Many state, county and city electrical jurisdictions have similar requirements. A UL Field Evaluation is an accepted approach to meet this requirement; UL conducts an unbiased, independent assessment of products at a specific location to essential requirements of applicable product safety standard(s). UL's engineering assessment informs regulating authorities who make product and related installation approval decisions. Please note that the regulating authority for the final installation site provides final approval of this equipment and the installation. This project's purpose was to evaluate a product that was not Listed or otherwise certified by a testing laboratory recognized by the authority having jurisdiction. Products undergoing this evaluation process do not acquire a UL Listing, UL Recognition, or UL Classification. UL has not established factory Follow -Up Services to determine the conformance of any subsequently produced, relocated, or otherwise altered product(s) or system(s). Installation model codes are referenced in this document where necessary to ensure the product can be properly installed according to the code (e.g. National Electrical Code, NFPA 70). At the request of Mr. Doug Halvorson of Turn -Key Controls Ltd., a Field Evaluation project was initiated. A Final Evaluation was completed at: • Durham Advanced Wastewater Treatment Facility, 16580 SW 85th Avenue, Tigard, OR Based on the inspection, testing, and evaluation completed, UL considers the product to be suitable for application of the Field Evaluation Product Mark and for use in accordance with any conditions of acceptability stated in this report. 2 Conditions of Acceptability Except where otherwise stated in the product description and evaluation sections of this report, this evaluation and the application of the Field Evaluated Product Mark is subject to the following Conditions of Acceptability. 2.1 Except for like -for -like component replacement in the event of component failure, no change or addition to the product or system shall be made that would alter its construction, operation, function, layout, source of supply, physical location or operating environment. If such changes or additions to the product occur, the Field Evaluated Product Mark shall be considered invalid, and a separate evaluation shall be required to determine compliance with applicable product safety standards under the changed conditions. 2.2 The completed evaluation and application of the UL Field Evaluated Product Mark by UL does not assume liability on the part of UL and does not relieve the manufacturer, installer, user, or other relevant parties of their responsibilities. The product evaluation is based on adherence to sound engineering practices, and compliance with the applicable product safety standards and installation code. 2010 - 5634 -FE Field Evaluation Services Report Page 3 of 14 2.3 This evaluation considered the risks associated with electric shock, fire, and casualty hazards as specified in the evaluation section of the report only. No other hazards were evaluated during this evaluation. 2.4 Unless otherwise stated in the product description, this product was evaluated for installation in an indoor, dry, normal environment only. The product was not evaluated for installation in any hazardous classified location as defined in the latest edition National Electrical Code as adopted by the National Fire Protection Association. The product was not evaluated for installation in an environment subject to rainfall, water spray, steam, or exposure to any corrosive chemicals that deteriorate the enclosure or components. 2.5 The UL Field Evaluated Product Mark shall not be considered as equivalent to the UL Listing Mark, UL Recognized Component Mark, or UL Classified Product Mark. The UL Field Evaluated Product Mark indicates compliance with the applicable parts of the Standards referenced in Section 3 at the time the Mark was applied, and considering only the final installation site. The applicable parts included in the evaluation are the construction review, markings, and those testing protocols that are non - destructive. 3 Referenced Standards • UL 845, Motor Control Centers, 5th Edition, Revised 08/31/2005 4 Product Description Equipment Name: Motor Control Center Description: The equipment is a new CSA certified motor control center that has five sectons. The preliminary evaluation was performed under Project 09CA22264. Manufacturer: Siemens Model Number: SO Serial Number: 0811 -920 4.1 Nameplate Data Electrical Ratings Volts 480 Vac Amps 600 A Phases 3 Wires 4 Frequency 60 Hz Short Circuit Current 30,000 Amps 2010 - 5634 -FE Field Evaluation Services Report Page 4 of 14 4.2 Field Evaluation Label UL Engineers have determined that the subject product complied with the Standards referenced in Section 3 and the following UL Field Evaluated Product marks were applied. • FE- 341934 Date Applied: 10/14/2010 5 Evaluation Discrepancies This section details the non - compliant findings of the preliminary evaluation. Unless corrective actions are described, a final evaluation is necessary to complete all remaining tests and verify that changes have rendered the equipment compliant. 5.1 Nameplate Markings Reference: UL 845, 5th Edition, Section 6.1 to 6.3 The following information shall be given by the manufacturer for each section: a) Manufacturer's name or trademark b) Type designation, serial number, or equivalent c) Section number (i.e. Section 1 of 5, Section 2 of 5 etc.) d) Electrical ratings as noted below 1) Voltage (Volt, V, Vac, Vdc); 2) Phase (0, phase); 3) Frequency (Hz, hertz); 4) Horizontal power bus ampacity (i.e. 600 A) 5) Vertical power bus ampacity (i.e. 300 A) 6) Bus short- circuit current ratings (A rms sym, or A dc V max). e) Enclosure type; and f) Termination and wiring information, as follows: 1) Tightening torque for field - installed conductors (lb -in, or N-m). 2) Required temperature rating for field installed power conductors ( °C); 3) Material requirements for conductors (Cu, Al, Cu -Al, Al -Cu) Discrepancy: The MCC was provided with two nameplates on two sections. Provide nameplates that include the information as noted above for each section or provide one nameplate that shows that it covers all five sections. Corrective Action: One of the nameplates was removed, and the other was revised to show that it covers all five sections. 2010 - 5634 -FE Field Evaluation Services Report Page 5 of 14 5.2 Horizontal Bus Rating Reference: UL 845, 5th Edition, Section 5.3.2 and 8.2.16.2 The horizontal bus of motor control center must have a continuous current rating of 600 A or higher. Discrepancy: The horizontal bus supplying power to each section as well as the supply bus to the motor control center (MCC) is undersized for the rating of the overall MCC. The bus is 1 -1/2" x 1/4" with a cross - sectional area of 0.375 square inches, hence its rating being 375 Amps max. The MCC is rated 600 Amps. Since the horizontal bus must have a continuous current rating of 600 A or higher, de- rating the MCC is not acceptable. Install another bus of 1 -1/2" x 1/4" on top of the existing horizontal bus and supply connection bus to increase the rating to 600 Amps or provide documentation showing that the current configuration is adequate for 600 Amps. Corrective Action: Documentation was provided showing the motor control center is suitable for 600 Amps in the current configuration. 5.3 Short Circuit Current Rating Reference: UL 845, 5th Edition, Section 5.4.4 The bus structure (horizontal and vertical bus) of a motor control center shall have a short circuit current rating. The rating shall be the applicable rating from Table 3. Discrepancy: The short circuit current rating could not be determined since the circuit breakers used in many of the units are instantaneous type and are not rated. According to the referenced standard, when the short circuit protective device is an instantaneous -trip circuit breaker, it shall be evaluated by design tests. Provide test data information showing that when using the circuit breakers currently installed in the units, the short circuit current rating of 42 KA rms sym. is appropriate. Corrective Action: Information was provided showing that the circuit breakers were rated 30,000 Amps; therefore, the main nameplate was revised to show a SCCR of 30,000 Amps instead of 42,000 Amps. 2010 - 5634 -FE Field Evaluation Services Report Page 6 of 14 5.4 Overload Rating in the Units Reference: UL 845, 5th Edition, Section 6.2.2 The following information shall be given by the manufacturer for units: a) electrical ratings (see Clause 5.1.2); and b) technical information, as follows: 1) wiring diagrams or tables; and 2) current element tables for overload relays Discrepancy: The units that contain the Profibus Current Transformer type units (that communicate with the drives and PLC) are marked based on the rating of this device (2.4 to 25 Amps) rather that the range of the adjustable motor overload relay connected to the motor contactor. Revise the nameplates to show the overload relay range based on the overload relay connected to the contactor. Corrective Action: The nameplate information for these units was revised to show the correct overload ratings. 5.5 Fuse Replacement Markings Reference: UL 845, 5th Edition, Section 6.3.45 With reference to Clauses 8.2.14.1 to 8.2.14.5, where a branch - circuit type (other than supplementary) fuse is provided and the fuseholder will accept a fuse having a higher current rating than as specified in Table 12, a marking specifying the maximum fuse size shall be provided near the fuseholder. Discrepancy: Fuse replacement markings specifying the electrical ratings of replacement fuse sizes were not found at the fuseholder locations or on a chart provided in some of the units. Provide fuse replacement markings at each fuseholder indicating the voltage and current at the minimum. Alternatively, provide a chart indicating the fuse identification and replacement information specified above. The chart shall be permanently affixed so that is visible when the door or cover is opened. The markings or chart are to be permanent and suitable for the intended installation environment. Corrective Action: Fuse replacement markings were provided. 2010 - 5634 -FE Field Evaluation Services Report Page 7 of 14 t 6 Evaluation Details The following specific areas were evaluated using the methods described.
