What it is
A construction specification document for a Johnson County Iowa shower house project that references NFPA 70 National Electrical Code and specifically mentions NEC 110.26 working clearances in relation to sprinkler protection allowances.
Why it matters
NEC 110.26 working clearance requirements frequently create spatial conflicts with fire protection systems during design and inspection. Electrical contractors and MEP coordinators must resolve these overlaps early to avoid field rework or AHJ delays in public facility projects.
