According to WAC, how should extension cords be used?

The correct answer emphasizes that extension cords are designed specifically for temporary use. Their primary function is to provide a convenient way to supply electricity to devices in situations where permanent wiring is not feasible or necessary. Extension cords should be seen as a short-term solution, primarily utilized for connecting equipment in various settings like homes, offices, workshops, and during events.

Using extension cords as a permanent wiring solution can pose significant safety risks, including overheating, potential electrical fires, and damage to the equipment or the electrical system. This is why regulations and codes distinguish between temporary and permanent electrical solutions, insisting that all permanent installations must use properly rated and permanently installed wiring to ensure safety and compliance with electrical standards.

The guidelines do allow for temporary settings—such as construction sites or special events—where extension cords are commonly used for equipment that may not need a dedicated circuit. Choices that imply permanent or primary usage are not aligned with these safety standards and guidelines, which prioritize the appropriate use and operation of electrical equipment in different contexts.
