Incoming Sections
**************************************************************************
NOTE: Choose one of the following three choices for
each incoming section: a metal-clad switchgear
section, a metal-enclosed switch section, or an air
filled terminal chamber.
**************************************************************************
[The][Each] incoming section shall consist of [a metal-clad switchgear
section][a metal-enclosed switch section][an air filled terminal chamber]
[[fused][nonfused]load interrupter switch]] to the transformer. If
required for proper connection and alignment, include a transition section
with the incoming section. Connection between [circuit
breaker][interrupter switch] and transformer shall be insulated copper bus
or insulated copper cable mounted on porcelain insulators spaced no more
than 610 mm 2 feet apart.
2.2.1.1
Conductor Termination
Conductor terminations shall be designed for terminating [one][two][_____]
single conductor cables per phase and shall be arranged for conduits
entering from [below][above]. Provide cable terminations of the [modular
molded rubber][porcelain insulator] type as specified in Section 16302N
UNDERGROUND TRANSMISSION AND DISTRIBUTION.
[2.2.1.2
**************************************************************************
NOTE: When a separately enclosed, pad mounted SF6
switch is provided as the incoming
disconnecting/overcurrent protection device for the
primary unit substation, use Section 16341N,
"Pad-Mounted SF6 Insulated Interrupter Switches".
Modify Section 16341N for vault-type switches, where
applicable.

switches, but may be needed where switching is
frequent, and quick reclosing is required.
**************************************************************************
The [vacuum][ or ][SF6] circuit breaker shall be an electrically-operated,
three-pole, circuit interrupting device rated for [_____] amperes
continuous at [_____] kV and [_____] kV BIL. Breaker shall be designed for
