While creating some new part numbers in our company's PLM system, I noticed that the terminal block bridges were neither UL-listed nor recognized.

I then checked a few other ones from other manufacturers. Same thing.

Do terminal block bridges not require UL listing? Are they simply considered Bus Bars and fall under 29.2.2 of the UL508a standard?
