Looks up whether a dwelling-unit branch circuit serving a given room or area typically requires AFCI protection (NEC 210.12(A)) and/or GFCI protection (NEC 210.8(A)), based on the commonly enumerated location lists most recent NEC cycles use. This is a code-reference lookup, not a calculation — it's meant as a quick planning check, not a final code-compliance ruling.
Standards followed
NEC 210.12(A) — arc-fault circuit-interrupter (AFCI) protection, dwelling unitsNEC 210.8(A) — ground-fault circuit-interrupter (GFCI) protection, dwelling units
What it can do
- Per-location AFCI and GFCI requirement lookup with the specific citation.
- Flags locations where the requirement depends on additional context (e.g. proximity to a sink, or isn't explicitly enumerated) as "verify locally" rather than guessing.
Example problem
Kitchen branch circuit.
- 210.12(A) lists kitchens — AFCI required.
- 210.8(A)(6) requires GFCI on all 125-250V, 15/20A kitchen receptacles (not just countertop, since the 2020 NEC cycle) — GFCI required.
Both AFCI and GFCI required — many installations use a dual-function AFCI/GFCI breaker here.
These enumerated lists change between NEC editions (GFCI coverage for laundry areas and all kitchen receptacles was added in the 2020 cycle, for example) and many jurisdictions apply local amendments. Always confirm against the specific NEC edition and any local amendments adopted by the AHJ before finalizing a design.
