So after asking around here I was told that it is OK to run a ground wire from an existing near by power outlet (on a different circuit) to a new power outlet. The layout is below. The garage circuit(to the left) is something that I extended to that end of the garage using PVC conduit.

What is a recommended way to run that wire, given the below layout?

Update: here are is the type of wire that was used by the previous owner AND a close up of the point where the cable enters the wall to feed the first light and then it exits to go up and head over to the second light. I rotated the image so you can read the wire specs, in fact the right side is the bottom of the image

My intention is to install a power outlet just below that hole I might want to add a switch to shut off the lights when the in house switch is on so I can work with the table saw without having the lights on during the day time.

Update: Here is a picture of the box behind the first light (the one to the left). The black (hot) wire seems to have a cracked insulation just where it exits the wall, I had to put some tape there enter image description here

  • I have not asked about how to run that wire anywhere, I need to know if I need to use conduit, to cover it in some way if there are any norms or regulations dictating how to do this

  • Ex: do I run the wire from the case of the outlet that is already there (will look ugly) or could I branch the wire at the elbow level up above that power outlet?

  • I have added a picture showing the wires and the hole in the wall allows the cable to reach the first light. See the Update section of my post

As per this question: https://diy.stackexchange.com/a/185137?noredirect=1 I do not need to run a ground wire as my wire already has a ground.

  • Have you looked at the insides of the boxes involved to verify that a ground wire is present? Your NMD-90 may predate the requirement for a ground wire... Commented Feb 20, 2020 at 2:52
  • Right now is bitter cold (and dark) around here, probably I will try to have a look tomorrow. I don't know if there are any boxes on the garage light circuit. If there are any they must be covered by ceiling and I have no access to them. I posted about the next step here diy.stackexchange.com/questions/185139/… BTW everything in the house seems to be wired with grounding

  • I just updated the question with a picture taken today, I almost lost my fingers with this cold and the metal of the light was even colder. Plus that I had to tape the hot wire which has the insulation cracked
