Brady Offers Solutions for Short Circuit Current Rating
There has been a significant increase in the misapplication of control panel products that brings into question the safety of those installing and using this equipment. Article 409 impacts control panel equipment design and construction so that the entire panel and all its components inside meet a defined Short Circuit Current Rating (SCCR) and that the panel is appropriately labeled with the SCCR. Before now, industrial control panels could have been installed based upon general electrical requirements from several different articles in the NEC. Previous standards allowed the practice of listing a panel according to the AIR rating of its main over-current protective device. The new standards include the entire combined power circuit in requirements for the SCCR.
