How should Type FCC cables be covered when installed on floors?

Type FCC cables are specifically designed with a focus on fire resistance and minimizing potential hazards. When it comes to covering these cables, using carpet squares is an effective choice. Carpet squares provide a non-slip surface, which is important for safety, as it helps to prevent tripping hazards in areas where people walk.

Additionally, covering the cables ensures they are protected from physical damage and minimizes the risk of accidental unplugging or tampering. Carpet squares also allow for easier access when maintenance is needed, as they can be easily removed or replaced. This method balances safety, accessibility, and protection for the cables in a flooring environment, making it the most appropriate choice among the given options.
