How should flexible cords be utilized in residential applications?

Flexible cords are primarily designed for use with portable appliances, allowing for easy mobility and connection to a power source as needed. In residential applications, this means they should be utilized for equipment and devices that need the flexibility of movement, such as vacuum cleaners, lamps, and tools that require frequent relocation.

Using flexible cords as permanent wiring for fixtures or as the main power supply for homes is against electrical codes and standards as these scenarios can pose safety hazards. For example, permanent installations require rigid wiring methods that provide secure, protected connections that flexible cords cannot ensure.

While flexible cords can be used in temporary installations in outdoor settings, safety considerations and guidelines dictate they should not be relied upon extensively or as a long-term solution in such environments. Thus, the correct answer aligns with the intended use of flexible cords, contributing to safe and effective electrical practices in the home.
