Had an old ceiling light socket in an un-finished basement that had used a pull chain (before it broke). Recently replaced it with a new plain socket, but there is nothing to turn it on and off except unscrewing the bulb. I'd like to add a single pole switch nearby (no more than 10ft or so).
My plan would be to run a single line from the light box, parallel with the floor joists, in flexible conduit, up, over and down to a switch box on a 4x4 post. There is nothing else running to/through the light box as of now, so I'd simply hook it up as shown.
(red being neutral...and the ends would be marked to indicate they are acting as hot)
There wasn't a ground running to the light box, on the old socket, or on the new socket as far as I could tell, would that be a problem at all?
I'm assuming that just leave the wire exposed, without some kind of conduit would be a no no if it's extending down below the joists, correct?
If I wanted to add an outlet at some point, running from the light box, would I simply tie it in to the hot and ground running to the box? And if I added an outlet, would it be a problem not having a ground? (I might just be able to detach the source wire and strip the ground back if there is enough slack)
