14 2 black wire to 14 2 white

My house is older and has the old 14/2 (black) wire running through the house and I want to rig a 3 way switch. The only wire I can find is the 14/2 (white) wire.

The wires are the same guage and have two colours and a bare when you strip the casing off.

I am just wondering if the 14/2 black is the same as the 14/2 white or are they made to carry more amperage or something like that?

The wire itself is the same and carries the same number of amperes, but there are rules when you can use white versus black.

When using premade cables, sometimes the white wire is needed when connecting up a switch. A neutral is never connected to a switch terminal so a white wire on a switch terminal is not neutral. In that case the switched power (to the light, etc) goes on the black wire.

To connect 3 way switches, 3 conductor cable (14-3 on 15 amp circuits) is needed and preferably run directly from one switch to the other switch. Here use red and white for the travelers.

Put a band of red or black tape or stain on each end of a white wire connected to a switch.

For wires strung individually (through conduit) white is for neutral only.


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

the wire are the same, they don't use black for 14-2 they use white for 14-2, yellow for 12-2, orange for 10-2, and black for lower gauge wire ,you will need 14-3 for three way
