Blue and yellow These colors are used for the live wire pulled through conduit. You'll use yellow mainly as switch legs to fans, structural lights and switched outlets. You'll use blue mainly as a traveler for a three-way or four-way switch.

Similarly, what is a blue wire?
Like other terms for colored wire in IT, blue wire doesn't necessarily mean that the wire involved is shielded in blue—it can be shielded in any color. The term blue wire describes the wire's use, much like the term "purple wire" is used for debugging wire, where the wires involved are often not actually purple.
Subsequently, question is, is a blue wire the same as black? Why Yes; you can connect if both wire are to be use for same purpose, that is if the black wire is use for neutral and you intend to use the blue wire for neutral you can connect. Why No; professionally is not right to use different wire color together, under electrical code. check the IEE code for details.

The "common" is the "neutral" or "ground" wire, depending on the type of circuit. In normal US residential wiring, you'll have a black "hot" wire, a white "neutral" or "common" wire, and a green or bare "ground" wire.Does blue wire go to black or white?
The black wire from the fan is the hot for the fan motor, the blue is for an optional light kit. The wires from the ceiling box are probably a "hot" wire (black), a neutral wire (white), a ground wire (copper), and a switched-hot (red)(see description here).What does a blue outlet mean?

Note: The Yellow/Green wire (Earth) needs to be slightly longer than the blue (Neutral) and Brown (Live) wires, in order to reach the top terminal. It is better to have the cables slightly longer than necessary and cut them to the correct length than try to stretch cables to make them reach the terminals.Where does the switched live wire go?
The permanent live wire is wired into the switch and the switched live into the switched live terminal. The neutrals are connected together using a terminal connector. You can also see that another live and neutral wire go to the next light switch.What is the blue wire in electrical wiring?

Black, Red and Blue are used for hot wires and White is used as the neutral wire in a 120/208 V circuit. Brown, Orange and Yellow are used as hot wires and gray is used as the neutral wire in a 277/480 V. For grounding, regardless of the voltage, Green (or a bare wire) is used.Which is live red or black?
Additions to the old cables mean that some installations will have mixed colours within them. A mixed installation is shown below. You can clearly see that red is connected to the new brown (live), black is connected to the new blue (neutral) and the green and yellow earth stays the same.Can I connect red and black wires together?
In 220-volt circuits, red wires are the secondary live wires. Like black wires, they can be used in some types of switch legs. They are also used to connect hardwired smoke detectors to the home's power system. It's possible to link two red wires together or a red wire to a black wire.What Colour cable is positive?

use a small battery (9V is best), and touch each wire to a terminal, then have your buddy look at the speaker. If the blue is on + and the green is on - and the speaker exerts upwards, then it is the correct wiring. If it exerts downwards, then the polarity is the other way.Which wire colors are positive and negative?
The coloring is as follows: Positive - The wire for the positive current is red. Negative - The wire for the negative current is black. Ground - The ground wire (if present) will be white or grey.Can black and blue wires go together?
Connect the black and blue wires in your fan if you only have 1 switch. Connect the black and blue wires coming out of your fan. This will allow you to control your fan and lights with a single switch. Twist the copper ends of the black and blue wires together like you did with the previous wires.What Colour is blue wire?
