Integrated Equipment Ratings Typical Specification Downstream panelboards must be either Fully Rated or INTEGRATED EQUIPMENT RATED with the upstream protective device. For INTEGRATED EQUIPMENT RATED panelboards, each panel must be labelled to indicate: 1) tested IER ka rating 2) specific upstream protective device 3) permissible branch devices 4) panel board designation 5) voltage All ratings contained herein are based on the latest data available at time of printing. A complete listing of Series Ratings is available from the CSA website: http://directories.csa-international.org/ using the Class Number 1431-01 or the UL website: http://database.ul.com/cgibin/xyv/template/lisext/1frame/index.html using Keyword search series connected.

Introduction Low voltage distribution systems require the general need of continuity of supply and safety to personnel and equipment. The reliable and safe distribution of electrical power is dependent upon the use of protective devices for making and breaking circuits, detecting the presence of fault currents, and for isolating a faulty circuit with least disturbance to the system. In addition, the assemblies which house and provide interconnection points for protective devices play an important role in this reliability and safety perspective. All these matters must be considered when designing, developing, operating and maintaining a modern electrical power system. Electrical standards of Canada and the USA provide two different methods of applying assemblies such as panelboards, switchboards, etc. into an electrical system: Fully Rated The short circuit protective devices at all levels have a rating that matches or exceeds the system available fault level. Series Rated or Integrated Equipment Rating (IER) The electrical standards permit the use of downstream equipment (such as moulded case circuit breaker panelboards) with protective devices having lower interrupting ratings than the available system fault level when protected by an upstream fully rated device. This "series" application of upstream and downstream device must comply with CSA/UL standards which require that any installation supplied in this fashion makes use of devices which have been tested as a series combination. Description The upstream protective device may be either a moulded case circuit breaker or a fuse (Class R, or L). In the event of a major fault both upstream and downstream devices will open. The let-through current is limited by the simultaneous opening of both devices to a value which can be safely cleared. The upstream device thus protects the lower-rated downstream device. The resultant series rating when applied to a product assembly is known as an Integrated Equipment Rating. Circuit Breakers A downstream circuit breaker tested in combination with an upstream circuit breaker may be assigned a series connected rating. These circuit can utilize either thermal-magnetic trip units or electronic trip units and can be 80% or % rated. When, the downstream circuit breaker is tested in a piece of distribution equipment, such as a panelboard, the net result is that the panelboard will have an Integrated Equipment Rating. Design of the equipment and selection of is based on short circuit interruption tests specified and witnessed by CSA/UL. Because the devices and the equipment are tested as a system, the manufacturer can provide and warrant this Intergrated Equipment Rating. Fuses Don't apply fuses using the up-over-down method. This graphical/empirical method of sizing an upstream current limiting fuse to protect downstream moulded case circuit has been recommended by some fuse manufacturers. This selection process is no longer permissible as the electrical standards will now recognize only tested combinations. Moreover the Up-Over-Down method could lead to erroneous and unsafe conclusions because it treats the circuit breaker as a device with only a static interrupting capacity characteristic. In fact, the circuit breaker has a number of dynamic characteristics at play during fault interruption... one of the most dominant being the speed of contact opening. These dynamic characteristics vary greatly between circuit breaker designs. For proper application of current limiting fuses, always refer to recommendations by the manufacturer of the circuit breaker and its assembly, which are based on actual test data. Circuit Protection and Continuity In applying Integrated Equipment Ratings, the design engineer should understand that this technique does not jeopardize circuit protection and continuity when compared to fully rated equipment performance. Integrated Equipment Ratings generally apply to the 600 Ampere and lower feeder level. At the feeder level (i.e. upstream breaker), the device is fully rated. The user level device (i.e. downstream breaker) is a standard interrupting capacity device. Whether the downstream breaker is fully rated (see figure 1) or IER rated (see figure 2), co-ordination and selectivity remain the same. In BOTH Fully Rated and Integrated Equipment Rating systems, a downstream fault current higher than the instantaneous trip setting of the upstream breaker may result in both circuit tripping. This situation is usually acceptable when one considers that the vast majority of faults are overloads or limited arcing faults where time-current selectivity still applies. Circuit continuity for Integrated Equipment Rating systems is the same as for fully rated systems when applied at 600 Amperes and below. 5

Fault Calculations/Protection of Downstream Devices and Equipment When applying Integrated Equipment Ratings it is only necessary to evaluate the available fault current level (in symmetrical ka) at the line terminals of the main or upstream device. This is sufficient because: The upstream/main device (circuit breaker or fuse) is fully rated for the available fault level. The upstream device and downstream assembly have a test-proven Integrated Equipment Rating to meet or exceed the available fault level. The let-through current and energy below the downstream breaker is at or below the level of let-through for the downstream device at its rated fault capacity. In this manner downstream cables and loads are protected as normal. Selection To develop a series connected protective system, it is suggested that the design engineer, after completing preliminary steps: Define available fault current at the line terminals of the upstream breaker. Select an upstream breaker with an interrupting rating equal to or greater than the available fault current. Verify the Integrated Equipment Ratings of the selected equipment by referring to the tables in this brochure. Tables show the maximum main or upstream fuse or breaker frame ampere rating. The IER combination applies from the minimum to the maximum fuse or breaker frame rating. Confirm, during commissioning, that the correct have been installed by checking the nameplates appearing on the equipment. AVAILABLE FAULT CURRENT Motor Loads In most applications, panelboards feed non-motor or low inductance loads, and therefore, there is no requirement to consider motor contribution when selecting series combinations using the IER charts. However, if the downstream panelboard feeds motors through its branch circuit then due consideration should be given to the motor fault contribution. CEC Part 1, Appendix B, Notes on rules; 14-014 states that "Where motors are connected in the system between the series connected devices, any significant motor contribution to the fault current should be considered. It is generally agreed that the contribution of asynchronous motors to the short circuit current may be neglected if the sum of the rated currents on motors connected directly to the point between-the series connected devices is 1% or less of the interrupting rating of the downstream circuit breaker. (See IEC Publication 60781)." For those situations where the total motor load is above this level, fully rated circuit should be considered. CSA/UL Standards Moulded case circuit are designed and tested to CSA Spec. C22.2 #5.1 and/or U/L #489. Both these standards include the test requirements for verifying a series combination rating. The short circuit tests are performed with the upstream device and the downstream circuit breaker mounted in the smallest enclosure in which each is to be used. Two short circuit shots are required; one where the fault is applied with both devices closed, the other by closing the downstream breaker on the fault. After the short circuit shots, the downstream device must pass a calibration check carrying twice rated current and a dielectric withstand test. An intermediate interrupting test may be required by the testing agency if it is deemed necessary to verify the downstream breaker over the entire range of fault current. The short circuit test must be repeated if a manufacturer requires a series rating with the downstream circuit breaker mounted in a panelboard. The series requirements which are now included in C22.2 #5.1 are in the CSA Canadian Electrical Code Part I, Rule 14-014, "Series Rated Combinations".

Figure 3 - Typical Panelboard Label Panelboard Marking Downstream panelboards containing branch circuit which are being applied on the basis of a series rating must be clearly marked to indicate the following: (Figure #3) Short circuit rating Upstream breaker type breaker type Apply and replace prudently since the interrupting capability of an Integrated Equipment Rating panelboard is based on specific upstream and downstream devices as marked on the panelboard label. It is absolutely essential that any additional or replacement be of the same type and rating as indicated on the label. Other Applications of Series Ratings (IER) Series ratings can also be applied under the following: Any fully rated breaker can be applied upstream, downstream or in the middle of any of the series ratings stated in tables. Any series rating stated in the tables may have additional series rated branch of the exact same type further downstream in that rating. Combining series ratings are allowed under certain conditions. Main and branch ratings may be combined if: Breakers A, B, and C are in series respectively from main to branch. Breakers A and B series rate together Breakers A and C series rate at the same fault level (or higher). Then it is allowable to use A, B and C together at the A-B series rating. It is improper to combine series ratings under the following condition: Breakers A, B, and C are in series respectively from main to branch. Breakers A and B series rate together. Breakers B and C series rate at the Breaker B interrupting rating level. It is not allowable to use A, B and C together at the A-B series rating. However combining multiple overcurrent devices as in this example, can be accomplished if all devices in the series combination have been tested together. Summary The utilization of this technique will result in a number of benefits without sacrificing either safety or reliability: Reduction of Panelboard initial cost and size, since downstream are rated only for the prospective short circuit fault current at their point of application. Requirement of fault calculations for downstream product selection is eliminated. Downstream circuit are readily available, volume produced and standard interrupting type. 9
Application and Worked Example Figure 4 shows a typical schematic that demonstrates the use of Integrated Equipment Ratings. The main Service Switchboard includes a 1600 amp incoming moulded case circuit breaker which feeds a power panelboard in a distribution section of the board. It is assumed that the fault current of 40 ka is available at the power panelboard bus since the main 1600 amp circuit breaker provides little or no current limitation. The diagram also indicates that a 400 amp branch breaker in the distribution section feeds a downstream Lighting and Distribution Panel. Using the IER Charts The selection of this downstream lighting and distribution panelboard using Integrated Equipment Ratings is achieved as follows: Step 1 Look at the given information. (Figure 5) System Operating Voltage: 600Y/347V Fault Level Available: 40kA Upstream Breaker Amps: 400A Downstream Breakers Amps: 2 and 3 pole 15-150A, 1 pole 15-30A Step 2 Determine the type of panelboard. System operating voltage is 600Y/347. There are two types of panelboards that operate at this voltage: Pow-R-Line 2a and 3a. Since some branches are greater than A, the Pow-R-Line 3a must be used. Step 3 Select and use the IER chart corresponding to the panelboard chosen. (Figure 5) First, go to the left most column and select the Voltage Level- for this example: 600Y/347V (A). Next, select the Fault Level associated with that voltage from the Fault Level Available column. Use the next highest value if the exact level is not shown - for example: 40kA - go to 50kA (B). Now, select the Main or Upstream Breaker Type Amperage. Proceed horizontally to the column with the required ampere rating of upstream device - 400A (C). Finally, proceed vertically down from this amperage (C), and horizontally across from the fault level (B). Where these intersect, (D), read the required upstream device, -. Note: If no main or upstream breaker or fuse is shown, then go to a higher fault level that shows a device protecting the particular branch. If one is not shown, then a good combination does not exist. The upstream device selected is a 3400 breaker with standard rated FDB 14kA branch breaker. That's INTEGRATED EQUIPMENT RATINGS!
