1 4DB01R0/1 0/01 Data Bulletin Replaces 4DB01R9/04 Square D Load Center Sht-Circuit Current Ratings Retain f future use. Introduction Fully-Rated System Series-Rated System Two-Tier Series Rating This document defines fully-rated systems, two-tier series sht circuit current protection and three-tier series sht circuit current protection. It also addresses NEC requirements and illustrates series rating labels currently provided with Square D multi-metering and load center equipment manufactured by Schneider Electric. The location of series rating labels applied to Square D load centers is depicted on pages and of this document. In a fully rated system, the interrupting rating of all the overcurrent protective devices must be greater than equal to the available fault current at the line side terminals of each device. The NEC and UL permit assigning a sht circuit current rating to a tested combination of circuit breakers fuses that is higher than the individual rating of the downstream overcurrent protective device. Testing by the circuit breaker manufacturer demonstrates that the combination can safely interrupt the available fault current. NEMA defines a series rating as follows: Series Rating A sht-circuit interrupting rating assigned to a combination of two me overcurrent protective devices which are connected in a series and in which the rating of the downstream device(s) in the combination is less than the series rating. The combination of overcurrent protective devices may be enclosed in a single piece of equipment such as a load center. Three-tier series rated systems are most commonly designed with the supply side device in a separate enclosure, such as metering equipment, that feeds a load center. NOTE: The load-side device is always a circuit breaker. The supply-side device may be either a circuit breaker a set of current-limiting fuses. A two-tier series rating can be used within a single enclosure (Example 1) in separate enclosures (Example ).

2 Square D Load Center Sht-Circuit Current Ratings 4DB01R0/1 Data Bulletin 0/01 Location of Two-Tier Series Ratings Label in Schneider Electric Equipment Figure 1: Two-Tier Series Ratings Label Application The permitted NEC and UL series ratings are found marked in the equipment. Unless the equipment is marked, one cannot be assured the circuit breaker combination will perfm appropriately in the enclosure. Schneider Electric marks two-tier series ratings on the inside wall of load centers (See Figure 1). The two-tier series rating labels applied to current production convertible main QO and fixed main Homeline load centers are depicted in Figures and 5, respectively. NOTE: The infmation contained in this data bulletin is current at time of printing; however, ratings may change additional ratings may be added without notice. Refer to the series-connected ratings marked on the equipment. Two-tier series rating labels are applied to the side wall of current production QO and Homeline load centers.

7 4DB01R0/1 Square D Load Center Sht-Circuit Current Ratings 0/01 Data Bulletin NEC Requirements Figure 7: Example of Label Provided Two sections of the NEC address markings of series ratings: Section 110. and Section 40.86(b). Per Section 110., the equipment must be legibly marked in the field to indicate the equipment has been applied with a series combination rating. The intent of this section is to alert the installer that the circuit breakers were installed based on a series rating, and to mark the equipment with the sht circuit current rating being applied in the series combination. Schneider Electric provides a label f this purpose with all MP Meter-Pak Meter Centers and EZ Meter-Pak Meter Center Devices. The label is not applied by Schneider Electric, but is provided loose in these devices f application when series ratings are applied by the installer. SERIES COMBINATION SYSTEM RATED AMPERES. IDENTIFIED REPLACEMENT COMPONENTS REQUIRED. Additional replacement circuit breakers must be manufactured by Square D and have a sht circuit current rating equal to greater than that of the circuit breaker(s) presently installed. Refer to additional infmation provided with this equipment. Failure to do so can result in electrical explosion and fire. CAUTION / PRECAUCION SISTEMA COMBINADO EN SERIE CORRIENTE NOMINAL: A ES NECESARIO IDENTIFICAR EL COMPONENTE DE REPUESTO Los interruptes automáticos adicionales o de repuesto deben ser productos de Square D; su criente nominal de ctocircuito debe ser igual que o may que la de los interruptes automáticos actualmente instalados. Consulte la infmación adicional incluida con el equipo. El incumplimiento de esta instrucción puede causar una explosión eléctrica e incendio. Section 40.86(b) requires that the series combination of overcurrent protective devices be tested and marked on the end use equipment. This marking is applied by the manufacturers of switchboards, panelboards, load centers, etc. Schneider Electric marks load center enclosures and covers with series ratings per Figures 1 and. A series rated system is an affdable, viable alternative to a fully rated system. Series ratings can be two-tiered multi-tiered, depending on the levels of overcurrent protection tested and certified. Series ratings include circuit breaker/circuit breaker combinations and also fuse/circuit breaker combinations, but the furthest load side overcurrent protective device is always a circuit breaker. Overcurrent protective device combinations used in series rated systems should be marked on the end use equipment by the electrical distribution product manufacturer. Equipment installed as part of a series rated system must be marked in the field to indicate the sht circuit current rating being applied in the series combination Schneider Electric All Rights Reserved 7
