Why neutral is current?
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.
Why is the switch 2 neutral hot?
Powered switches need a neutral because they consume electricity themselves, so Switch 2 takes power from the white-with-tape and sends it through the common neutral.
What does "no current" mean on a shared neutral?
No current means no voltage across the switch's power supply which means full voltage on the disconnected neutral wire.
What is the problem with the light on switch 2?
The problem is that the light on switch 2 was routed using the hot and neutral from circuit/leg 2, while the switch itself is powered by the hot from circuit 2 but the neutral from circuit 1, creating circulating currents that can heat metal parts and cause EMI as well as a Code violation (300.3 (B)/310.10 (H)). Moving the light from circuit 2 to circuit 1 fixes it:
Can you remove a hot wire without severing the neutral?
This is why: so you can remove any device for servicing without severing the neutral that other hot wires are depending on.

Do neutrals have breakers?
There's a stupid-simple reason for this: neutrals don't have breakers. The only thing protecting a neutral from being overloaded is the fact that it only returns power for its one hot (or carefully chosen and balanced several hots, in a Multi-Wire Branch Circuit, where it only returns differential current.
What is Faulty Electrical Wiring?
Faulty wiring means there is either damage to the wires, or incorrect voltage running through them.

Improper bonding of neutral bus and ground bus in a sub panel led to electric shock: The owner, intending to make his electrical panel "safer", had violated electrical code and good practice by bonding together the neutral bus and the grounding bus in his electrical panel. There was no ground wire connection back to the main electrical panel, ...
Where is the neutral to ground bond made?
Normally the neutral-to-ground bond is made in the main electrical panel and not in sub panels, lest grounding conductors end up carrying current during normal operations - a shock hazard.
What happens when a fuse opens?
When the fuse opens, the current falls causing the magnetic field to collapse which produces a high voltage. Surge current is probably hot to neutral. If a high voltage distribution wire falls on the wires to a house, the path needs to be back to the high voltage transformer.
Why does the garage electrical system flow through the ground wire?
Because the garage electrical system was carrying current that should have been flowing only on the insulated neutral wires in the building, when the owner touched his grounded metal work bench and was also touching a damp floor, current flowed through the ground wire, through the metal work bench, through the owner, to earth.
Is a service panel suppressor hot to neutral?
There the path is probably hot to neutral. (A service panel suppressor would have current hot-to-neutral.) If there is a utility short that causes a fuse to open, there is high current through the inductance of the power wires that stores energy in a magnetic field.
Is there a ground wire connection to the main electrical panel?
There was no ground wire connection back to the main electrical panel, just incoming hot wires and incoming neutral wire. The panel's incoming neutral wire from the home was not connected. It looked connected but when we wiggled it (power had been shut off at the main building) the neutral wire lifted right out of the connector.

What to do if your light is flickering?
If the light flickers, there is probably a loose connection in the outlet or switch. If you get no response, tap the wall between the working outlet and the dead one. If wires in the wall are loose, you may momentarily make a connection, and the light will flicker. If it does, stop there and mark the wall for excavation and repairs.
Why are my portable heaters brown?
The wattage of the portable space heaters isn't really enough to give you the brown power that you are experiencing (provided that the incoming lines are the proper gauge for the load/run). Low voltage will also not cause the flickering lights that you see - they should just dim (as if controlled by a dimmer). Even the satellite receivers shouldn't be that affected by low voltage (the main circuits are behind a transformer - rectifier setup) and even with the low voltage, would probably remain in regulation.#N#I don't believe that your problem has been discovered yet.
Can satellite receivers be affected by low voltage?
Even the satellite receivers shouldn 't be that affected by low voltage (the main circuits are behind a transformer - rectifier setup) and even with the low voltage, would probably remain in regulation. I don't believe that your problem has been discovered yet.
