4 TeSys Motor Starter Solutions 8536DB0901 Structure of a Motor Starter in Accordance with UL508A Feeder Circuits and Branch Circuits 11/2009 Structure of a Motor Starter in Accordance with UL508A Feeder Circuits and Branch Circuits The feeder circuit includes all power conductors and components from the incoming feeder disconnect to the line side of the last branch short-circuit protection device (SCPD). The branch circuit includes all power conductors and components from the load side of the branch circuit SCPD to the controller load-side connections. Each branch circuit should be protected by its own disconnect and SCPD.

5 8536DB0901 TeSys Motor Starter Solutions 11/2009 Structure of a Motor Starter in Accordance with UL508A Feeder Circuits and Branch Circuits Group Motor Installations In a group motor installation, a single disconnecting means and SCPD can be used for a group of motors. The specific rules are described in NEC Sections and A. Group installations are primarily used in the following applications: 1. Fractional hp motors NEC Section (A): For several motors, each rated 1 hp maximum on a branch circuit of 600 V maximum, a single SCPD not exceeding 15 A is permitted under the following circumstances: No single motor is rated greater than 6 A The branch short-circuit device rating marked on any controller (UL508 circuit breaker, switch or contactor) is not exceeded Appropriate motor overload protection is used 2. Smallest rated motor protected NEC Section (B): The SCPD is sized for the motor in the group with the lowest rating 3. Other group installations NEC Section (C): Two or more motors of any rating, or one or more motors and other loads, where all the following conditions are met: Each motor controller and overload protection device carries a Motor Group Installation listing. Each circuit breaker (if used) is listed and is of the inverse time type. The SCPD (fuse or circuit breaker) is sized for the largest motor plus the sum of all other motors and loads. The sizing of the SCPD (fuse or circuit breaker) does not exceed the maximum allowed for overload protection of the smallest motor. Appropriate overcurrent protection is provided for non-motor loads. B. The tap conductor sizing rules for group motor installations are governed by NEC Section (D). Conductors from the load side of the SCPD for the motor group must comply with one of the following: The ampacity is not less than that of the branch circuit conductors. The ampacity is not less than 1/3 that of the branch circuit conductors, and the length is not more than 7.5 m (25 ft). The ampacity is not less than 1/10 that of the SCPD for the motor group, the length is not more than 3 m (10 ft), and the manual motor controller is marked Suitable for Tap Conductor Protection in Group Installations. Products certified for motor grouping must carry the markings on the product label or instruction sheet required by NEC and UL (such as Suitable for Tap Conductor Protection in Group Installations ) Schneider Electric All Rights Reserved 5

6 TeSys Motor Starter Solutions 8536DB0901 Structure of a Motor Starter in Accordance with UL508A Required Functions of Combination Starters 11/2009 Required Functions of Combination Starters Combination starters are the most common type of packaged motor controllers. They are called combination because of their construction and combined functions. NEC Article 430 defines the required functions of combination starters. Underwriters Laboratories, Inc. (UL) specifies the tests and verifications that the components must pass before they can be listed as suitable for use for those functions. Figure 3 depicts the four component functions that compose a complete motor branch circuit as defined by the NEC.

7 8536DB0901 TeSys Motor Starter Solutions 11/2009 Structure of a Motor Starter in Accordance with UL508A Types of Combination Starter Constructions Types of Combination Starter Constructions UL 508 is the UL safety standard for industrial control equipment. Part IV defines the component functions, construction, testing, and performance requirements of six styles of combination starters. Each of the six styles meets the requirements of NEC Article 430 for the motor disconnecting means, the motor branch circuit short-circuit and ground-fault protection, the motor controller, and the motor overload (OL) protection. Each provides adequate protection against fire or personal injury under fault conditions. The UL 508 type designations are differentiated by the actual components used to protect the motor branch circuit as illustrated in Table 2.

This disconnecting means could be one of the following: UL489 inverse-time or instantaneous-trip circuit breaker UL489 molded-case switch UL98 switch unit, either open type or enclosed For a motor starter, the disconnecting means could be a UL508 type E selfprotected combination motor controller. The sizing of the disconnecting means must meet UL508A Section A UL508 manual motor controller or switch (such as the TeSys Vario device) is certified for use on the load side of a motor's branch circuit protection. This is commonly called a load break switch. These requirements cover industrial control panels for industrial machinery (NFPA , Electrical Standard for Industrial Machinery). The following types of machines are identified as industrial machinery: Metalworking machine tools, including machines that cut or form metal Plastics machinery, including injection molding, extrusion, blow molding, specialized processing, thermoset molding, and size reduction machines Wood machinery, including woodworking, laminating, and sawmill machines Assembly machines Material handling machines, including industrial robots and transfer machines Inspection and testing machines, including coordinate measuring and inprocess gauging machines Schneider Electric All Rights Reserved

9 8536DB0901 TeSys Motor Starter Solutions 11/2009 TeSys Solutions UL98/489 An operating mechanism for the disconnecting means must have the following characteristics: Readily accessible when the enclosure doors are in the open or closed position Installed so that its operation is not restricted by the enclosure door while in the open position Operable independent of the door position without the use of accessory tools or devices Lockable in the Off position independent of the door position and when the mechanism is locked, the disconnect cannot be closed The UL98 TeSys GS disconnect switches meet these requirements. The TeSys GS1 disconnect switch requires the use of operating mechanism GS1AD010 and GS1AD020. The TeSys GS2 disconnect switch provides these features (effective in the fourth quarter of 2009). The UL489 NSF and PowerPact Circuit breakers meet these requirements when used in conjunction with a Class 92 or 91L operating mechanism and 91LH79 handle.

23 8536DB0901 TeSys Motor Starter Solutions 11/2009 Short Circuit Protection for Drives SCCR requirement in UL508A SCCR requirement in UL508A NEC Article 409, NFPA 79, and UL508A require that the SCCR be marked on all control panels. The final builder or assembler of the equipment inside the panel is responsible for providing the SCCR for the overall panel, determined by one of the following three options: Testing each panel construction and recording the construction in the follow-up procedure. With the multitude of possible product combinations within a panel, this option can require much testing and maintenance. Third party testing and certification may also be required. Purchasing previously tested constructions (combinations) from a major supplier of equipment that can be tabulated in the control or machine panel builder's procedure. Once you have all the component ratings, either use an outside service or UL 508A, Supplement SB. Using a method described in UL 508A, Supplement SB. Important: Using the interrupting rating of the main OCPD for the panel is not an acceptable practice! WARNING INADEQUATE SHORT CIRCUIT INTERRUPTING RATING Do not use the interrupting rating of the main OCPD as the SCCR rating for the controller. Failure to follow these instructions can result in death, serious injury, or equipment damage. By using discrete components to assemble a combination motor controller within a panel, and providing UL508A combination motor controller data (some listed under the Square D brand name), Schneider Electric offers solutions for achieving an SCCR that is higher than the rating of the lowestrated individual discrete component. These combinations can be found at the following websites: Square D UL508A website: 1FB03C85256EBE0047F560/$file/ul508aFrameset.htm (In the What s New area, select Fully UL508A Tested and Approved Combination Spreadsheets Now Available.)

24 TeSys Motor Starter Solutions 8536DB0901 Specific Requirements for the Canadian Market Installation and Product Standards 11/2009 Specific Requirements for the Canadian Market Installation and Product Standards Certification Process Technical Differences between Canadian and U.S. Standards The installation standard in Canada is the Canadian Electrical Code (CEC). The CEC and the NEC are similar but not 100% equivalent. The same is true for the CSA standards and corresponding UL standards (see Table 28). Some of the major differences are detailed below. As in the U.S., Nationally Recognized Testing Laboratories (such as CSA, ETL, TUV, and UL) are able to certify equipment according to these CSA standards. Refer to Acceptance of Electrical Equipment in the U.S. on page 3. The procedure is the same. Some examples of differences between the Canadian and U.S. standards that currently apply to motor starters are listed below. (Note that the TeSys product line is designed for compliance and capatibility with both the UL and the CSA requirements.) Type E combination motors starters are also recognized in Canada but Type F currently are not. Type E applications don't require the use of large spacing adapters as in the U.S. Group installation is recognized but the rules to define the common branch-circuit protection setting is quite different. Industrial control panels must meet CSA C22.2 No. 14 Elevator equipment appliances must comply with the specific CSA Nr. B44.1 standard. Product marking requirements differ slightly.
