#87324 - Depends!
Responding to: ???'s previous message
The current capacity depends upon how much heating and/or how much voltage drop is acceptable in your application.

eg, UK wiring regulations give different current ratings depending on whether cable is exposed, enclosed in conduit, or buried in plaster.

Another example: a few volts drop is unlikely to be significant in a 220V mains application, but could be excessive in a 12V automotive system.

Thus it is not possible to answer your question witout further information!

Probably your best bet is to look at some catalogues for the nominal ratings given for cables designed for similar applications to yours.
Or just ask you supplier/manufacturer.

It's all based on Cross-Sectional Area (CSA), which will either be quoted directly in mm2 (or whatever), or as the diameter(s) of the conductor(s)
