From the positive battery cable but you must HAVE A FUSE BLOCK OR A SHORTED WIRE WILL CAUSE A FIRE.
Fifteen amps on the Lighter. They're usually the blue ones with '15A' on them.
5 amps
25 sq. mm. cable should take at least 96 amps, more depending on where it's installed. But if the cable gets warm consistently it is a sign that it is wasting power and it is probably economic to use a thicker cable.
124.3 amps. If you have one on a vehicle, for example a winch, use no less tha 00g cable. That is a LOT of power, and an ordinary alternator can't handle that.
6mm2 cable is rated at 40amps
Depends on the type of cable, the method of fixing the cable, the ambient temperature and the way the cable has been run to the motor (i.e in trunking, Conduit) Bascially a cable with a current carry capasity of 2 amps should be fine (1.45 amps with power factor of unity and no de-rating factors). Remember 1mm cable can carry at least 8 amps. Also please improve your English when asking stupid questions!!
A 0.15Cu cable has a rating of 382 amps summer and 476 amps winter. 0.2Cu allows 425/530 amps. That is for outdoor use in overhead lines.
Autozone says it's an 80 amp alternator. I don't know if this is the max it should put out or the average. I'm guessing the max.
The 240 sq. mm cable has a diameter of 17.48 mm. It can carry up to 425 Amps current in a duct and up to 520 Amps in open air.
445 amps. For example Mulberry AAAC cable.
Current or AMPS are what the appliance draws or load of the appliance. So, if you have a say 10,000 amps going thru a cable rated for say 1,000 amps , guess what ,the cable over heats and either will melt or at least catch fire.
A parallel run of 750 MCM AWG conductors will handle 1000 amps. if we want 1000amps to flow, 250sqmm cable is enough.
