Temporary Cabling Deployment FAQ

Scope & Application

1. What Is a Temporary Cabling Site?

A temporary cabling site is any location where cables are deployed for short-term use—typically under 90 days—and must support full teardown, reroute, override, and removal without damaging the structure or violating code. These sites require teardown-ready cable systems with inspection access, override logic, and full compliance with NEC, OSHA, and AHJ standards. Cabling must be labeled, mountable without permanent anchors, and removable without structural impact.

2. Where Are Temporary Cabling Sites Found?

Power Systems

3. What Cable Types Are Approved for Temporary Power?

Temporary power systems must use flexible, teardown-ready cables rated for the environment and load.

• SOOW and SJOOW: Used for outdoor and indoor temporary power. Rated for oil, water, and abrasion resistance.

5. What Labeling and Teardown Protocols Apply to Temporary Power?

All power runs must be traceable, override-ready, and removable without damage or confusion.

• Source/Destination Labeling: Each run must be labeled at both ends for teardown and reroute.
• Override Tags: Used to flag alternate circuits or emergency reroutes.
• Service Loop Logic: Loops must be sized for retermination and labeled for reuse.

6. What Grounding and Surge Protection Is Required for Temporary Power?

Temporary power systems must meet NEC Article 250 grounding rules and include surge protection for sensitive gear.

15. What Are the Risks of Cable Tray Misuse in Datacom Zones?

Improper use of cable trays can lead to overheating, signal degradation, and AHJ violations.

• Overheating: Stacked bundles restrict airflow and increase fire risk.
• Arc-Flash Risk: Mixing voltage classes in shared trays violates NEC separation rules.

19. Can Low-Voltage Cables Share Trays with Datacom or Power?

No—low-voltage cables must be separated by signal type and voltage class. Shared trays violate NEC and AHJ separation rules.

• Signal Separation: Low-voltage must be routed separately from datacom and power to prevent interference.
• Tray Labeling: Each tray must be labeled by signal type and teardown zone.
• AHJ Enforcement: Shared trays may trigger inspection failures and forced reroutes.

AV Systems

26. Can AV Cables Be Suspended from Truss or Battens?

Yes—AV cables may be suspended from truss, battens, or pipe grid using load-rated clamps, hooks, or mousing ties. All suspended runs must be labeled, teardown-ready, and approved by the AHJ or venue authority.

• Load-Rated Hardware: Use only clamps, carabiners, or cable hangers rated for the cable weight and environment.
• Strain Relief: Cables must be supported at intervals to prevent sag, tension, or jacket damage.
• Teardown Access: All suspended runs must be reachable for safe removal without ladders or lifts where possible.
