Cabling Rough In by Electrician, Infotel terminates cable ends

You have sold this job and we are your sub contractor. You are responsible for all cable locations. We have a few requirements.

Colors and Lables

We don’t need for you to label the cable numbers.

We do like different color cables as follows

  • Blue = data
  • White = voice
  • Red or Yellow = security cameras

Cable finish at the device jack

  • 12” of cable out of any single gang box for devices such as a phone or computer
  • 12” out of a hole for a ceiling wifi device or security camera.

Cable finish at the patch panel

12  feet of cable beyond the centralized frame location for the Ethernet switch. If the cable bundle drops from the ceiling, take it to the floor and go 4 feet more.
