Codes, Bonding and Grounding for Communications (NEC)
The code side of low-voltage work, followed through Cobalt Line Systems' Austin closeout crew on a riser retrofit, a school, a hospital wing and a condo tower: how the NEC, the building code and the TIA standards apply, NEC Chapters 7 and 8, cable listings and substitution, plenum, riser and general spaces, separation from power, entrance protectors and outside plant, optical fiber rules, rated walls and floors and tested firestop systems, bonding and grounding, the TIA-607 bonding backbone, and a full code and bonding inspection.

What you'll learn
- Explain how the NEC, the building code, product standards, cabling standards and specifications govern low-voltage work in Texas, and who enforces them
- Identify which parts of NEC Chapters 7 and 8 apply to communications, Class 2, Class 3 and optical fiber installations
- Read cable legends and apply the fire rating hierarchy and substitution rules to choose and check cables
- Classify plenum, riser and general spaces and determine the minimum cable rating for every segment of a run
- Apply separation, barrier and support rules between low-voltage and power wiring and within shared pathways
- Install and check entrance protectors, bonding conductors, outdoor cable lengths and outside plant pathways
- Apply the rules for nonconductive, conductive and composite optical cables, innerduct and abandoned fiber
- Recognize rated walls and floors and state the firestop ratings each penetration requires
- Select, install, label and record tested firestop systems within their fill and annular space limits
- Explain grounding and bonding, why all systems bond to one grounding system, and why bonding conductors are kept short
- Lay out and size a TIA-607 bonding system with PBB, TBC, TBB, SBB and BBC, and test it
- Plan and carry out a code and bonding inspection, correct deficiencies and hand over complete records
