Final answer:
Electrical outlets should be replaced with GFCI designated outlets, and service panels with AFCI designated components, to protect against electrical shocks and fires.
Step-by-step explanation:
To answer the student's question: Electrical outlets should be replaced with those designated Ground Fault Circuit Interrupter (GFCI); Service panels and their components, and other connectors designated by the utility should be replaced with components designated Arc Fault Circuit Interrupter (AFCI). The correct answer is option C: GFCI; AFCI.
A three-hole outlet, or the standard three-prong plug, ensures the proper function of the three-wire system, which includes live/hot, neutral, and earth/ground wires. The earth/ground wire is a critical safety feature that prevents electrical shock by forcing the appliance's case to be at zero volts in case insulation is worn out or damaged. A GFCI protects individuals from shock by detecting loss of current, whereas an AFCI guards against fires by detecting electrical arcs in circuits.
