If three phases and a neutral are mounted on a crossarm, the neutral can be identified as it is the one mounted on a ? insulator.

Explanation:
On a crossarm with three phase conductors and a neutral, the neutral is identified by its insulator material. Glass insulators are traditionally used for neutrals, making that conductor visually stand out from the live phase conductors, which typically use ceramic or polymer insulators. This difference helps line crews recognize the neutral quickly and safely.
