The 2026 National Electrical Code is ready for publication.
The scope of Chapter 8 is changed from all building communication system
installations, to only communications wiring outside or at the cable
entrance point.
Data/Communication system wiring is now in Chapter 7, which means it will
be covered by general NEC requirements. For those designing data centers
after 2026, many data/communication installation "best practices" will
become code requirements.
Probably the biggest change will "working clearances" for communications
equipment in wiring closets and cabinet door openings in data centers.
No more cramming equipment into shared closets or draping cables across
the room. After the 2026 NEC is adopted, building code officials will be
able to enforce those requirements.
