Does the red or black wire go on top?
It doesn’t matter which traveler wire (red or black) connects to which traveler terminal as long as it’s the same in both switch boxes. For example, if the red traveler wire is on the top traveler terminal in the first box, it should also be on the top traveler terminal in the second box.
How do you know what color wire to use?
The National Electrical Code (NEC) says that white or gray must be used for neutral conductors and that bare copper or green wires must be used as ground wires. Beyond that are general, industry-accepted rules about wire color that indicate their purpose.
Which color is live wire?
brown
The live wire is brown in new systems and red in old systems. The neutral wire is blue in new systems and black in old systems.
Does white or black wire go on top?
The white (neutral) wire connects to the silver screw, or you place it in the back wire hole on the same side of the device as the silver screw. The black (hot) wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw.

- Neutral – White.
- Ground – Green, Green with Yellow Stripe, or Bare Wire.
How can you tell the color of a wire?
WIRE CODE IDENTIFICATION. Each wire shown in the diagrams contains a code (Fig. 1) which identifies the main circuit, part of the main circuit, gauge of wire, and color. The color is shown as a two-letter code, which can be identified by referring to the Wire Color Code Chart (Fig. 2).

What kind of wiring is red and yellow?
Red wires are commonly found in sheathed, multi-conductor cable. These are called travelers and typically used for two-way switch wiring. Since red wires still conduct current, they are considered hot. Yellow and blue wires are sometimes used in more complicated circuits.
