- NEC 2023 vs 2026: The Changes That Affect Everyday Work
NEC 2026 was published in August 2025 and adoption has barely begun. For most jobs the live comparison is 2020 vs 2023 - and one 2023 change actually requires less than 2020 did.
- Where GFCI Protection Is Required (NEC 210.8, With the 2023 Changes)
A GFCI trips at 4–6 mA; a 20 A breaker needs 20,000 mA. Here's every location 210.8 covers - and an honest account of which recent expansions your jurisdiction may have amended out.
