I'm installing under cabinet low voltage "puck" type lights in my kitchen.
My question is on the transformer and related installation. I realize the total output wattage of the transformer should be greater than the total accumulated wattage of the lights. But as far as installation is concerned, what is the proper way to install the transformer? I live in a NYC suburb, where b/x (armored cable) is code. I'll run the b/x from a J-box to the transformer, and then low voltage wire from the transformer to the 1st light, and then daisy chain the wire from light to light.
Does the transformer need to be mounted in a box? Or on a sheet metal backer? I presume I need to keep the transformer accessible for possible replacement later on, but my concern is I just don't want the transformer sitting on top of insulation somewhere in a corner of the attic as this may pose a hazard.
Anyone have any ideas or guidance with this?
