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.

What is a neutral wire used for?

Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.

Is a neutral wire positive or negative?

When live (phase) wire is positive, neutral wire is negative. When phase wire turns negative, neutral wire becomes positive. And it goes on. In practice, neutral is grounded for safety reasons.

What happens when neutral touches live?

The path from the live to the neutral wire has very low resistance and will create a short circuit if the large current exceeds the fuse rating. There will be a blow. The earth wire is touched by the live wire.

What happens when connect live to neutral?

It is the condition of the short circuit if the live wire directly comes to the neutral wire. … If Normal wire burns, the circuit will break and everything will become normal except for that wire.

What is the purpose of live wire?

Each wire in the mains cable has an important function: The wire covered in brown plastic is the live wire. This carries the 230 V alternating potential difference from the power supply. The wire covered in blue plastic is the neutral wire and this completes the circuit from the appliance back to the supply.

Is the neutral wire white or black?

Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.

What happens if neutral and ground touch?

The neutral is always referenced to ground at one, and ONLY one, point. If you touch the neutral to ground anywhere else, you will create the aforementioned ground loop because the grounding system and the nuetral conductor are now wired in parallel, so they now carry equal magnitudes of current.
