Often asked: How To Wire A Wall Plug?

How do you wire a plug socket in South Africa?

Unscrew the little screws on each of the plug’s pins. Insert the twisted copper wires into the holes in the pins. The green and yellow wire must always be inserted into the top pin. The blue wire is inserted into the left pin (the pin is marked with a blue spot or the letter N).

Where do wires go in a plug?

In a plug, the blue neutral wire goes to the left, the brown live wire to the right and the green and yellow striped earth wire to the top.

Which side does the white wire go on an outlet?

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.

What happens if you wire a plug wrong?

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.

How do you wire a 3 wire plug with 2 wires?

  1. Here’s how to replace a 2pin plug with a standard 3pin plug:
  2. Cut off the 2pin plug at the end of the cable.
  3. Use the same sharp knife to split down the middle of the cable, so that you cut between the two wires inside the outer protective layer.
  4. CONTINUES BELOW.

What Colour wires go in a plug?

(L) = Live = Brown. (N) = Neutral = Blue. (E) = Earth = Yellow & Green.

Which side of the plug is the black wire?

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.

How do you wire a 3 wire plug?

Open the replacement plug so you can reach the terminal screws inside. Attach each section of exposed copper to the appropriate terminal screw: green wire to the green grounding screw, white (neutral) to the silver screw, and black (“hot”) to the brass screw.

Does it matter which wire goes where on an outlet?

Attach the Neutral and Hot Wires to the Receptacle

For standard outlet wiring, the white neutral wire can go on either of the two silver terminals, since they are interchangeable. Likewise, the black hot wire can go on either brass screw terminal.

Why does my outlet have 2 black and 2 white wires?

The two black conductors are electrically bonded through the receptacle, as are the two white conductors. You’ll notice that the bonding tab on the side of the receptacle is still in place, which means that the two receptacles are connected together.

What happens if you connect white wire to black wire?

In that case if you just touch the bare wires together you get a short circuit. It will produce a big spark and hopefully blow a fuse or trip a breaker. If you wire them together and then turn the power on, the spark will occur at the breaker or fuse. Either way, don’t do it.

What happens if you mix up 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.

What happens if an outlet is wired backwards?

If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off.

Can Reverse polarity cause a fire?

Watch out: Reversed polarity on an electrical outlet is dangerous. If you accidentally reverse these wires the device you plug in to the receptacle may “work” but it is unsafe and risks a short circuit, shock, or fire.
