What type of installation is not suitable for flexible cords?

Temporary decorations
Permanent wiring in structures
Powering small tools
Settings for public events

The correct answer is: Permanent wiring in structures

The idea behind flexible cords is to provide improved mobility and versatility for temporary or portable applications. They are designed for use in situations where electrical devices need to be moved or connected easily, but they are not intended for permanent installations. Thus, permanent wiring in structures is unsuitable for flexible cords because these installations require a stable and secure electrical infrastructure that can handle constant exposure to environmental conditions and mechanical stress. In contrast, flexible cords are typically used for temporary decorations, powering small tools, and settings for public events where the need for mobility and adaptability is greater than the need for a permanent setup.
