necessary operating power. Hydraulically-controlled reclosers shall be
provided with tank drains and sampling valves. Surge arrester protection
shall be provided. [Reclosers shall be equipped with [ground fault
tripping] [and] [three-phase current metering] equipment.]
2.12
CAPACITORS
Capacitor equipment shall comply with IEEE Std 18 and shall be of the
three-phase, grounded-wye, outdoor type rated for continuous operation and
automatically switched. Equipment shall be suitable for mounting on a
single pole. Polychlorinated biphenyl and tetrachloroethylene
(perchloroethylene) shall not be used as the dielectric. Equipment shall
be rated for the system voltage. The indicated kvars shall be
automatically switched by [single-step [time switch] [voltage] [current]
[kilovar] control] [multiple-step [voltage] [kilovar] control providing the
indicated number of steps and switching the indicated kvar]. Necessary
transformers shall be provided for sensing circuit variations and for
low-voltage control. Oil-immersed switches shall be provided for automatic
switching of capacitors, and shall be electrically separate from ungrounded
capacitor enclosures and metal frames. Installations shall include one
primary fuse cutout and one surge arrester for each ungrounded phase
conductor. Fuse link ratings shall be in accordance with the
manufacturer's recommendations. Capacitor equipment, except for
low-voltage control and primary fuse cutouts, shall be subassembled and
coordinated by one manufacturer. Units, including metal pole-mounting
supports and hardware, shall be shipped in complete sections ready for
connection at the site. Low-voltage equipment shall be socket or cabinet
type, mounted on the pole approximately 1.2 m 4 feet above grade, shall be
connected with the necessary wiring in conduit to capacitor equipment, and
shall be provided with secondary arrester protection against switching
surges when recommended by the manufacturer.

FUSES AND SWITCHES, MEDIUM-VOLTAGE
**************************************************************************
NOTE: See TM 5-811-1 for guidance on the
application of fuses and switches.
A short-circuit study is required to specify
ratings. See TM 5-811-14 and UFGS-16475A
COORDINATED POWER SYSTEM PROTECTION.
**************************************************************************
2.13.1
Fuse Cutouts
Medium-voltage fuses and cutouts shall be of the [loadbreak] [nonloadbreak]
[enclosed] [open] type construction [rated [5.2] [7.8] [15] [27] [38] kV
and of the [normal] [heavy] [extra-heavy] [ultra-heavy]-duty type] [ratings
and types indicated]. Open-link cut-outs are not acceptable. Fuses shall
be either indicating or dropout type. Fuse ratings shall be as indicated.
Fuse cutouts shall be equipped with mounting brackets suitable for the
indicated installations.
2.13.2
Fused Switches
Fused switches shall be single-pole, manual devices with integral power
fuses of the dropout type. Fuse ratings shall be as indicated. Each
switch shall have a continuous current rating [of [400] [600] amperes rms]
[as shown], a momentary asymmetrical current rating of [20] [40] kA rms [as
