For insulation.
It's actually a magnetic field, not an electric field, but the answer is 'Yes'. Pass some DC ... like from a battery that's operating a flashlight bulb ... through an insulated wire, and lay the wire over a compass. You'll plainly see that somethingthat affects the compass got through the insulation.
You would usually put a layer of insulation, often plastic, around a wire which carries electricity. However you may be looking for the magnetic field which forms when a current flows.
Insulation failure in an electrical equipment will cause some amount of current, depending upon the severity of fault flows through the metallic body and then through the earth wire which is connected to the body.
90 Degrees Celsius
Use the formula: C = (5/9)(F-32) The answer is 90 degrees Celsius.

i believe the numbers on the wire will tell you some insulated wires need to go in warm areas my guess is approx 275-300 degrees Fahrenheit
A #8 copper wire with an insulation factor of 75 or 90 degrees C has an ampacity of 45 amps. A #8 wire with an insulation factor of 60 degrees C has an ampacity of 40 amps.
A #8 copper conductor with an insulation factor of 60 degrees C is rated at 40 amps, insulation factor of 75 or 90 degrees C is rated at 45 amps.If the breakers rating is 90 degrees C then the amperage can be boosted for 60 degree wire to 40 amps, 75 degree C wire to 50 amps and 90 degree C wire to55 amps.
650 degrees Celsius
A #4 copper wire with an insulation factor of 75 or 90 degrees C is rated at 85 amps. A #2 aluminum wire with an insulation factor of 75 and 90 degrees C are rated at 90 and 95 amps respectively.
The main insulation factors of the wiring used in every day use are 60, 75 and 90 degrees C. A #6 wire can be any of the above. The higher the insulation factor, the higher the ampacity of the wire becomes. For a #6 wire the amperage is 60 C - 55 amps, 75 C - 65 amps and 90 degrees C - 65 amps.
A #14 copper wire with an insulation rating of 90 degrees C is rated at 15 amps.
A #8 wire with an insulation rating of 75 or 90 degrees C is rated at 45amps respectively.
At 0 degrees Celsius, the resistance in the wire is 1000 Ohm.
