Can live and neutral be connected together?
You cannot mix these three wires.
You will have to use the two channels separately with each using the common wire.
Yes, you can.
Everyone talks about the live (hot) wire being dangerous, but can the neutral wire also be dangerous because current flows through it too?.
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.
Will reverse polarity trip a breaker?
Reverse polarity will not trip a breaker. Only a dead short will. Pull the receptacle out and give us clear pictures of all the wires and connections. It sounds as if you have connected the grounded neutral conductor on that circuit to the hot wire, probably at the receptacle terminals.
What happens if wires are backwards?
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.
What happens if you mix up live and neutral wires?
If you swap live and neutral which are connected to a lamp, yes it will work fine. However, the switch on the lamp is connected on the Live side. So even though you have switched the lamp off, you have only broken the neutral return path and the light itself is still live.
What happens if you connect 2 hot wires?
You either have no voltage difference between the two wires, or you will get hot wires from opposite hot legs and you will end up with a 240 volt dead short. In that case you will trip at least one circuit breaker, or possibly 2. … If you bring two hots to the switch from the same phase, nothing will happen.
Which wire is hot when both are black?
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.
Why would a neutral wire be hot?
If the neutral is disconnected anywhere between the light bulb and the panel, then the neutral from the light to the point of the break in the neutral will become hot (and the device will be unpowered, because no current will be flowing through it).
What happens if phase and neutral are shorted?
In mains circuits, short circuits may occur between two phases, between a phase and neutral or between a phase and earth (ground). Such short circuits are likely to result in a very high current and therefore quickly trigger an overcurrent protection device. … A short circuit may lead to formation of an electric arc.
What happens if live and neutral are reversed?
If the switch is put in the neutral line (like in your house) the switch and fuse comes in neutral line. In the switch OFF position the entire appliance will have 220V, touching any part will give you deadly shock. As per the rules, if live and neutral are reversed, Electricity board will not give power to your house.
What happens if you connect hot to neutral?
Because the hot wire completes a circuit by coming in contact with the earth, if you touch a hot wire and you’re in contact with the earth (which is pretty much always), you’ll become part of the circuit. In other words, you’ll get shocked. … The socket is always connected to the neutral wire, so no big deal…
