What is the blue wire on a ceiling fan?

The blue wire on a ceiling fan typically refers to the wire that is responsible for connecting the fan's light kit. This wire is used to power the lights on the fan. However, it is important to note that the wiring configuration may vary depending on the specific brand and model of the ceiling fan.

In most cases, the blue wire is meant to be connected to the light kit's wiring or the main wiring inside the fan's housing. This allows for proper electrical connectivity and enables the fan's lights to be controlled separately from the fan itself.

It is always recommended to consult the manufacturer's instructions or a professional electrician for specific guidance on wiring a ceiling fan, as incorrect installation can lead to electrical hazards or damage to the fan. Furthermore, local electrical codes and regulations should be followed when performing any electrical work.
