Final answer:
Electrical outlets and components should be replaced with those meeting current safety standards, such as the three-wire system and devices like circuit breakers and GFCIs to prevent hazards.
Step-by-step explanation:
Electrical outlets should be replaced with those designated by current safety standards. Service panels and their components, and other connectors designated by the utility should be replaced with components that adhere to regulatory and safety standards specified by the utility or local building codes. Most electrical appliances, fuses, and circuit breakers are rated in amperes (or amps) required for proper operation. To prevent the risk of thermal and shock hazards, a three-wire system is used, which includes live/hot, neutral, and earth/ground wires. The live/hot and neutral wires may vary in color in different regions, which makes it crucial to know the color code for your area. However, earth/ground wires are commonly green, yellow, or bare. Circuit breakers and ground fault circuit interrupters (GFCIs) are also important safety devices designed to protect against excessive currents and changes in current, respectively.
