The Brown (Live) wire (br = bottom right) goes into the hole on the right, connected to the fuse (which should be clipped in).

The green and yellow wire is the earth wire, and goes through the middle up to the hole in the top..

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.

Why are there 2 hot wires?

The reason for multiple hot/neutral wires for one outlet is that the outlets are daisy-chained together. This means hot/neutral is only coming from one of the wires and it is being sent to the other wire.

What Colour wires go in a plug?

Why does my outlet have 3 wires?

Three-conductor wire has two hots — black and red — and a white neutral. Though normally used for three-way switching, three-conductor wire is commonly used for duplex receptacle wiring as well. … The black or the red can go to a permanently hot feed, while the other goes to a wall switch, creating a switched outlet.

Can I put 2 Live wires together?

If you put two “live” wires on a switch, they don’t play any “role” at all. They are what they are. If they are both “live” wires there are two possibilities. … If you close the switch, you will create a direct 240volt short circuit.

What happens if you wire live and neutral wrong?

If you’ve swapped the live and neutral wires then even with the switch off all of the wires and load inside the appliance are energized so it’s much easier to get shocked. … If it’s wired correctly then the screw shell will be on the neutral side, so safe if you accidentally touch it.

How do I change a 2 wire plug to a 3 wire?

InstructionsFirst and foremost, turn off electricity to the circuit you’re working on. … Unscrew the top plate. … Remove the outlet from the electrical box. … Move the wires from the old outlet to the new. … Ground them outlets. … What to do with an open ground. … Put everything back. … Test your work.

What happens if you connect the wrong wires on a light fixture?

The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.

Are wires live when switch is off?

If someone wired it incorrectly, they may have switched the neutral so that the light socket is always live. … If your light switch is a dimmer, then the socket is still live. You can still get enough current to kill you, or even just knock you off of the ladder and cause secondary injuries. Turn off the breaker.

What are the 3 types of wires?

Expert Answer:The electric power line enters our house through three wires- namely the live wire, the neutral wire and the earth wire.To avoid confusion we follow a colour code for insulating these wires.The red wire is the live wire, and the black wire is neutral.The earth wire is given green plastic insulation.More items…•

When wiring a plug what Colour is the neutral wire?

The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.

Can you wire a 3 pin plug with 2 wires?

Yes it is safe to connect the 2 wires to line (Brown) and neutral (Blue) and leave the Earth (Green/yellow) disconnected. The earth pin opens a shutter to allow the other pins to be inserted into the socket.

Can you run two wires one breaker?

If your circuit breaker is not designed to hold two wires, you have an issue on your hands that could be dangerous and that you should not ignore. With two wires connected to the same breaker or terminal, the circuit breaker could overheat. If the two wires are not fastened tightly enough, this could result in arcing.

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.

What happens if 2 Live wires touch?

Whenever two wires are at different voltages, current will pass between them if they are connected. Your body can connect the wires if you touch both of them at the same time. Current will pass through your body.
