Class II is a type of construction - not necessarily relevant to this thread ? Class 2 is a North American code stuff (similar to an LPS).

Some standards do not use the acronym and do not show up in a “SELV” search. Do a search for “safety extra-low voltage” and you get even more! Did not try expanding out the other acronyms.

There are many definitions of SELV and PELV. It would seem that every TC has its own definitions. Just 5 for FELV and they are consistent. Also, check out ELV (which makes the FELV inconsistent).
