tagging for response from a real electrician.
I've been reading the NEC a lot because I'm going to wire my own house next year. I think that is a no. My reading is that is no longer allowed and the white wire can only be tagged black on the device/light side of the switch, not from the switch to the breaker. I could be wrong though. |

I've seen it done before though uncommon. It's technically referred to as re-purposed or re-tasked. I though about using 10-3 with a red, white and black wires and just not use the white but that opens up a can of worms with it's usual 240V application.

If you're worried about insurance issues, just pay an electrician to do the work.

Use a sharpie marker to re-identify, tape is not permanent. This is an exception for a cable assembly.

DW asked me if I could put in a switch after the house across the street that is uninhabited and for sale just flooded from a water heater failure and the well pump ran for a week or so and flooded the entire house. She wants an easy way to shut off the well when we go out of town. Thanks again PNFLDS. |

Sharpie is acceptable. For the purpose of making a neutral/white into a hot/black tape doesn’t cut it. Tape is for phase identification.

If i read this correctly you are just using a switch with a single 10/2 from the panel? I believe that is technically a code violation
What you are describing doesn't make sense to me 10/2 romex to a switch box, black wire on the switch. From well pump the black wire goes on the other switch screw and you wire nut the whites together in the switch box Unless you are making it 240 volt you shouldn't be tagging any white wire in the panel. If you got a pic i could help more |

If you got a pic i could help more I think he is saying leave wire to pump untouched (except pull it from the breaker). Run new romex from panel to switch. Power for pump runs on the black conductor from breaker to switch then back to panel on white conductor. White conductor is then bonded to black conductor going to pump. |

This makes way more sense. OP is making a switch loop out of his panel. New 10-2 Romex will have black from breaker to switch, and white from switch to existing well pump's black in the panel that was removed from the breaker. Existing well pump's white will remain on the neutral bus in the panel. Just creating a switch loop that begins and ends in the panel. |
