In some instances I have suggested just getting those conductors out of that box and making the splice to an older circuit back in a switch prior to the Luminaire's box, this is consistent with getting all the cloth or 60C wire out of an outlet where a 90c termination is required. Does anyone else feel this is a viable solution in smaller scopes of work. (I generally encourage electricians to consider discussing replacing older circuits fully, with an "HO" if there are issues as such with adding load or re-energizing older conductors in the name of safety.)
