101 amps for chassis wiring and 37 amps for power transmission. This is for short lengths of wire.
The normal current capacity of 12 AWG copper wire is 20 amps.
The amps that a four gauge wire will handle will depend with the thickness of the wire. If the wire is thin, the four gauge will handle 95 amps.
140 AMPS
70 amps.
55 amps on copper wire.
You are probably thinking about 1/0 wire (1 ought wire). In copper it is rated at 175 amps and in aluminum 125 amps.
10 gauge wire will only run up to 30 amps
18 amps.
You should never try to use more than 15 amps through a 14 gauge wire.
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
Generally 40 amps continuous or 50 amps surge is safe.
15 amps
