The 2-inch separation rule does not apply to which type of cable?

Explanation:
The test is about why some cables don’t require the 2-inch separation from other conductors. That rule exists to keep low-voltage signaling away from high-voltage power wiring to prevent interference and false readings. Twin-axial cable is built with two conductors inside a single jacket and, importantly, a shield around them. That shield provides strong isolation from nearby electrical noise, so you don’t need to keep that 2-inch gap. Other cable types don’t have the same shielding arrangement, so the standard separation guideline generally still applies to them.
