Hi there, First post here. Relatively new DIYer so trying to learn a lot on many things. I'm trying to run an electrical line to feed the outdoor motion sensing floodlight with a switch. Have a couple of questions whether existing line run is correct and also what the right way to run the new line would be. Here are some pic's: Pic #1: Existing line to floodlight 1. To outside floodlight 2. Existing line stapled Q: Is this the right way to run the line downward at this location? 3. The new line I am adding (behind the ceiling joist) Pic #2: New line When I run this new line behind the ceiling joist, it needs to make a turn here. 1. New line (stapled behind ceiling joist). Q. Is it ok to run the new line just below the joist in making this turn and then just run along the top edge of the top plate after the turn? OR 2. Q. Is it better to drill a whole thru' the ceiling joist at this spot, then try to staple the line on top of the top plate so that it's clear of the side of the top plate? Pic #3: New line - electrical switch Here the line is making another turn downward -- to the electrical switch. 1. Q. I wonder if this is acceptable way when making the turn? (I have not stapled the line yet) Or should I drill a hole thru' the top plates to make the downward turn? 2. Other existing wires The other wires are all stapled along the top plates now. You can see how all the other existing lines run downward . They were like that when I moved into this house. Q. Is this acceptable way of running the wires? Q. If not, what'd be the right way of for all these other wires? Another reason I am asking is that I am thinking about installing a ceiling and putting dry walls in the garage. I wonder if all these wires would need to be fixed up (and which way) before I can install the dry walls and the ceiling. Which would lead to a separate question of how to install dry wall in this garage. Let me know if I need to post a separate thread on ceiling/drywall install questions... . PS: This is a 2-car garage. There are only two 5" size ceiling joists 8 feet apart that run across the two garage walls.
