You should never try to use more than 15 amps through a 14 gauge wire.
#14 wire is rated at 15 amps. Continuous loaded at 80% = 12 amps.
Wire is not sized by voltage. It is sized by current measured in amps. Some common copper wire sizes and their current capacities are: 15 amps -- 14 gauge wire 20 amps -- 12 gauge wire 30 amps -- 10 gauge wire 40 amps -- 8 gauge wire
A 1/0 copper wire with an insulation factor of 75 or 90 degrees C is rated at 150 and 155 amps respectively.
According to NEC, it's max rating in free air is 18 amps.
Maximum amps for chassis wiring : 101 amps Maximum amps for power transmission : 37 amps Reference : http://www.powerstream.com/Wire_Size.htm

4amps can pass in 1sqmm of wire max it is universal. In the UK 1 sq. mm wire can take 10 amps max according to tables. Cables that become warm in use should be replaced by a thicker gauge.

Use the National Electric Code wire size tables for various applications.
250 amps maximum.
