I was informed this morning that all of our electrical panels for HVAC equipment are required to have the SCCR rating as of April 25 2006. They are going to have a web seminar on it on May 17. This is required for all UL508A listed panels which accounts for 99% of the panels we build.
We use mostly fuses which jumps up the rating, but keeping track of which device trumps the other and how to make sure everything is kept straight over a thousand components is going to be one heck of a learning curve.
