Own home - Low voltage lighting,, using GE RR relays. After 45 years the class II 24 Vac transformer finally failed, internally shorted.
45 years ago power electronics just about did not exist, now one can get a 85V-265Vac to 24 Vdc converter for $10 !
Can set current limit to less than 1/2 amp on the unit to comply with class II, etc.
Question is: Is the use of one of these NEC compliant? It is UL listed.
I tend to interpret NEC to my own advantage (or ignore it altogether in some cases), but wondering how others would interpret this use. Standard cord plug-in, 24V output on external screw terminals.
