Wire Marking Questions and Answers

Marking wires, whether it be in a data management center or within a manufacturing facility, is incredibly important for the safety of electricians and others who work closely with the facility’s wiring infrastructure. Wires may become worn and need replacement, but that cannot be done safely if the employee is unable to identify the wire, the location of the issue, or the problem entirely. For that reason, there are several wire marking standards that exist and have been proven to be effective when implemented properly.
