Where must electrical receptacles be installed in dwelling units?

In dwelling units, electrical receptacles must be strategically installed to ensure accessibility and convenience for everyday use. The requirement to place receptacles at least every 12 feet along walls and within 6 feet of doorways is crucial for promoting safety and functionality in residential spaces. This guideline helps prevent the use of long extension cords, which can create tripping hazards and overloading risks.

By placing receptacles within 6 feet of doorways, it ensures that individuals can easily plug in devices as they enter or exit a room, enhancing usability in high-traffic areas. Additionally, spacing them no more than 12 feet apart helps minimize the distance between outlets, catering to the wide range of electronic devices and appliances commonly found in modern homes. This design principle ultimately aligns with the National Electrical Code (NEC) standards for residential wiring, which prioritize both safety and practicality.
