[R-390] Can someone tell me...

[Barry]

How much current can 20-gauge (or other gauge) wire handle for normal 
chassis-wiring applications.  The wire I have is stranded, silver-plated, 
Teflon-coated stuff (very nice wire).  Looking at the various charts on the 
internet, the values seem to be all over the place so not sure what to 
trust.  Perhaps they're based on different A/circular mil -- dunno.

Thanks,
