When a krital system fails and thee wiring is not labeled, thee diagstic process becomes a posture hunt. Electricans mutt trace each cable back to its origin, often using tone generators and probes.

Te Wire Pulling Process: A Critical Window for Labeling

Te moment wires are pulled dupligh conduit or laid into trays is thea ideal time to label them. At this stage, wires are accessible, their identifies are known from thae print, and appliying labels is everforward.
