Gym Project: Electrical Part 2

The main goal of the Gym Project is to hang a 32" TV in the home gym. The TV will hang where previously there was a mirror. There was no drywall behind the mirror, only framing. So, I had to hang some drywall. Now that the drywall is done I can do some more electrical work.

Again, only have a professional do your electrical work. I am a certified low voltage contractor, not high voltage. The purpose of this blog is not to confirm nor deny the use of a certified electrician.
After the breaker is off and it is confirmed the wires are not hot, the outlet was wired in.
The low voltage cable and speaker wire will run to my wiring closet. When I built the house I ran all of the computer Ethernet cables, coax TV cables, telephone cables, and speaker wire to a single central closet. In this closet I put a 19" rack and various patch panels. Everything was neat until the cable TV company showed up one day and did a hatchet job on the coax TV cables. You'll see a picture of that mess which I need to clean up someday.
I ran the cables through the drop ceiling.
Three important things to know about low voltage cabling: first, keep it away from the high voltage runs. Even with shielding you could pick up interference. Second, when attaching the cable to studs and beams, the attachment device should leave no impact to the jacket casing. In my case I am using a staple gun and sometimes the staples can be so tight that it cinches and indents the cable. If that happens then the cable's properties change and could result is greater resistance or other problems that will impact quality. Don't get the cable hangers too tight.
Finally, third, label both ends of the cable.  I use a numbering scheme that I relate to a floor plan of the house that hangs in the cabling closet.

With the cable ran, it is a matter of terminating the ends.
I have some testers for some cables to make sure I gave a good termination. I don't have a tester for Cable TV coax, so, no testing today.
The last step is to attach it into the Cable TV network.

Check back for more updates as I continue the Gym Project.
