By "clear insulation," I assume you mean the type of wire used in some lamp cords. If so, the hot wire is the one with the smooth (non-ribbed) insulation.
Hot copper wire gives off no fumes.However if you are talking about insulated copper wire, the insulation will give off fumes. Depending on the type of insulation it can be anywhere from totally safe to deadly!
If the home was wired properly the black or red wire are hot the white is neutral and the green is ALWAYS the ground
In household wiring the black or red is active, live, or hot.
The black wire is the hot wire through which the electrical current flows to the appliance. The left over voltage which is usually zero flows back to the main circuit panel through the white neutral wire where it flows to ground.
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
The electrical terminology of a wire with no insulation on it is a bare wire.
the hot wire carries the electrical voltage

If a "hot" wire contacts the "neutral" or ground wire, electrical current flows to the ground.

ANY wire being used in electrical wiring requires over-current protection (a fuse or circuit breaker) so that the fuse will blow before an over-loaded wire gets red hot and ignites the insulation and any nearby combustibles.
In household wiring the black or red is active, live, or hot.
Even though it is a clear wire, there will be a tracer of raised or indented rib on the wire to identify the neutral. You may have to run your thumbnail around the wire to feel it rather that see it. This ribbed identified wire will be the neutral leaving the other wire to be connected to the hot side of the circuit.
One can purchase a hot wire cutter through various stores that sell electrical appliances. There are equally some online stores that sell hot wire cutter like, amazon.
Yes, some parts of the engine are hot enough to melt the insulation, at which point the metallic center can come in contact with the engine, short out and result in a fire. A wire can also rub against the engine long enough that the insulation wears off, THEN when the metallic center comes in contact with the engine, you'll still get that electrical fire.
The "hot" wire between these two coloured wires will be the blue one. The green colour is always used as ground in electrical circuits.
You hooked the ground wire to you amp to a hot wire. The hot wire is black and it's the hot wire to the cigarette lighter. I used to be a Ford mechanic and saw this alot and charged people lots of money to fix their Stupid mistake.
