These are Standards, with selected
specification sections added for clarity.
This document is meant to give a brief comprehensive
description of the campus systems and call out additional
specific campus requirements that exceed standard
commercial construction specifications and code
requirements. These standards are in addition to industry
engineering standards and code requirements. This
document will point out code requirements that,
historically, have been overlooked causing substantial
additional project costs and/or compromise to project merit.
UMass Utilities Department has found these specifics
to be very beneficial and cost effective by substantially
increasing reliability and minimizing the effects of power
outages to our campus community.
Any deviation from this standard or any part thereof
must include a written comparative economic review by
the project electrical designer.
UMass Amherst Utility Department will review and
make recommendations to the Director of the Physical
Plant. The project will not proceed without written
approval by the
UMass Amherst Physical Plant Director.

UMass Amherst Medium Voltage Distribution
Systems
Overview
The Amherst Campus has two electrical distribution systems a 13.8
kV grounded wye Primary Selective system and a 2.4 kV ungrounded delta
open loop system.
The campus takes service at 13.8 kV from the utility via two
paralleled feeds on the Westside of campus and at this time generates
10MWs at 13.8 kV with future additional generation planned.
From the Westside Bus the primary selective system is distributed
throughout campus and is stepped down at each building to service
voltage utilizing 13.8 kV delta to 480/277 and/or 208/120 grounded wye. The
Westside Bus also serves two 13.8 kV radial feeds; each of these radial
feeds feed one of two separate buses at the Eastside sub-station. The
Eastside sub-station is comprised of two separate buses with a normally
open bus tie. Each bus is automatically backed up by separate utility feeds.
The Eastside Sub-station distributes additional primary selective circuitry
to buildings located on the East side of campus.
The campus 2.4 kV open loop system is derived from the campus
13.8 kV system. This system has three sub-stations; one sub-station is fed
directly from the Westside Service, one is fed from, and located at, the
Eastside sub-station and the third, also fed from Eastside, is located more
central on campus. From these sub-stations the open loop system is
distributed throughout campus and is stepped down at each building to
service voltage utilizing 2.4 kV delta to 480/277 and/or 208/120 grounded
wye building service voltage.
System Type and Approval
The 13.8 kV electrical distribution systems have either manual or
automatic switches located at each building served.
The 2.4 kV open loop system switches are all manual with one
exception; the switch located at the University Health Services building.
Building service configuration is assessed at time of design to best
serve the individual building and the campus overall operation.
Final acceptance regarding system voltage, configuration and point
of connection to the UMass Amherst Electrical Distribution system will only
be with the approval of the Director of the Physical Plant.

more incoming power sources; multiple split-bus sections; or
ring-bus arrangements.
 Applications with hot-sequence metering.
 Applications with special installation requirements, such as
transformer primary unit substations, and those requiring
special-purpose components such as grounding switches,
control power transformers, metering panels, or capacitors for
power-factor correction.
 Applications requiring unusual switchgear layouts, such as
“U-shaped” configurations.
Custom Metal-Enclosed Switchgear features:
 Rugged
11-gauge steel enclosures.
 600- and 1200-ampere load switches with duty-cycle faultclosing ratings.

 Choice
of unique response curves with S&C Fault Fiter®
Electronic Power Fuses.
 Sophisticated, pre-engineered automatic source-transfer
controls.
 Three-phase load protection. S&C open-phase detection relays
and overcurrent relays isolate three-phase loads from singlephasing and other open-phase conditions.
 Single-phase load protection. Fuses, unlike circuit breakers,
selectively isolate only faulted phases of feeders serving
single-phase loads.
 Low purchase cost compared to metal-clad gear.
 Light weight. Easier to handle than metal-clad gear.
