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". 53 DESCRIPTION OF SCHEDULE UNITS 1.

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.

GENERAL DISCUSSION $ 4,900.00 4,140.00 1,980.00 400.00 $11,420.00 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. Tables I and II show current and voltage readings taken under near normal load conditions, but with all boiler equipment off and with no extra equips. ment (electric heaters, individual roan coolers, etc.) turned on.

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. 4 /.

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.

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.

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.

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. 13 The alternate costs of revising the four court house panels and supplying new wire is as follows: Alternate 1: Revise panels and supply neutral wire only.

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 rt Commissioner Schultz, Chairman March 16, 1961 Page Two 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.
