Wiring methods installed behind access panels must be supported according to applicable articles. This requirement ensures that the wiring is secure and protected from physical damage, which is critical for maintaining safety and functionality. Support is necessary to prevent sagging or excessive movement, which could lead to wear and tear over time, potentially creating hazards such as short circuits or electrical failures.

While painting or using metal raceways may provide additional protective features, the primary requirement in this context is the need for proper support of the wiring methods. Ensuring that wires are adequately supported directly addresses issues of safety and compliance with electrical codes, which mandate that all wiring is installed in a manner that minimizes risks associated with electrical installations.
