The SnapNrack UL 2703 document highlights it's UL listing when used with Type 1 and Type 2 modules.
https://snapnrack.com/wp-content/uploads/2019/05/SnapNrack_Fire_Classification_Tech_Bulletin_v.2-1.pdf *SnapNrack Series 100, Ultra Rail and RL systems have been Certified for a Class A fire rating with Type 1 and Type 2 modules, in accordance with the standards set forth in UL1703/2703 and IBC 2012.* The Mission Spec sheet references that it is UL listed under 1703. https://s3.amazonaws.com/ecodirect_docs/Mission-Solar/Mission-Solar-MSE320SR8T-datasheet.pdf For further reference this 1703 document talks a little about the different module "types" that are tested. https://www.intertek.com/building/standards/ul-1703/ *The “Type” of module dictates the number of fire tests that will be required during the test process, there are 3 common types (15 total) that are determined by their superstrate, encapsulant, substrate materials, and size of module.* Sam Haraldson <s...@onsiteenergyinc.com> Installation & Service Manager <http://www.onsiteenergyinc.com/> | o.
