I’ve seen some paperwork on something similar. It was tested with #14 wire, which of course no one uses which makes it void.
Also who is now legally responsible if there is an issue? I heard of a big US distributor who had a similar report done. 14 gauge wire. After the fire, and all the lawyers the report/ certificate was worthless, which put the legal responsibility back on the distributor. What I don’t understand is that connectors are about the cheapest part of the install. Just use like for like and eliminate most issues and also any liability. ( see latest Walmart/ Tesla fiasco, grab some popcorn gonna be good) I’ve rarely seen like for like failures but many dissimilar ones. PV Cables has them all, even the really weird ones. Info I’ve seen from MC says that different OEMS use different coatings which don’t always agree and can cause accelerated corrosion. Actual sizes of the plastic and metal and tolerances can be off creating issues. Just not worth it in my view.
