3 Prong Outlet Wiring Diagram

Wiring a 3 Prong Plug The power cord has a white wire, green wire, and a black wire. The white wire is connected to the silver or light colored screw, the green wire is connected to the green screw and the black wire is connected to the gold or dark colored screw.

What color wire goes where on a 3 prong plug?

Modern 120-volt residential electrical circuits have three color-coded wires. The three wires are a hot wire, which should be black or sometimes red; a neutral wire, which should be white; and a ground wire, which should be green or bare.

How do you wire a 3 pin plug correctly?

Attach the flex to the plug

1. Green/yellow wire to earth terminal (E)
2. Blue wire to the neutral terminal (N)
3. Brown wire to live terminal (L)

Which is positive and negative on 3 prong plug?

The red wire is positive. The black wire is negative. The white wire (if present) is ground (sometimes called neutral in DC). If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive.

Which color wire goes to the wide prong?

White (neutral) wire, silver screw (wide blade).

Which wire goes to which prong?

A polarized plug will have one prong wider than the other, which is the neutral, and usually silver-colored prong. The hot prong will be narrower and usually gold colored. With a non-polarized plug, you can wire either wire to either prong.

Does it matter which side of outlet is black wire?

White (neutral) goes on the side allocated for the larger prong. Black (Hot) goes on the smaller prong side or white to silver screws, black to gold screws. Ground (bare wire) to green.

What color is the hot wire on an outlet?

Hot wire is identified by its black casing. This is the main color of hot wire for most homes. However, other hot wires can red, blue, or yellow, although these colors can indicate a different function besides powering an outlet.

Which side of plug is positive?

Which side of a 2-prong plug is positive? Because we use A/C current, prongs don't have have a positive and negative. Instead, the two prongs have a 'hot' and 'neutral' side. The wider prong connects to the neutral wire and the smaller prong smaller prong is the hot side of the circuit.

Can I use a plug without earth pin?

If the appliance, which has a plug connected to its power lead is double-insulated, then no earth wire is necessary, however if the appliance has a metal body, then it is best to ensure that the metal body of the appliance is earthed, just in case of a fault condition, as an earth connection to the metal case will

What are three wires in three pin plug?

1. A Earth wire.
2. B Live wire.
3. C Neutral wire. A 3 pin plug consists of an earth wire, a live wire and a neutral wire. The earth wire is a very important component that helps protect the user from electrical shocks.

How do you wire a plug step by step?

How to wire a plug step by step guide

1. The blue wire connects to the neutral terminal, to the bottom left.
2. The brown wire connects to the live terminal, to the bottom right attached to the fuse.
3. The yellow and green is the earth wire, which connects to the earth terminal at the top.

Is the large prong hot or neutral?

Why One Prong Is Bigger. Polarized nongrounding-type plugs have one prong, the neutral, that's larger than the other to ensure that the hot wire, which is the smaller one, is tapped correctly.

Is the wide prong hot or neutral?

The wide prong on the plug links the threaded base of light bulbs to the neutral terminal (the wider slot) in the receptacle. The hot side of the outlet (the side that can deliver a shock) is wired to the threaded socket if the wires are reversed.

Does it matter how you wire a plug?

So although flipping the plug around and inserting it backwards will probably be no problem with regard to the electrical operation of the appliance, it may create a safety hazard by exposing the "hot" half of the outlet, the half not connected to Earth, such that someone might touch it and be shocked.

Which slot is hot on an outlet?

An outlet has three holes. The first hole, or left hole, is called “neutral”. The second hole, or right hole, is called “hot”. The third hole is the ground hole.

Which is the hot wire ribbed or smooth?

The ribbed side of the line cord indicates the neutral wire, the smooth side, the hot wire. If we are wiring a line cord plug, the ribbed wire would connect to the wider space or neutral space on the plug itself.

What happens if I wire an outlet backwards?

But here's the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

What happens if an outlet is wired wrong?

One common issue with electrical outlets is reverse polarity, also known as "hot-neutral reversed." In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your electrical items, it is also present a greater shock hazard.

Does the hot wire go on the top or bottom of a outlet?

It's up to you, there is no standard electric outlet orientation. So that means there really is no such thing as upside down outlets. One way isn't safer than the other — as long as the outlet is wired correctly. It all comes down to aesthetics, so install them whatever way looks best to you.
