An inspector red flagged a job today because he said the can lights we used were not "leak rated". I asked him if he was talking about IC/ NON-IC lights and he said no, it had to do with an "energy code". Does anyone know what a "leak rating" is? He also said that he thought the lights had to be 6" from any combustable material and he would have to get back with me on that one, but 410.66(A)(1) & (2) require 1/2" for non IC type and no clearence for IC type. Is there something in the energy code that states otherwise? Thank-you.
