[ad#block]Electrical Repair Question: How should I Identify Electrical Conductor Wiring?

My electrical inspector told me I needed to “Re-identify all white conductors in cables used for ungrounded conductors”.

This home electrical question came from: Tammi, a Homeowner from Cary, North Carolina.

Additional Comments: great idea, hope it solves my issue.

Thanks for your electrical repairs question Tammi.

Re-Identifying Ungrounded Neutral Conductors for Electrical Wiring

Tammi, You have not identified the equipment that the inspection is referring to therefore I am unsure about the circuit that the inspection is referring to, as well concerning re-identifying the white conductors in the cables that are used, however pay close attention to the Cables that are used, and the Neutral wire conductors because this is what the inspector is concerned with. If the equipment and circuit is 240 volt and the circuit has been fed with a 2-wire cable with ground then the white wires that will be used as hots will need to be identified with black electrical tape. If the equipment and circuit is 120 volt then the Neutral wires should be identified with white electrical tape if needed.  Keep in mind that your electrical inspector should be available by calling your local building department and you may ask for clarification about anything having to do with your project. If your inspector does not provide the help that you need then ask to speak to their supervisor or the manager of the building department.
