Understanding these colour codes before attempting any DIY (DIY) electrical system repair is essential. Remember that every electrical wire could carry an electric current at some moment, so you should treat each coloured wire with the same caution. If you are unsure about electrical work, you should leave the work to a trained professional.

Colour of an Electrical Wire

Black Electrical Wires

The colour of the wire is used to transmit electricity to outlets and switches across all circuits. Additionally, the black cables are frequently utilized to serve as switch legs in courses, and this is the link that connects switches to the electrical load. All black wires should always be active.

Red Electrical Wires

In circuits with 220-volt voltage, red wires are second live wires. Like black wires, they are also used in certain types of switches. Additionally, red wires are utilized to connect smoke detectors wired to your home's power system. It is possible to connect two red wires or connect a red wire with an uncoloured wire.

Blue and Yellow Electrical Wires

Although these colours' wires provide power, they're not used in standard outlet wiring. Instead, yellow and blue wires are utilized as live wires, pulled through conduits. For example, you could consider yellow wires as switch legs for ceiling fans, structural lights, and outlets paired with lighting switches.

In addition, blue wires are typically employed as travellers for four- or three-way buttons (for example, if there are switches on the top and bottom of the staircase controlled by one light source, it's the case with a 3-way switch).

White and Gray Electrical Wires

Suppose you see wires in any of these colours; you've found neutral wires. White is the most frequently used; however, grey cables perform the same purpose. The primary function of the neutral wire is connecting the neutral bus bar, an electrically conductive metal piece in an electrical panel which can draw electric current for distribution throughout the home.

 The grey and white electrical wires are only connected. Although they're referred to as "neutral" wires, they could still carry current, mainly when the load in the circuit is not balanced; thus, handle these wires carefully.

Green Electrical Wires

The reason for these green or blue wires is that they ground electrical circuits. They are connected to the grounding terminals in an outlet box and then click through the ground bus bar on an electric panel. In this way, the green wires are an emergency escape route, providing electricity with a pathway to escape to the ground if any live wire in the circuit is in contact with metal or any other conductive. Green wires are only connected directly to green cables. If there's an issue in your circuit, the green wires might be alive; therefore, you should treat them cautiously.

Wires that are flame retardant from Nakoda comprise top-quality superior temperature-tolerant insulation, with properties to fight fires that stop the spreading of flames in unexpected accidents. They have higher than average oxygen and temperature indexes which allows for much greater tolerance to heat, which helps that your power supply is uninterrupted for longer.
