Cut all the wires simulatenously
it is probably a short circuit if it is dimming your lights. the smoke is burning insulation on the wires. it must be an wire that is not protected by a fuse. do you have an aftermarket stereo?
A straight 220V circuit utilizes two wires per circuit.
They are the wires through which current flows when the circuit is closed.
A circuit breaker does not "cause" smoke. A circuit breaker "breaks" a circuit when there is too much current, creating a hazardous condition for the wires that are connected to the circuit breaker. The circuit breaker PROTECTS you from electrical fire. Find the source of the smoke; what burned? If a circuit breaker tripped during the incident, it is usually caused by melting/burning wire insulation, either inside or outside of an appliance. If the insulation inside the walls of your house has burned/melted, it could be that the circuit breaker was too large for the wire or that the circuit breaker failed to shut off at the appropriate current load. If the circuit breaker failed, your insurance should help you. If an appliance overloaded the circuit, your insurance should help you. If someone connected an oversized circuit breaker, causing the wire to overheat, your insurance company may refuse to help you.
Neutral wires are actually ground wires. They enable the circuit to be completed.
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.
A circuit without any nonconducting wires
well ummm...... the circuit has metal in it to carry on the wires!
The wires carrying the power.
When a switch is open (wires not connected) it is considered off. When a switch is closed it is considered on. If you move a switch and the wires are not connected the the circuit is open and current cannot run throughout the circuit to power the device.
wires that have got good conductivity and less losses
Not likely sounds like a blown head gasket
