A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.
As for the voltage, wire is usually rated in 300, 600 and 1000 volts. Any three of these insulations factors will handle 12 VDC.
A #8 wire with an insulation rating of 75 or 90 degrees C is rated at 45amps respectively.
A #10 wire with an insulation rating of 60,75 or 90 degrees C is rated at 30 amps respectively.
see American Wire Gauge. The larger the number the small the wire size.
Yes, they are the same size wire.
The frequency has no direct relationship to the size of wire. Wire is sized as to the amount of current a load draws in a circuit.
Service entrance wire should be AWG #3 copper.
A #8 wire with an insulation rating of 75 or 90 degrees C is rated at 45amps respectively.
A #10 wire with an insulation rating of 60,75 or 90 degrees C is rated at 30 amps respectively.
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps.
You would need a 12VDC to 120VAC power supply.
Switch the ignition to on. Put your meter to 12VDc. Touch the hot wire going to the solenoid with the meter positive probe . Touch the meter negative probe to ground. If you have 12VDc and you don't hear a click when you turn on the switch, the solenoid is probably bad. If you don't have 12VDc, check fuses and the wire going to the solenoid.
I'd recommend the table at: http://www.windsun.com/Hardware/Wire_Table.htm
At that distance you will have a voltage drop of 81.25 volts if you use the recommended #6 wire on a 240 volt, 100 amp single phase circuit. Therefore I recommend you contact you electric utility and let them figure the voltage drop and the size wire required to safely run this distance. Using too small a wire can damage the electronics at the end of the run.
Almost all cars in NZ have 12VDC electrics. Most portable generators which produce 230VAC, will also have a 12VDC accessory output for battery charging, etc. There are no general reticulations of 12VDC.
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
