The four main conductor insulation rated temperatures that are used in the electrical trade are 60, 75, 90, and 105 degrees C.
Kilovolts.
THHN wire is moisture resistant thermoplastic allowed for use in dry and wet locations. Maximum temperature is 60 C or 140 F. Being thermoplastic it should not be handled below 0 C as cracking of the insulation could easily occur.
A #1 copper conductor with an insulation rating of 90 degrees C is rated at 145 amps.
Wire size determines how much current can be safely conducted. Insulation type and rating determines other factors, such as where the wire can be used and maximum voltage. It should be noted that the high voltage lines that are hanging from the really large electrical towers are among a class of wires that have NO insulation around the outside of the wire. They are instead, connected to the towers with large insulators that prevent electrical energy from being lost through the towers.
A 2/0 copper conductor with an insulation rating of75 and 90 degrees Care rated at 175 and 185 amps respectively.
A #8 copper wire with an insulation rating of 90 degrees C is rated at 45 amps.
90 degrees Celsius
THHN wire is moisture resistant thermoplastic allowed for use in dry and wet locations. Maximum temperature is 60 C or 140 F. Being thermoplastic it should not be handled below 0 C as cracking of the insulation could easily occur.
A #6 copper conductor with an insulation factor of 75 or 90 degrees C both have an amp rating of 65 amps. If the #6 conductor is connected to a breaker having a 90 degree C rating then the conductor can carry an amperage of 75 amps
I think this refers to the continuous temperature rating, which is the maximum rated winding temperature allowed for a maximum ambient air temperature of 40deg C.
A 400 MCM copper conductor with an insulation temperature factor of 90 degrees C is rated at 380 amps.A 500 MCM copper conductor with an insulation temperature factor of 75 degrees C is rated at 380 amps.These conductors can have either 600 or 1000 volt insulation rating depending on what the system voltage in use is.
Yes. <<>> A #10 copper conductor with an insulation rating of 90 degrees C is rated at 30 amps. A #14 copper conductor with an insulation rating of 90 degrees C is rated at 15 amps.
Maximum power rating describes the maximum power at which a device can operate without reaching an excessive temperature. For example, in the case of a resistor, if its maximum power rating is exceeded, then it may burn out.
The 300 volt insulation rating on wire is the maximum amount of voltage that can be applied to that wire. If your range falls within that range then it is safe to use. Some commercial ranges use 480 and 575 volts. For theses types of ranges the 300 volt wire will not do, it will have to be wire with a conductor whose insulation rating is 600 volts or greater.
A #1 copper conductor with an insulation rating of 90 degrees C is rated at 145 amps.
The conductors on and in the lighting fixture should have an insulation rating of 105 degrees C. The supply conductors to the junction box that the fixture is hung from or connected to should have an insulation rating of 90 degree C.
It depends on the surround material, temperature, type of cable, and what you mean by "maximum current rating". Typically a maximum load current rating will be specified, such as 15A; this means you can push 15A through that cable nonstop without damaging it (it won't overheat). You might have a short time rating as well, such as a 4 hour rating, where the cable can handle runing 22A for 4 hours if the surrounding temperature is kept to some value, though this may slightly degrade the insulation. There's also a fusing current rating for many cables. At this current, the cable will eventually melt (like a fuse).
