Can extension cords be used in place of permanent wiring?

The use of extension cords is not permitted as a substitute for permanent wiring because they are not designed for continuous use in the same way that fixed wiring is. Extension cords are intended for temporary power needs and can pose significant safety hazards if used as a permanent solution. Over time, extension cords can become damaged, leading to risks such as electrical shorts or fires. Also, they are often not rated for the same environmental conditions as permanent installations, which can further increase the danger when used improperly.

Permanent wiring follows specific codes and standards set by electrical authorities to ensure safety and reliability, while extension cords do not meet the same criteria for long-term installation. This understanding helps ensure that electrical systems are safe and effective in supporting the needs of buildings and their occupants.
