require heat or flame, or any additional materials such as
coverings or adhesive. It shall be designed for use with inline
compression type connectors, or indoor, outdoor, direct-burial or
submerged locations.
e.
Where aluminum conductors are provided, use particular care in
making up joints and terminations. Remove surface oxides by
cleaning with a wire brush or emery cloth. Provide joint compound
on conductors, and UL listed solid aluminum connectors for
connecting aluminum to aluminum. When connecting aluminum to
copper, provide connectors specifically designed for connecting
aluminum to copper.

**************************************************************************
a.
Use particular care in making up joints and terminations. Remove
surface oxides by cleaning with a wire brush or emery cloth.
Apply joint compound to conductors, and use UL-listed solid
aluminum connectors for connecting aluminum conductors. When
connecting aluminum to copper conductors, use connectors
specifically designed for this purpose.
b.
Terminate aluminum conductors to copper bus either by: (1) in
line splicing a copper pigtail to the aluminum conductor (copper
pigtail shall have a ampacity at least that of the aluminum
conductor); or (2) using a circumferential compression type,
aluminum bodied terminal lug UL listed for AL/CU and steel
Belleville spring washers, flat washers, bolts, and nuts.
Belleville spring washers shall be cadmium-plated hardened steel.
Install the Belleville spring washers with the crown up toward the
nut or bolt head, with the concave side of the Belleville bearing
on a heavy-duty, wide series flat washer of larger diameter than
the Belleville. Tighten nuts sufficient to flatten Belleville and
leave in that position. Lubricate hardware with joint compound
prior to making connection. Wire brush and apply joint compound
to conductor prior to inserting in lug.
c.
Terminate aluminum conductors to aluminum bus by using
all-aluminum nuts, bolts, washers, and lugs. Wire brush and apply
joint compound to conductor prior to inserting in lug. Lubricate
hardware with joint compound prior to making connection; if bus
contact surface is unplated, scratch-brush and coat with joint
compound (without grit).

Medium Voltage Cable Terminations
**************************************************************************
NOTE: Use this paragraph for LANTNAVFACENGCOM

**************************************************************************
Provide terminating devices and materials to protect medium voltage cable
terminations from accidental contact, deterioration of coverings, and
moisture. Make terminations by using materials and methods specified
