Bonus Tip
Verify Local Amendments Before Installation
Always cross-check 2026 NEC with state/local codes, as 45% of jurisdictions amend GFCI/AFCI rules (e.g., California requires extras in pools). Download free NFPA viewer for $0 and consult AHJ early to avoid $1,000+ rework. Schedule inspections within 7 days of rough-in for 90% pass rates.
