What is the maximum spacing between supports for aircraft electrical wiring?

Explanation:
Wiring needs to be secured so it cannot move, rub, or vibrate against structure or sharp edges. The maximum spacing between supports is 24 inches, which means you must place a support or clamp no more than two feet apart along the run of wire. This distance helps prevent insulation wear and wear on conductors due to vibration, while keeping routing practical and not overly cumbersome. In areas with high vibration or where wiring is routed through tight passages or near equipment, you would use closer supports or added protection. The other options are too restrictive (tighter spacing than required) or too loose (allowing more movement than allowed).
