Yes, as long as it is in very good condition and is modern wire.
NEC 310.16 conductor ampacities NEC 240.4(D) For residential installations the smallest wire to be used is 14 AWG (15 amps rating) and for commercial installations the smallest wire to be used is 12 AWG (20 amp rating)
The recommended ground wire size according to the NEC Ground Wire Size Chart is based on the amperage of the circuit.
The recommended ground wire size for a NEC-compliant electrical installation is typically determined by the size of the circuit and the type of wiring being used. It is important to consult the National Electrical Code (NEC) or a qualified electrician to determine the appropriate size for your specific installation.

The National Electrical Code (NEC) does not specify a minimum wire size for running wires in parallel. However, it is recommended to use wire sizes that are appropriate for the current load and to follow industry standards and best practices. Typically, wire sizes are chosen based on the current-carrying capacity needed for the circuit.

The National Electrical Code (NEC) permits a minimum wire size of 14 AWG for general lighting and receptacle circuits in parallel installations.
The NEC wire gauge chart provides information on the recommended wire sizes for different electrical applications based on factors such as current capacity, voltage rating, and insulation type.
The NEC wire size chart provides information on the appropriate wire size to use for different electrical applications based on factors like current capacity, voltage, and insulation type.
The NEC wire fill chart provides information on the maximum number and size of wires that can be safely installed in a conduit or raceway for electrical installations.
The wire fill chart in the NEC provides information on the maximum number and size of wires that can be safely installed in a conduit or raceway, helping determine the appropriate wire size for electrical installations.
