This is in my garage. I am trying to add a second circuit in order to be able to run the dust collector and the table saw at the same time. I did run them on the existing circuit with no load and the breaker did not trip but I want o be on the safe side.
There is one circuit that enters the garage right where you see the GFI power outlet. I extended that to a workbench that I have to the left of the door on the left side (conduit not shown) and to the right to feed the garage door lift and to add one more power outlet also connected with a wire run through plastic conduit. This circuit is grounded.
Now I have wiring coming into the garage from the porch then it is run as seen down to the bottom level of the first garage front light. The cable goes into the wall outside to feed that light bulb and then it comes back it goes above the garage door opening and it lands on the other side of the garage door (not pictured) to feed the other garage door light (extreme right of the picture) The above are on a 15A circuit that has a on/off switch in the house.
Can I run a ground wire from the power outlet that is next to the new power outlet that I want to add (highlighted in blue)?
..all my regular circuits are 15A ..
