What is required in double-gang boxes to isolate TV conductors from power wiring?

In double-gang boxes, isolation of TV conductors from power wiring is essential to prevent electrical interference and ensure safety. A barrier is required between these two types of conductors within the box. This barrier serves to physically separate the wiring, which helps to minimize noise and potential electromagnetic interference that could affect the television signals. Additionally, it enhances safety by reducing the risk of accidental contact between the power wires and the low-voltage TV conductors.

When properly installed, the barrier ensures compliance with the National Electrical Code (NEC) and industry best practices, providing a safer environment for both the electrical system and the user. Other options such as insulating tape, while they might have some applications, do not provide the structural separation required in this scenario. Using a ground fault circuit interrupter (GFCI) is not specifically aimed at isolating the conductors but rather at preventing electrical shocks, and having no additional requirements would not meet the necessary safety and functional standards for wiring installations involving mixed voltage systems.
