o. MODIFICATIONS OF LIGHTING FUSE PANELS
6.1 General
6.1.1 The existing lighting fuse panels in the Court House will be
modified to accommodate the new 3 -phase, 4 -wire electrical sys-
tem. The three mains in these fuse panels are bare copper bus
bars, with lugs at the bottom and two sub -feed fuses at the top.
Lighting branch circuits tap off the bus bars through two -pole
open -blade knife switches and plug fuses. At present, the neu-
tral is both switched and fused.
6.1.2 In modifying the fuse panels, the branch circuit wiring will be
reconnected so that only the ungrounded conductors are fused, and
all grounded conductors are solidly connected to the system neu-
tral. In each fuse panel, two solid neutral copper bars, one in
each side gutter, will be installed. The branch circuit conduc-
tors presently connected to the neutral fuses will be removed and
reconnected to the new neutral bars. The new neutral bars will
be of the type currently used in circuit breaker panelboards, and
will have ampere ratings as stated in subsequent paragraphs. An
insulated jumper conductor, of the size stated in subsequent para-
graphs, will be used to interconnect the two bars in each fuse
panel. The new neutral bars, and all wires connected to them,
shall be electrically isolated from ground.
6.1.3 The fourth feeder conductor, installed as shown on the Circuit
Schedule, will be the neutral of the new four -wire system. One
49
of the neutral bars in each fuse panel shall be solidly connected
to the neutral feeder conductor. The connection may be a gutter
tap, or the feeder conductor may be cut and connected by means of
a two -wire lug. In any case, the neutral bar shall carry only the
unbalanced current resulting from the branch circuits connected
thereto. Only solderless, bolted lugs and connectors will be used.
Split -bolt type connectors shall not be accepted.
6.1.4 Spacing of the fuse panel bus bars is inadequate for bare con-
ductors. In each of the fuse panels this will be remedied as
follows: Remove the two raised bus bars by unbolting their taps.
Spiral wrap the length of each bus with three thicknesses (2/3
overlap) of polyester film electrical tape. Only "Permacel No. 254"
or "Scotch No. 57" in either 5/8 or 3/4 inch width, shall be used
to wrap the bus bars. Cut and remove sections of the tape wrapping
only where necessary to reconnect the taps. All connecting sur-
faces shall be clean and bright before re -installing the bus bars.
Re -install and reconnect the bolted taps.
5.1.5 In each fuse panel reconnect the ungrounded branch circuit con-
ductors in such a manner as to cause (as close as practical) equal
loading on each of the three bus bars. If common -neutral circuits
exist, the two ungrounded conductors of such circuits shall be
connected to fuses controlled by the same two -pole knife switch.
Following panel modification and circuit rearrangement, a new dir-
ectory card shall be made for each fuse panel. The panel directory
will be typewritten or neatly lettered with drafting ink.
6.2 First Floor Fuse Panel
6.2.1 Both of the two neutral bars to be installed in the First Floor
fuse panel shall be rated at not less than 200 amperes and have
not less than 30 screw type terminals for branch circuits. The in-
sulated jumper conductor interconnecting the two neutral bars shall
be 1/0 AWG.
6.2.2 The sub -feed to the circuit breaker panel in the County Clerk's
vault will be removed as a bus bar tap, and will be protected by
a circuit breaker. The breaker will be mounted near the top of
the fuse panel on one of the slate sidewall barriers. The breaker
will be located to provide the most clearance to other devices with
50
the panel. The molded case breaker shall be fed with a #4 AV
bus tap connected to the line side of the sub -feed fuses. The
breaker shall be 2 -pole common trip, and rated at 240 -volt a -c,
50 -ampere trip, 7500 ampere interrupting capacity. The breaker
shall have a 100 ampere frame (E -frame).
6.2.3 The present sub -feed fuses will be replaced with 225 -ampere dual -
element Fusetron fuses.
5.3 Second Floor Fuse Panel
6.3.1 The two neutral bars, and jumper conductor to be installed in
the Second Floor fuse panel shall be as specified in paragraph
6.2.1 above.
6.3.2 The sub -feed circuits tc the license department breaker and the
Christmas lights fuse box will be removed as bus taps, and treated
in the manner specified in paragraph 3.2.2 above. The trip rating
of the feeder breaker for the license department will have a trip
rating of 30 amperes. The feeder breaker for the Christmas lights
will have a trip rating of 50 amperes. In other respects the
breakers shall be as stated in paragraph 5.2.2.
6.3.3 The present sub -feed fuses will be replaced with 150 -ampere, dual -
element, Fusetron fuses.
6.4 Third Floor Fuse Panel
6.4.1 Both of the two neutral bars to be installed in the Third Floor
fuse panel shall be rated at not less than 100 amperes and have
not less than 20 screw type terminals for branch circuits. The
insulated jumper conductor interconnecting the two neutral bars
shall be #4 A%CG.
6.4.2 The present sub -feed fuses will be replaced with 100 -ampere.
dual -element, Fusetron fuses.
6.5 Fourth Floor Fuse Panel
6.5.1 The two neutral bars, and the jumper conductor to be installed in
the Fourth Floor fuse panel shall be as specified in paragraph
6.4.1 above.
5.5.2 This fuse panel has no sub -feed fuses. The feeder conductors for
the Attic circuit breaker panelboard shall be connected at the
bottom of the fuse panel. That is, the load resulting from the
Attic panelboard shall not flow through the fuse panel's bus bars.
51
7. PHASE IDENTIFICATION AND MARKING
7.1 General
To assist in obtaining balanced loading of the three phases in the new
service, all feeder conductors shall have phase markers applied during
construction. The markers will be carefully applied so as to be readily
identifiable at panelboard terminals. All fuse and circuit breaker
panelboards in the Court House, and in the jail building shall be
marked to indicate the type of feeder circuit present. Conductor and
voltage markers will be standard stock items printed on non-conductive
Vinyl Cloth. The catalog or stock number of markers specified below
are those of the W. H. Brady Company and shall not be substituted with-
out the Engineer's approval.
7.2 Conductor Marking
7.2.1 In the service equipment, each of the service conductors shall be
assigned a phase letter. The letters shall be "A", "B", and "C",
and the choice of phase identification shall be made arbitrarily.
That is, the phase identifications shall be for the Court House
and jail building only and will not necessarily reflect the util-
ity company's notation, sequence or rotation. Once the choice has
been made, and the service conductors marked, the phase identifi-
cation shall be held true throughout the entire electrical dis-
tribution system.
7.2.2 Each feeder conductor, entering and/or leaving every fuse and cir-
cuit breaker panelboard in the Court House and in the jail build-
ing, shall be identified and marked in agreement with the phase
letters assigned at the service equipment. This will not apply
to individual fuse boxes such as motor disconnecting switches.
7.2.3 The conductor markers shall be Brady Stock No. B-500 series, in
the 1 1/2 inch length. The markers will be placed near the lugs
or terminals, and shall be readable after installation without
moving any wire.
7.3 Panelboard Marking
7.3.1 Fuse and circuit breaker panelboard markers will be placed above
the directory card or other location that is conspicuous upon
opening the door. In panelboards where 3 -phase, 4 -wire is pre-
sent, the markers shall be "THREE PHASE" "208 VOLTS", "SINGLE
52
PHASE" "120 VOLTS". Where two phase wires and the neutral are
present, the markers shall be "SINGLE PHASE" "208 VOLTS" "120
VOLTS". In every case the markers shall indicate the voltages
and number of phases (one and/or three only) present in the panel.
7.3.2 The markers used shall be Brady Stock Nos. CV -298, "SINGLE PHASE",
CV -31B, "THREE PHASE"; CV -AB, "120 VOLTS"; CV -6B, "208 VOLTS".

This preliminary report describes the existing electrical distribution
system at the Weld County Court House and Jail, and sets forth alternate
methods of revising the system for present and anticipated loads.
SUI*AARY
An inspection of the court house distribution system was made by Miner and
Miner, Consulting Engineers, Inc., to determine the adequacy and condition
of the existing system. Particular attention was given to those points which,
in the past, caused operational difficulties. Current and voltage readings,
taken at the main switches and distribution panels, indicated that the ser-
vice and feeder conductors are large enough for the anticipated loads. The
conductor insulation, except from the main switches to the service head, is
in fair condition and is usable.
Modification of the service is required because the Home Light and Power
Company has plans to convert the alley distribution system to 208/120 -volt,
3 -phase, 4 -wire. A change could best be effected with least interruption of
power by relocating the service at the court house instead of the boiler roam.
A service at the court house.is, however, more expensive than converting the
existing service to 3 -phase, 4 -wire. Therefore, it is recommended that the
service be left at the existing location, but revamped.
The principal deficiency in the service equipment is the lack of a distri-
bution panel, which would furnish protection to the branch circuit feeder
and panels. The present branch circuit panels are acceptable if modified,
with the exception of the boiler room power panel which should be replaced.
Kilowatt-hour meters and metering transformers, presently located in the
boiler room, should be replaced and relocated outdoors.
Lighting branch circuits in the court house are overloaded, which is primarily
caused by the connection of outlets on the lighting circuits. Several possible
corrective measures were studied. The installation of an outlet breaker panel
in the attic was found to be the most economical. Heavily loaded outlets can
be disconnected from the present lighting circuits and connected for service
fram the attic panel.
1
The lighting fuse panels require reconnection to balance the load on the 3,
phase service. Neutral wires, presently fused, should be reconnected to a
solid neutral bar.
Following is a summary of the estimated costs of recommended improvements,
with the first and third items being of prime importance.

kSstino Wiring
The court house and jail are presently serviced by a 240 -volt, 3 -wire, 3 -
phase service and a 240/120 -volt, 3 -wire, single-phase service. Individual
banks of transformers for each service are located on an H -frame wood pole
platform in the alley adjacent to the jail. Four -hundred ampere, fused dis-
connect switches are situated on the outside rear wall of the jail and housed
in a common metal cabinet. This is the only fused protection ahead of the
branch circuit lighting fuse panels and the jail power circuits. The court
house power circuits have branch circuit protection from a fuse panel in the
sub -basement. See Existing Power Circuit Feeder Arrangement sketch on page 5.
Both main circuits are junctioned in a common metal cabinet in the basement
(boiler roam) of the jail. The metering transformers for the kilowatt-hour
meters are located at this junction. The jail light and power circuits are
tapped from the main lead in the junction box, with this main lead continuing
to a second junction box in the court house sub -basement. The lighting cir-
cuit mains go directly through the junction box to the basement floor lighting
fuse panel. The outgoing bus in this panel is fused and leads terminate there
for the first floor panel. Each panel has fused outgoing bus bars which serve
the succeeding panel. All panels have fused branch circuit neutrals. Out-
lets are connected to the lighting circuits and in most cases are switched
2
n
with the lights. The branch circuit wiring is not polarized. See Existing
Lighting Circuit Feeder Arrangement sketch on page 6.
Three branch circuit fuse panels and one breaker panel in the jail serve
the lighting and outlet circuits both in the jail and boiler roam. A circuit
breaker for the electric range is located over the door to the second floor
stairway. The power circuit main feeders to the court house terminate at
branch circuit fuse blocks in the sub -basement panel. The main loads from
this panel aces (a) a 25 -horsepower fan motor in the basement, (b) a 30'
horsepower elevator motor, also in the basement, (c) a 15 -horsepower fan
motor in the attic, and (d) a 5 -horsepower fan motor in the attic. All
motors have wound rotors and have individual starting and protection equip-
ment.

are not used, however, and will not require additional equipment until placed
back in service.
The sub -basement fan motor is in continuous service and has defective starting
and protection equipment. It is recommended that the defective switchgear
be replaced with a combination starter and suitable remote controls. The
estimated cost of materials and labor for this replacement is $400.

REVISIONS
Gene
The suggested revisions herein encompass three basic needs with respect to
the wiring of the court house and jail. These needs are: (a) new service,
including a main distribution panel, (b) installation of a new breaker panel
in the court house attic for outlet circuits, and (c) revision of existing
lighting circuit fuse panels and panel wiring.
Althoughthere is an urgent need at this time to separate the outlets from
lighting circuits, it is recommended that the service entrance revisions be
given first priority to not only provide adequate branch circuit protection
but also to facilitate the division and rearrangement of all circuits.
Service Entrances
Preliminary investigation shows that the fused disconnects in the existing
service are in poor condition, with contacts clamped together to maintain
electrical connection. These disconnects are not safe to operate nor do
they provide the required branch feeder protection. The kilowatt-hour meters
and metering transformers should be relocated outdoors. The Home Light and
Power Company has tentative plans to change the alley distribution system
to 208/120 -volts, 4 -wire, 3 -phase.
To make the system adequate for present needs and a 50 per cent load increase,
it is recommended that a new service and a main distribution panel be installed
to serve both the lighting and power loads. In order to be near the center
of load and to reduce the required feeder sizes and lengths, the service would
normally be located at the southwest corner of the court house. However, cost
estimates show that a 4 -wire, 3 -phase service at the boiler roam, utilizing
sections of the existing service conduit and wire, is approximately $1100 less
expensive than a new service. See Planned Feeder and Panel Arrangement sketch
on page 8 .

Cutlet Circuit%
The complete separation of outlets from lighting circuits in the court house
cannot be made within economical limits. The most satisfactory compromise
is to supply circuits to the most heavily loaded areas and also where addi-
tional loads are anticipated. The only access to these areas is in the pass-
ages adjacent to the air ducts, which extend from the attic to each roam.
Therefore, it will be necessary to mount a circuit breaker panel in the attic
and install conduit from the panel to junction boxesat the openings of the
air duct chases in the attic. Flexible armored cable between junction boxes
is required because of insufficient space in the chases to install and support
conduit. Wiremold will be used to complete the runs to the outlets.
The following rooms in the court house will require outlet circuits:

J.iahtina Circuit Fuse Panel
Conversion of the distribution voltage to 208/120 -volt, 3 -phase will result
in an overload on one phase of the equipment, unless the lighting circuit
loads are reconnected to balance the phase loads. Load balance could most
easily be accomplished by converting the single-phase fuse panels to three-
phase and equalizing the phase loads at each fuse panel. The existing panels
cannot, however, be readily redesigned for three-phase use. An approximate
load balance can be obtained by reconnecting each successive panel to alter-
nate phase leads. A fourth feeder conductor is required at each panel.
It is also recommended that the branch circuit neutrals at each fuse panel
be reconnected to a solid neutral bar; each neutral is presently fused.
COST ESTIMATES
Service Entrance%
These calculations are to compare the costs of three alternate service
entrances to replace the existing service to the Weld County Court House
and Jail. All alternates are based on a change in voltage supply from
240 -volt, 3 -phase, and 240/120 -volt, single-phase to 208/120 -volt, 4 -wire.
3 -phase.
10
Service entrace, as shown in Option °A°, is a modification of the existing
service at the boiler roam. The service will utilize the existing conduits
and wire from the outside fuse panel to the boiler roam junction box, and
from the junction box to court house subbasement power panel and feeder
junction box. The existing fuse panel outside will be replaced by a junction
box for the metering transformers. Larger conduit, wire, and service head
are required for the outside service. The main distribution panel will be
mounted on the east wall, north corner of the boiler roam, adjacent to the
sub -basement tunnel entrance.
Service entrance, as shown in Option °B°, enters directly into the air duct
on the west wall, south corner of the court house, and requires two 3 -inch
holes to be drilled in the three-foot bearing wall between the fan room
coolers and the sub -basement. No holes are required in the outside walls.
Service entrance, as shown in Option °C', requires two 3 -inch holes to be
drilled in the south wall foundation, west corner of the court house, and
two holes through the ten -inch section of wall between the fan room and sub-
basement. For either service, the main distribution panel will be located
on the south wall of the sub -basement, adjacent to the boiler room tunnel
entrance. Both services require the setting of a six-inch steel pole to
which service conduits and incoming overhead lines will be attached.

Outlet circuit breaker panels for each floor of the court house cannot be
economically provided because of limited access to the various rooms.
Concealed wiring to the outlets can be installed only in chases which extend
from the attic to each room and a circuit breaker panel mounted in the attic
will afford the shortest conduit and wire runs to the outlets.

Fuse Panel Revision
The court house lighting circuit fuse panels require the installation of a
solid neutral bar and the reconnection of branch circuit neutrals to the
neutral bar.
Supplying separate feeders to each panel is desirable but is impractical and
economically not justified. Likewise, supplying separate feeders to each
set of two panels is expensive. The most economical and feasible means of
furnishing three-phase power to the panels is to utilize the existing single
feeder to all four panels, and install a fourth wire to each panel through
existing conduit. The conduit is large enough to accommodate the extra wire
and the existing feeders are large enough for the total load. It will not
be known prior to the actual installation whether the extra wire can be
pulled from the sub -basement to the basement floor fuse panel without pulling
out the old feeders. It is doubtful that the feeders can be pulled out
without cutting the conduit in the tunnel below the fuse panel. All new wire
will be required if the conduit is cut.

Following are the estimated costs of the recommended changes in the electrical
distribution system at the Weld County Court House. The service entrance at
the boiler room was selected in preference to the alternate service entrances
at the court house on the basis of cost comparison, and to eliminate the
possible marring of appearance of the court house where outside metering
equipment would be installed.

If all of the changes cannot be effected at one time, it is recommended that
the service entrance and fuse panel revisions be given first priority. The
service and fuse panel revisions must be made concurrently to balance phase
loads.

Dear Sir:
l:A
P. 0. BOX 749
TELEPHONE EL 2-270e
This letter is to give official certification of the completion of the
work and inspection associated with the rewiring of the Weld County
Court House and Jail. The work was performed by Burke Electric Service
in strict accordance with the written specifications prepared by Miner
and Miner, except in the few cases where deviation was permitted by
the Resident Engineer of Miner and Miner. These deviations concerned
only the routing of branch circuit conduits and was done to facilitate
their installation.
Final inspection of the rewiring project, which began during the first
week in November, 1960, was made on March 14, 1961. The major portion
of the work had been completed by February 1, 1961, but final inspec-
tion was delayed pending the receipt and installation of service panel -
board doors.
It must be pointed out that Mr. Burke and his staff performed all phases
of the work in a thoroughly professional manner, with a high degree of
technical skill. Mr. John Watson, your Building Supervisor, must also
be complimented for his cooperation and aid, without which the job would
have been considerably more difficult.
The major problem encountered in conjunction with the rewiring concerned
the unsatisfactory operation of the Otis elevator after connection to
the new power system. Considerable reduction in starting, and running
torque was evidenced. Some reduction was anticipated because the motor
voltage was changed from 240 volts to approximately 220 volts which is
the rated value. We have written to the Otis Elevator Company about
the allowable voltage variation for proper operation. They reaffirmed
our belief that the elevator motor was designed for 220 volts with plus
or minus 5 percent tolerance. This places the lower limit at 209 volts
which is less than can be expected at any time at the Court House. Actual
readings taken at the motor after reconnection averaged 215 volts. Voltage
readings taken by the Otis Elevator service man on March 10, 1961, showed
the voltage to be balanced at 220 volts. The Otis people have made some
adjustments in the circuit controls which have improved the operation,and

and they are continuing their investigations. The elevator is satis-
factory at this time, although not as expected.
Should other problems arise concerning the elevator or other phases of
the work, we would appreciate their being directed to our attention.
