What should be done if a solid wire is nicked during the stripping process?

Selecting to cut and strip the wire again is the best approach when a solid wire is nicked during the stripping process. A nick can compromise the integrity of the wire, potentially leading to electrical issues such as decreased conductivity, increased resistance, or even complete failure of the wire. Re-striping the wire ensures that the conductor is intact and that the electrical connection will be safe and reliable.

Choosing to leave it unconnected could lead to unsafe conditions, as any exposed or damaged areas might cause short circuits or other hazards. Covering the nick with tape is also insufficient, as it does not resolve the underlying issue with the wire itself. While using a connector might seem like a workaround, it does not address the compromised state of the wire, which could still pose problems during operation. Therefore, cutting and stripping again is the appropriate and safest course of action.
