What type of environment would require a flexible raceway?

A flexible raceway is particularly suited for environments with potential movement or vibration due to its ability to accommodate shifts without causing damage to the wiring contained within it. Flexible raceways can bend and adjust to movement, making them ideal for applications where equipment may be subject to vibration, such as in industrial settings or on machinery. This flexibility helps to prevent stress on the cables and minimizes the risk of breaks or failures.

In contrast, stable and fixed locations typically don't necessitate flexible raceways, as such areas don't experience any movement that would require the added flexibility. Environments without electrical installations, as well as those with excessive moisture, may call for different types of conduits or raceways more suited to their specific conditions, but they do not inherently require flexibility for movement purposes.
