GFCI and AFCI protection wrapper

Why you care (60 seconds)​

GFCI and AFCI requirements are among the most common inspection findings. Confusing the two protections can leave people at risk or fail an exam question.

Where people lose time​

  • Mixing up which locations need which protection.
  • Assuming a device type covers every downstream outlet without verification.
  • Skipping manufacturer instructions on line and load terminals.

This is​

The rule in plain language​

Provide personnel protection against shock (GFCI) and protection against arc faults (AFCI) when the code requires it for a circuit or location.

When it applies​

For specific locations, circuit types, and occupancies where GFCI or AFCI is mandated by the code.

What you must do (checklist)​

  • Identify the location and circuit type for each outlet or device.
  • Determine whether GFCI, AFCI, or both are required.
  • Choose protection type (breaker or device) that covers the full circuit.
  • Follow listing instructions for line and load connections.
  • Test and label devices after installation.

Quick examples​

  • A receptacle near a wet location often requires GFCI protection.
  • Some living area circuits require AFCI protection at the breaker.
  • Dual-function devices may be needed when both protections apply.

This is not​

Common misreads​

  • Treating GFCI and AFCI as interchangeable.
  • Assuming the first device in a run always protects the rest.

What it doesn't cover​

  • Surge protective device requirements.
  • Specialty equipment with unique protection rules.

False friends​

  • Confusing equipment grounding with GFCI protection.

Exceptions & edge cases​

  • Some equipment types have listed exceptions or alternate methods.
  • Nuisance tripping may indicate wiring issues rather than device failure.

Cross-references (NEC map)​

  • Primary: 210.8, 210.12
  • Secondary: 110.3(B)

Exam traps​

  • Picking the wrong protection for a location-based question.
  • Missing cases where both GFCI and AFCI are required.

Field notes​

  • Keep a test log for GFCI and AFCI devices after commissioning.
  • Label protected outlets if downstream protection is used.
