Verified 2026-10-25 Confidence: High

Clause 9.3.1.1 of ANSI/TIA-569-E (2019) takes its mandatory separation between telecommunications cabling and power branch circuits from NFPA 70 (2017), permits zero separation when either cable set runs in a continuous, fully enclosing, bonded metallic pathway of sufficient wall thickness, and requires none at right-angle crossings.
