Welcome to the Schneider Electric NEC 409/UL 508A Support Web Site

Schneider Electric has created this web site to help customers understand the significant impact the changes in the 2005 National Electrical Code (NEC) and Underwriters Laboratories (UL) product standards will have on their business. Whether you are an Industrial Control Manufacturer, Panel or Machine Builder or an individual business looking to modify existing panels, the code and standards changes may affect your installation.

A number of educational and product search tools are available to you on this site. You can select from overview information, UL 508A Short Circuit Current Rating (SCCR) determination flow chart or information on our individual or combination product SCCR’s. Use the listing at the left to select your option.
