Thank you for requesting me to answer your question.

Are you just asking what to do with the unneeded white wire?
Expert:  Jason replied 2 years ago.
If so, you can simply cap the white wire in the outlet box. You can either cap it in the breaker panel, or go ahead and connect it to the panel's neutral bar.
