When it comes to wiring a home or an appliance, one of the most common questions arises: is red electrical wire live or neutral? For those who are uncomfortable with electricity, this can be an intimidating query, as it’s important to get the answer right. Fortunately, this question is quite straightforward to answer.
The color-coding of wires is an area that is regulated by electrical codes, and the most commonly accepted standard is outlined by the National Electrical Code in the United States. As far as red wire goes, it is almost always used as a “hot” wire. This means that it carries the electrical current from the device’s power source to the device itself. It will be connected to a breaker in your home’s circuit box, so it will be live even when the device is turned off.
In contrast, neutral wires are usually color-coded white. Neutral wires carry the electrical current directly from the source to the ground. They do not typically carry power when a device is turned off, but they can become dangerous if a ground fault occurs. If you come across a wire that is color-coded differently than above, make sure you turn off power at the fuse box before making any alterations.
In summary, out of all colored wires, red electrical wire is almost always designated as a live wire, meaning it carries the electric current from the device’s power source to the apparatus. On the other hand, neutral wire is color-coded white and carries the electrical current back to the ground. In both cases, it is highly recommended to disconnect power from the main fuse box before any changes are made to ensure safety.
