I know that these low voltage (LV) hockey puck light fixtures have been around for awile. I also know that the wiring of them have been argued about too. My question is, does the splice where the NM wire attaches to the flying lead of the LV light have to be accesible? Is there a code section that says yes? or no? How many times have you seen where the splice is made, then tucked back into the wall, and then have the wall sealed with either grout or a silicone. Then if/when you have to go and change lights later on, you have to cut open the wall to remove the splice. (Or maybe they don't remove the old splice, but just add a new splice on the outside.) Any comments?
