White and black wires positive negative. In direct This guide explains wire polarity, the meaning behind wire colors (like black, red, and white), and simple ways to identify each wire—with or without If the meter’s red (positive) probe is touching the positive wire and the black (negative) probe is touching the negative wire, the display will show a positive voltage value. In these instances, red is also hot, which makes the color positive. In direct current, the red is positive, black is the negative wire, and white and gray wires are for grounding.
