Common mistakes.
- A. A feeder circuit carries power between a service entrance or main distribution panel and a sub-panel, serving multiple branch circuits rather than a single outlet.
- B. A ground fault receptacle (GFCI) is a safety protection device that monitors current imbalance and interrupts power on a fault - it is not a circuit topology definition.
- D. A daisy-chained series of receptacles connects multiple outlets on a single shared circuit, which is the opposite configuration of a dedicated single-outlet circuit.
