Study Notes
GFCI and Receptacle Requirements
- Class A GFCI devices trip at ground-faults between 4 to 6 milliamperes.
- NEC 406.4(D)(4) mandates AFCI protection during receptacle replacements when specified by the Code.
- GFCI protection is necessary for receptacles located within 6 feet of wet-bar sinks.
Replacement and Protection Guidelines
- An existing two-wire, non-grounding receptacle can be replaced by a GFCI-type receptacle when required by Code.
- GFCI protection is exempt for receptacles placed behind ranges or refrigerators.
- An "outlet" is defined as a point in the wiring system where current is drawn to supply equipment.
Appliance Connections Management
- Single or duplex receptacles in fixed, dedicated spaces for appliances do not require tamper-resistant designs.
- GFCI for personnel protection activates upon detecting a current imbalance of 4 to 6 mA.
Fault Types and Required Protections
- Series arcing faults occur when a current-carrying conductor breaks or has a loose connection.
- Outlet protection classification:
- GFCI: Bathroom and garage receptacles, kitchen counter receptacles, unfinished basement outlets.
- AFCI: Bedroom and hallway lighting outlets.
- No protection: Kitchen lighting outlets.
Historical Context and Types of GFCIs
- IDCIs and ALCIs were introduced in older homes lacking GFCI protection, offering shock safety.
- GFCI construction types include circuit breakers and receptacles.
System Interactions and Testing Protocols
- GFCI breakers protecting fire and smoke alarms may cause nuisance tripping, rendering alarms inoperative.
- UL standards require GFCIs to have marked instructions and mandates monthly testing, plus checks after severe storms.
Home Office Regulations
- Conversion of a bedroom to a home office typically triggers an AFCI requirement for the space.
GFCI Testing Equipment
- A variety of GFCI testers are available, from simple plug-in units with push-to-test features to advanced branch circuit analyzers.
Outdoor Protection Standards
- Outdoor receptacles must have GFCI protection but are not mandated to require AFCI protection; however, AFCI protection for outdoor lighting is permitted.
