Inspecting GFCI and AFCI Protection - InterNACHI
Learn how to inspect GFCIs and AFCIs for home inspection according to the 2015 International Residential Code. Find out the definitions, functions, requirements and test methods of these devices that protect against electrical hazards.
Los interruptores de circuito por falla de arco (AFCI)
Los AFCI son dispositivos que detectan y previenen los arcos eléctricos peligrosos en el cableado de bifurcación en las casas. Aprenda qué es un arco, cómo los AFCI funcionan y en qué ubicaciones son obligatorios según los códigos del edificio.
AFCI Testers - InterNACHI
Learn what AFCI testers or indicators are, how they work, and why they are important for inspecting AFCI-protected receptacles. Find out the limitations and effectiveness of AFCI indicators and how they differ from GFCI indicators.
Arc-Fault Circuit Interrupters (AFCIs) - InterNACHI
Learn what AFCIs are, how they work, and where they are required by code. AFCIs are special devices that detect and respond to dangerous electrical arcs in home branch wiring and prevent fires.
Ground-Fault Circuit Interrupters (GFCIs) - InterNACHI
Learn about ground-fault circuit interrupters (GFCIs), devices that protect against electric shock by detecting and disconnecting unbalanced current. Find out the three types of GFCIs (receptacle, portable and circuit breaker) and the NEC rules for their installation.
Learn about the primary components of the electrical system in your home, such as service entry, service panel, and branch circuits. The first point of disconnect for the conductors from the utility company is at the main panel, also known as the service panel or panelboard.

Electrical Inspection Guide Part 2 - InterNACHI House of Horrors
This is a significant change, and kitchens will now become somewhat of a “puzzle” since both GFCI and AFCI protection is required. If I were to wire a kitchen according to the 2014 NEC, I would probably accomplish this via a GFCI-protected subpanel (specifically dedicated to the kitchen), and use AFCI circuit breakers to feed the kitchen.
19. Correct breaker types should be used for each panelboard, according to the manufacturer’s label. 20. Each circuit should be clearly and specifically identified as to its purpose. No two circuits should be labeled the same. No circuit should be identified in a way that may be subject to change with occupancy.
