Can you use two wires with one neutral?

If the two circuits are from the same line, the main danger is overloading the neutral with too much current. A fire hazard as the neutral is not connected to a breaker. In short, stay safe and run separate neutrals for each circuit. you definitely do not want to share neutrals from different circuits.

Can you put a neutral and live wire together?

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.

Can I run a single neutral wire?

You can retrofit a ground like you did, but you cannot retrofit just a neutral. The main reason is that all conductors must run through the same cable or conduit, and currents must be equal in each cable: power must go back the way it came.

Can 2 live wires touch?

No. That won’t work. 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.

What happens if you switch live and neutral?

Can you connect one neutral wire to many live wires?

No. You can’t connect 1 neutral wire to many live wires. You can connect 1 neutral wire to 2 live wires, as long as those 2 live wires come from the 2 different poles of your electrical service.

What is the difference between a switch and a neutral wire?

A Neutral wire is used for a return path to complete the circuit (For an electrical current to flow) A Switch is a device used to remotely turn an electrical system on and off or to isolate a electrical system as in a fuse box switch.

Is it safe to run two neutrals from different circuits?

A fire hazard as the neutral is not connected to a breaker. In short, stay safe and run separate neutrals for each circuit. you definitely do not want to share neutrals from different circuits.

Can a neutral wire act as a current return?

So although a live wire from a secondary source can make a circuit and act as a current return it is not a true Neutral as it is not designed to be so and will most likely cause damage somewhere. Neutral wires can be safer then Live wires that can have a high potential but they may not be the same as ‘Ground’ or ‘Earth’ wires.
