I have an Intermatic T30004R Timer that is not being used by anything currently. I was made aware via this forum that I should have my SWG connected to a timer. I just wanted to make sure that I am doing this correctly. In reading some information online, I am understanding that I am going to pull the 2 black wires coming from the SWG from the breaker and run them post 2 and 4 on the timer. Then I am going to connect 2 new wires from post 1 and 3 into the breaker. Is this the correct wiring? Is there anything else I need to know or do? Also I am curious about the ground wire coming from the SWG. Its currently in the ground bar at the bottom of the photo. Do I need to run a ground to the timer as well?
