Buyer information, not installation instructions. Requirements depend on the adopted local code and exact product. Electrical work and site diagnosis should be performed by qualified professionals.
When a project calls for GFCI and AFCI protection, check both functions in the specification. A device marked GFCI does not automatically provide AFCI protection, and vice versa.
What a GFCI does
A ground-fault circuit interrupter (GFCI) shuts off power when it detects a ground fault, helping protect people from electric shock. A conventional circuit breaker’s overload protection serves a different purpose. [Source]
What an AFCI does
An arc-fault circuit interrupter (AFCI) addresses the fire risk from dangerous electrical arcing. CPSC explains the distinction between this function and GFCI shock protection. Some devices include both; check the product’s designation to see which functions it provides. [Source]
What to put in the purchasing brief
A qualified electrical professional should determine which protection the circuit and location need under the locally adopted code. Do not make that decision from a product category name or work inside an electrical panel yourself.
Once those requirements are clear, give the supplier the protection type, voltage, current rating, receptacle configuration and installation environment.
Compare the exact FAHINT model
Compare GF15 and GF20 for standard-face 15A and 20A GFCI outlets. Read the exact model’s specifications and listing documents, then confirm indicator behavior, test instructions and finishes. GFCI identification does not establish AFCI protection.
