Get that right and everything works as expected. But, if current, frequency, or operating temperature is not properly accounted for, then busbars and components can overheat. Field failures are expensive in terms of money, reputation, and the prospects for future projects.<\/p>\n<p>For <a href=\"https:\/\/www.schneider-electric.com\/en\/work\/campaign\/innovation\/power-distribution.jsp\">power distribution systems\u00a0<\/a>designed for any voltage, be sure to:<\/p>\n<ul>\n<li>Adhere to the recommendations of <a href=\"https:\/\/webstore.iec.ch\/publication\/5457\">IEC 61439\u00a0<\/a>or the appropriate local standard.<\/li>\n<li>Follow the installation guidelines and recommendations provided by all the original manufacturers when it comes to derating, assembly and more. This may mean that several manufacturers\u2019 instructions must be accounted for. If using a unique manufacturer\u2019s pre-fabricated solution, this is already taken care of.<\/li>\n<li>Use the right type of copper or aluminum.<\/li>\n<\/ul>\n<p>Regarding the <strong>first point<\/strong>, IEC 61439 provides rules needed to ensure the quality and safety of the switchboard as well as how to test it. For instance, it specifies how big a conductor must be to safely handle a given amount of current under stated operating and environmental conditions.<\/p>\n<p>However, as the <strong>second item\u00a0<\/strong>above notes, manufacturers often provide additional information about how to assemble devices in a switchboard and how to derate them for environmental and operational circumstances. If manufacturer instructions are available, follow them. At times products and solutions from several manufacturers are involved, and so all the recommendations \u2013 which could conflict \u2013 should be adhered to. Alternatively, if using a pre-fabricated solution, then following guidelines and recommendations is already taken care of.<\/p>\n<p>Finally, the <strong>third point\u00a0<\/strong>is important because the quality of the conductor determines overall system quality.<\/p>\n<p>Copper should be Cu-ETP H12 or the equivalent. It has the required conductivity, which means that busbars will not get too hot. It also has the needed malleability and mechanical properties, which means that it can be bent, drilled and cut without a problem. For similar reasons, aluminum should be a grade with between 55 and 61 percent conductivity as defined by the <a href=\"https:\/\/en.wikipedia.org\/wiki\/International_Annealed_Copper_Standard\">International Annealed Copper Standard<\/a>. Thus, it should be grade 1350 or 6101, as specified by the ASTM B609 or ASTM B317 standard, respectively. It also must have the right surface treatment and not be raw aluminum so that conductivity is retained for a long time.<\/p>\n<p>Details about how this can be applied to specific amperage ranges can be found in the up to 630A and up to 3200A articles.<\/p>\n<p>For more information, visit our <a href=\"http:\/\/www.schneider-electric.com\/b2b\/en\/products\/product-launch\/prisma\/\">low-voltage switchboard solutions page<\/a> and download our free <a href=\"https:\/\/www.schneider-electric.com\/tools\/registration\/promo\/us\/en\/getpromo\/70275P\">eGuide<\/a>.
