What do I connect the GREY wire to?
White and Gray Electrical Wires
The colors white and gray indicate a neutral wire. That means it connects to an electrical panel’s neutral bus bar.
What does GREY cable mean?
Gray Neutral Wire
What is a Gray Neutral Wire? The neutral wire (whether gray or white) is used to connect a conductive piece of metal (known as the neutral bus bar) to the electrical panel so that it can attract the current and distribute it throughout the facility.
What is the gray wire in a ceiling fan?
neutral conductors
White and gray wires are normally used as neutral conductors. The 2011 National Electrical Code required a neutral in every switch box to accommodate new devices like motion sensors, occupancy sensors, home automation switches, and dimmers.
Where does the GREY wire go?
The National Electrical Code states that grey wire must be used for neutral conductors.
What does a grey wire mean in electrical?
neutral charged wires
White or gray wires indicate neutral charged wires. However, neutral wires may carry power and pose a danger of electrocution if not handled properly. White and gray wires carry power back to the service panel. Both hot and neutral wires have the potential to shock and injure you if not handled properly.
Is grey neutral wire?
US, AC:The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripe for the protective ground. In principle any other colors except these may be used for the power conductors.
What Colour is grey wire?

What is grey wire in light switch?
Yellow = Grey. All of these switch wires are live, so red sleeving is used on the black, blue and yellow wires.
Is the grey or white wire positive?
The coloring is as follows: The positive current must be red. The negative current must be black. The ground wire, if present, must be white or grey.
What color wires go together for a ceiling light?
One of the black and white wires goes to the light fixture. The other black and white wires are the electrical circuit for the switch. If the light can be turned on or off from switches at each side of the room, you’ll see a blue wire that connects the electrical circuits for three-way switches.
Which Colour wire is live?
Plug wiring colours
| Wire | Colour |
|---|---|
| Live | Brown |
| Neutral | Blue |
| Earth | Yellow and Green |
What are the brown grey and black electrical wires?
Where a three-core cable with cores coloured brown, black and grey is used as switch wires, all three conductors being line conductors, the black and grey conductors should be marked brown or L at their terminations.
Is grey or black neutral?
Brown is always L or SL, black is always SL, grey is always neutral.
Is a grey wire live?
The internal 3-core and earth electrical cable colours comprise a live brown wire, a neutral grey wire, a green/yellow protective earth wire and an additional black conductor which we have discussed as the live line 2 wire.
What is the grey wire in a 4 core cable?
L3
Black = L2 (Live) Grey = L3 (Live) Blue = Neutral.
What is a 4 wire used for?
Four-wire is used for “two-way” circuits, and for cases where two circuits are running to the same place (independent control of a ceiling fan and its lights, for example).
