I've got a 20x20 garage with the usual single incandescent bulb. I already pulled that and put in an 8' flourescent but I want to put in 3 more around the perimeter. Is it possible/safe/legal to split the line coming into that box into 4 feeds or do I need to run them from point to point? I'm assuming the answer is point to point but want to check with the folks in the know.
