Exactly. When I talked to UL, the gal I talked to at their Camas, Washington HQ told me that they would not undertake designing new tests and procedures if they did not think the product was new and innovative. Not her exact words but look up one of my posts from last week that didn't get deleted for a more precise quote. She added that if their engineers decided it wasn't viable, UL would not waste their time and the clients money chasing after it. Not my opinion- UL's. But don't listen to me, I'm just a old country boy and don't know nothin!!!
