Where should wiring be routed in relation to lines that carry fluids?

Wiring should be routed above the lines that carry fluids to minimize the risk of fluid contamination and damage to the wiring. Fluid lines, such as fuel or hydraulic lines, can leak or spill, and routing wiring below these lines would expose them to potential fluid exposure, which could cause insulation degradation, short circuits, or other electrical failures. By positioning the wiring above the fluid lines, technicians can help ensure that any leaks from the lines will not adversely affect the electrical systems, thereby enhancing the safety and reliability of the aircraft systems. This practice adheres to established safety protocols in aviation to protect critical wiring from environmental hazards.
