Also black wires are often used as switch legs in circuits which is the connection linking a switch to the electrical load. What the color of an electrical wire means.

What color is load wire. This color of wire is used to transfer power to switches and outlets in all types of circuits. According to nec a black or red wire must be used as an ungrounded conductor or hot wire. Its also possible to have some other colors may come into play depending on the system. The coloring is as follows. Once you identify the wires use the labels provided in the orro switch packaging to mark them and attach the wires to the correct port on the back of the switch. The color for the line wire is usually black and load wire is usually red black or blue less common.
What color is the load wire. If you notice that both are the same color for you please use the guideline below to determine which wire is which. Positive the wire for the positive current is red. For instance a white wire in a two wire cable may be used for the second hot wire on a 240 volt appliance or outlet circuit. In fact any color wire except white gray or green may be used in conduit to carry ungrounded power. In a circuit the main load wire the live power wire between the switch and power source is typically black and the secondary load wire is usually red.
Distinguishing between line and load isnt always necessary. These are considered the hot wires and carry the current to the devices. Typically this is indicated with a band of black or red electrical tape but other colors may be used wrapped around the wires insulation. For example a conventional wall switch which is a single pole single throw switch works equally well whether you attach the live circuit wire line to the top brass terminal or the bottom because the switch has only two positions open or closedthe terminal connections are directional on a double throw switch on the. A yellow and blue striped wire may also be used for power in a circuit but only in applications that dont require the heavy duty demands of a traditional wall power outlet. Line connections have wires attached to them in colors like black red and blue.
Negative the wire for the negative current is black. All nm cables contain the basic black insulation and white insulation wires plus the bare copper or green insulated ground wire. What is the color of the load wire. Ground the ground wire if present will be white or grey. Wire colors can vary between circuits so it is best to remove or turn off power sources before touching them. No wire with any of those colors can be used for establishing a ground or neutral connection.
Neutral wires should be white. And ground wires are often plain copper but the ground wire color can be green. However if you see a white wire with electrical tape on it that may indicate that its being used as a hot wire. White wires are used for neutral connections while green or bare copper wires are used for ground wires. The wires inside an nm sheathed cable are color coded to make it possible to identify each one at both ends of the cable and wire correctly.
