What is GREY electrical wire for?
The National Electrical Code states that grey wire must be used for neutral conductors. These wires may still carry power that can give an electric shock and injure you. Neutral wires deliver power back to the service panel. The standard grey wire is known as the Line-phase 3 in its AC code.

Here’s a rundown of electrical wires: The black wire is the “hot” wire, which carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, which takes any unused electricity and current and sends them back to the breaker panel.
What happens if you reverse hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.
What wire does the blue wire connect to?
Blue wire is for the light, if light is included with the fan. White wire is neutral. Green wire is for the ground. Red wire is sometimes included and acts as a conductor to carry power to the light kit.

In a plug, the live wire (brown) and the neutral wire (blue) are the two wires that form the complete circuit with a household appliance. The earth wire (green and yellow) does not normally form part of the circuit and is included as a safety wire.
What are the blue and brown wires?
The blue wire is known as the neutral wire and its job is to take electricity away from an appliance. The brown cable – known as the live wire – actually delivers electricity to your appliance. Together, these two wires form a complete electric circuit.
Is the grey wire neutral?
