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.
The four main conductor insulation rated temperatures that are used in the electrical trade are 60, 75, 90, and 105 degrees C.
The maximum amperage that can be applied to a #14 wire is 15 amps. The 600 volts is just an insulation rating. Check the nameplate on the dryer to see what the amperage and voltage the manufacturer recommends. If the nameplate just states a wattage use the following formula to find the amperage. Amps = Watts/ Volts.
This answer is if you are referring to the sizing of electrical conductors in North America using the AWG for sizing. An American Wire Gauge sizing of 600 refers to the cross sectional area of the conductor.This amperage value is for a single copper conductor.A 600 MCM copper conductor with an insulation rating of 75 or 90 degrees C is rated for 690 and 780 amps respectively.This amperage value is for not more than three copper conductors in a conduit or raceway.A 600 MCM copper conductor with an insulation rating of 75 or 90 degrees C is rated for 420 and 475 amps respectively.This amperage value is for a single aluminium conductor.A 600 MCM aluminium conductor with an insulation rating of 75 or 90 degrees C is rated for 545 and 615 amps respectively.This amperage value is for not more than three aluminium conductors in a conduit or raceway.A 600 MCM copper conductor with an insulation rating of 75 or 90 degrees C is rated for 340 and 385 amps respectively.
The gauge of wire is referenced to the capacity of a wire to carry amperage and has nothing to do with the voltage. The voltage of a wire is determined by the type of insulation that surrounds the wire. The size of the wire is determined by the amperage of the load and the distance from the supply.
5.1v is the Voltage, You need to also look at what the Amperage rating is on the charger. 500ma, 1000ma, etc. How many Milliamps?
It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?
A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 amps.
What limits the use of a transformer is its operating temperature, as excessively-high temperature will act to break down its insulation. The temperature reached by a transformer is a function of its rating (expressed in volt amperes), so operating a transformer below its rating is perfectly okay.
V90 is a higher temperature rating than V75. V90 cables can conduct more current without over heating/melting its insulation. V110 is a higher rating than V90.
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

Usually the current rating for a circuit is higher than the current usually taken. This leaves a little margin for safety.
It depends what you mean by a 'high rating'!If you mean a high 'voltage rating' then, yes, you will require thicker insulation. But if you mean a high 'power rating', then, not necessarily, because the voltage can be low, while the current is high.Remember, the thickness of insulation depends on the voltage, while the type of insulation (how it withstands higher temperatures) depends on the current.
No, a fuse of a higher amperage rating will not usually have a higher melting point link. The higher amperage fuse will use a wider link or a link of larger diameter.
