That’s correct for the most part, but You also have to assume the first connector and last connector could see full line to line voltage under a fault condition. In terms of would it work, I think you’re correct. But something like that would never see UL certification.
I’d have to look, but I have always assumed that 300v was the limit of any connector that style. I’m pretty sure I seen it in one of the bridgelux documents too. I’m always of the idea when I give someone advice through here I prefer to account for stuff like that. Just like parallel connected leds on a cv driver. Just because I would do it, doesn’t always mean I would suggest others do.
