the building was a small two story, stick frame single family home built in the early 50's...in the early 70's it was converted to a tavern with a small dining area...the new owner will now feature live music in what was the dining area...he is now planning to add a drop ceiling for better sound purposes...we will be adding, replacing and relocating 20 +/- existing ceiling pendant lights to recessed in the drop ceiling...all of the existing lights are wired in romex...very few (if any) of the existing light JB's can be moved...(Ques #1) is it legal for me to add romex jumpers to the the new light locations??...if not i will use MC jumpers...(Ques #2) is it legal to have the existing romex in the same JB as the new MC jumpers??
